PRESENTATION

TL400-V is a non-intrusive level transmitter with no moving parts, using an infrared laser technology (~920 nm) that is completely safe to the human eye (LASER CLASS-1). Its measurement principle is based on ToF (Time of Flight), providing an accurate and reliable distance measurement, regardless of the color or transparency of the surface1 . It can be used to measure from grains and solids to transparent liquids such as water and diesel. It has a robust housing, withstanding pressures up to 6 bar, and excellent resistance to flammable materials such as diesel, gasoline, or alcohol. With a measurement capacity up to 4 meters and 1 Hz sampling, TL400-V is an excellent alternative to level sensors based on ultrasonic, capacitive, or floating technology since it does not need to be in contact with the surface to be measured. The transmitter has a dedicated filter for non-static tank applications based on machine learning algorithms that have been validated in real-life situations and have configurable parameters for specific applications.The sensor allows you to configurate the opening angle, ranging from 12° degrees for irregular tank or reservoir applications to 27° degrees for tanks where the base diameter is half the height to be measured.

TL400-V has a BLE (Bluetooth Low Energy) interface. With it you can:

  • Configure the analog output (0.5-4.5 V), according to the specific application
  • Configure the opening angle of the sensor (from 12° to 27° opening degrees)
  • Customize the tank with up to 20 points in level percentage
  • Perform sensor diagnostics in real time
  • Configure the dynamic filter based on the application
  • Update the firmware to the most current version, which will always be available on NOVUS website

These functions can be adjusted through the SigNow app, available for Android and iOS. The sensor can retransmit the analog output in Level, Volume, or Distance. Level and distance are set in your preferred unit (mm, cm, m, inches, or feet) and volume is always displayed in percent.

INSTALLATION

ELECTRICAL INSTALLATION

INSTALLATION RECOMMENDATIONS

  • Electronic and analog signal drivers must run the plant separately from the output and power leads. If possible, in grounded conduits.
  • The power supply for the electronic instruments must come from a proper power grid for instrumentation.
  • It is recommended to use RC FILTERS (noise suppressors) in contactor coils, solenoids, etc.
  • In control applications, it is essential to consider what can happen when any part of the system fails. The device internal security features do not guarantee full protection.

MECHANICAL INSTALLATION
To install the level sensor, the following tools are required:

  • 4.0 to 4.2 mm drill for the screws
  • 20 to 40 mm hole saw for the sensor
  • Pencil for marking the hole points After that, you must follow the steps below:
  1. Perform the marking: While the tank is empty, use the gasket to mark the hole points of the 5 screws and the sensor in the center of the ring. When using an adapter, mark the hole points of the 4 screws and the sensor in the center of the ring.novus-Automation-TL400-V-Laser-Level-Transmitter-fig-8
  2. Install: Use a drill with the hole saw to drill the tank in the center, where the sensor will be installed. Then drill 4 mm holes at the marked positions. The gasket has a small cutout between the longer distance holes where the sensor output cable will be positioned.
  3. Make the connections: After placing the equipment in the desired location, tighten the screws and then make the electrical connections (see ELECTRICAL CONNECTIONS section).
  4. Configure: Use the SigNow app to configure the equipment (see SIGNOW APP chapter).

TL400-V WITH AND WITHOUT ADAPTER
The figures below show versions of the equipment with and without the adapter (optional accessory):novus-Automation-TL400-V-Laser-Level-Transmitter-

fig-10

INSTALLATION EXAMPLES
The figures below show examples of how to position the equipment, according to the environment where it will be installed and considering the application:

  • Install the equipment so that the laser is perpendicular to the surface of the substance to be monitored.
  • Ensure that the equipment is positioned away from the area where the liquid or solid will be poured into the tank or reservoir.

The figures below show examples of situations to be avoided during the installation process:

  • Do not install the equipment sideways or with the laser pointing into the area where the liquid or solid will be poured into the reservoir.
  • Do not install the equipment over a faucet, which will completely block the laser.

Improper application will block the equipment from measuring the area to be monitored as intended. For this reason, you must always ensure that it is positioned perfectly perpendicular to the surface.

TL400-V is not recommended for applications in environments with direct sunlight. In such cases, measurement may be affected.

DEFINITIONS

This chapter presents definitions of terms to be considered throughout the manual.

TECHNICAL TERMINOLOGY
TL400-V uses a few specific terms, such as ullage, level, distance, and height, which can be analyzed below:

  • Ullage: Term used to describe the difference between the height of the tank and the surface of the liquid or solid.
  • Level: Term used to describe the height of the liquid or solid when compared to the bottom of the tank.
  • Distance: Term used to describe to the height between the surface of the liquid or solid and TL400-V (Offset = 0).
  • Tank Heigh: Term used to describe the total tank height.
  • Filter Type: The equipment allows using a static filter or a dynamic filter. The static filter is a moving average with a configurable response time of at least 1 second. The dynamic filter, on the other hand, constitutes a stable measurement algorithm for applications where the tank may be in motion with a fixed response time of 1 minute and 40 seconds. If you need to use the dynamic filter with another response time, please contact Technical Support.
  • Angle of View: Also known as Field of View (FoV), this parameter allows you to define the field of view for the sensor. To achieve the best sensor performance, it is recommended that it always be as large as possible. When using a sensor based on optical principles, it is important that the installation ensures that the bottom of the sensor is directed at the liquid surface in a fixed and perpendicular way, as shown in the figure below.
  • Installation Offset: Term used to describe the difference between the height where TL400-V was installed and the maximum tank height. The value must be inserted in the configured unit of measure. You must define an installation Offset when the maximum tank height and the height at which TL400-V is installed are not the same.
  • Full Tank (URV): Term that corresponds to the height of the tank at which the analog output will show a maximum value.
  • Empty Tank (LRV): Term that corresponds to the height of the tank at which the analog output will show a minimum value.novus-Automation-TL400-V-Laser-Level-Transmitter-fig-13

SOME TYPES OF TANKS
TL400-V can be used with several types of tanks, as shown in the examples below:

novus-Automation-TL400-V-Laser-Level-Transmitter-
fig-14

If the options do not fit the type of tank being used, TL400-V also allows you to create custom tanks. This feature is useful for tanks that are shaped with curves, rises, and other irregularities. When you select this option, you will need to perform a linearization at specific points on the tank. Up to 20 linearization points are allowed. The data configured in these parameters will always be in centimeters.

The custom curve can also be used to correct a possible non-linearity of the level sensor’s measurement. To use the function for this purpose, you must go to the Diagnosis tab. In the example below, the measurement inferred in the Diagnosis tab with an empty tank was 80 cm; with the tank at 50 %, it was 40 cm. Regardless of the actual distance measured by other means, simply insert the points as follows to obtain a custom curve: When using the Diagnostics tab, you must take the measurements of the desired curve and write down the distance values versus the desired percentage. Once you have all the values from 0 to 100 % with the desired number of points (with a maximum of 20 points), follow the path Configuration > Advanced > Input > Tank Calibration and insert the points as shown in the figure to the side. To delete a calibration point, simply drag it to the right. After inserting all the points, follow the path Menu > Send.

  • Before sending the configuration, it is suggested that you check the configured parameters. The parameters will be overwritten in the equipment.

To check if the curve is in accordance with the set value, you can follow the path Diagnostics > Advanced > Forcing and force a distance, which will allow you to analyze if the analog output response is adequate.novus-Automation-

BASIC CONFIGURATION
By clicking the Basic button, SigNow will display parameters regarding the basic configuration of the equipment:

By default, the equipment is already configured with the magnitude Level (the magnitude can be changed in the Input subsection of the Advanced section, as will be shown later), which allows you to configure the following parameters:

  • Device Tag: Allows you to define a tag with up to 20 characters for the equipment.
  • Level and distance: Unit: Allows you to define the unit of measurement to be used (meters, centimeters, millimeters, inches, feet).
  • Installation Offset: Allows you to define the installation Offset.
  • Tank heigh: Allows you to define the height of the tank to be used.
  • Reverse output polarity: Allows you to invert the output polarity.
  • Output minimum value: Allows you to define a minimum level value.
  • Output maximum value: Allows you to define a maximum level value.

ADVANCED CONFIGURATION
By clicking the Advanced button, SigNow will display sections regarding the advanced configuration of the equipment:

Here you can select the parameter group to be configured: Input, Output, Advanced Filter, or Security. You can also change the equipment tag.

INPUT
By clicking the Input button, SigNow will display sections regarding the input settings of the equipment:

By default, the parameter Magnitude related to the analog output is set as Level, which allows you to configure the following parameters:

  • Level and distance: Unit: Allows you to define the unit of measurement to be used (meters, centimeters, millimeters, inches, feet).
  • Installation Offset: Allows you to define the installation Offset.
  • Tank heigh: Allows you to define the height of the tank to be used.
  • Filter type: Allows you to define the type of filter to be used.
  • Viewing angle: Allows you to define the viewing angle of the equipment: 15°, 17°, 19°, 21°, 24°, or 27°.
  • Reading mode: Allows you to set the measurement mode: 1 − SHORT (for distances shorter than 1 meter), 2 − MEDIUM (for distances up to 3 meters) or 3 − LONG (for distances up to 4 meters). LONG mode is the most recommended mode for most applications. If the parameter Magnitude related to the analog output is set to Distance, these same parameters will be displayed.

When configuring the parameter Magnitude related to the analog output with the Volume option, in addition to the parameters shown in the previous figure, you can also change the parameter Tank Type (Vertical cylinder, Horizontal cylinder, Rectangular, or Custom). According to the tank type selected, SigNow will present configurable parameters to determine the size and measurement of the tank to be used. If none of the standard tank types suits your needs, you can select the Custom option.Here, you can add calibration points for the tank. You can set up to 20 linearization points by adding the desired values. The custom tank type can be useful for tanks that are shaped with curves, rises, or other irregularities. When configured to Custom, the calibrated points should go from the greatest distance to the smallest distance (smallest volume to greatest volume), as shown in the example below:

POINT DISTANCE VOLUME (%)
1 200 0
2 75 50
3 20 100

The figure at the side exemplifies the calibration points in a tank with an irregular form.

Transmitter-fig-27

  • Size of the main vector: Allows you to define the number of samples to be collected by the filter. If the user sets this parameter to 100, for example, TL400 will only consider the first 100 values collected.
  • Size of the distance vector: Allows you to select the best quality samples from among those collected by the filter (i.e., those with the least variation in values).
  • Median index: Allows you to reorder the ideal samples, i.e., those already filtered by the Size of the distance vector parameter, now according to distance.
  • Enable Blocking Filter: Allows you to enable the Blocking Filter. It prevents values that are too far off from the previous value from being displayed in the output.
  • Acceptance percentage: Allows you to define the maximum percentage of variation between the previous value and the value to be accepted by the Enable Blocking Filter parameter.
  • Percentage increase: Allows you to set the percentage of values to be incremented, according to the criterion and each time a new value outside this percentage occurs.
  • Acceptance counts: Allows you to set the maximum number of times that the Blocking Filter, enabled in the Enable Blocking Filter parameter, can reject data outside the standard defined in the Acceptance ratio parameter.
  • Acceptance ratio: Allows you to reduce the oscillation or data peaks of the analog output. The ADVANCED FILTER chapter provides more complex information on how the parameters of this filter work, as well as examples and graphs.novus-Automation-TL400-V-Laser-Level-Transmitter-fig-28

SECURITY
TL400 allows you to protect the device’s connection with a password. By default, the password is disabled. However, it is possible to create a numeric password of between 4 and 10 digits. Once the device has received a password, the connection can only be made by entering it. This feature prevents access by unauthorized users. If the configured password is lost, the master password can be used, consisting of the number 9 + the last 3 digits of the serial number.

  • Master password = 9 + last three digits of the device’s serial number.

WHEN USE THE ADVANCED FILTER
There are applications in which the sensor may show instabilities in level measurement. In general, these instabilities are related to the optical properties of the application, such as reflective walls and the incidence of sunlight. In these cases, to improve the result, TL400 has a filtering algorithm that is based on the quality of the measurements of a group of samples. The advanced filter can be configured within the Advanced Configuration section of SigNow app (see ADVANCED FILTER section of SIGNOW APP chapter). By configuring certain parameters, this algorithm can significantly reduce measurement instabilities. To better exemplify the need to use the advanced filter in certain situations, below is a real example of a measurement that doesn’t need the filtering algorithm (left) and one in which it was necessary to use it (right). The raw measurement is in blue; the filtered measurement is in orange.novus-Automation-TL400-V-Laser-Level-
Transmitter-fig-35

Internally, the algorithm is based on a sample sorting logic that acts according to the quality measure of the measurement itself and based on sorting according to the distance to collect the most stable measure of the group (median). Below is a description of the parameters and their influence on the measurement result.

A MORE DETAILED EXPLANATION OF THE ADVANCED FILTER PARAMETERS
The Advanced Filter of SigNow app is composed of 8 parameters. Below, it is possible to see a more complex explanation about their functioning.

“SIZE OF THE MAIN VECTOR” PARAMETER
This parameter allows you to define the number of samples to be collected by the filter. If the user sets this parameter to 100, for example, TL400 will only consider the first 100 values collected. The higher the value set, the greater the number of samples, the more stable the result (since there is a greater amount of data to analyze) and, consequently, the slower the filter.

“SIZE OF THE DISTANCE VECTOR” PARAMETER
This parameter allows you to select the best quality samples from among those collected by the filter (i.e., those with the least variation in values). More precisely, the vector will order the samples from the lowest standard deviation to the highest standard deviation (always considering the value 1 as the ideal standard deviation), creating an internal ordering, not visible to the user. Thus, the first measurement on this list will always have the smallest deviation and is theoretically the most accurate within this margin. When performing an analysis from 1 up to the size configured in the Size of the main vector parameter, the measurements in this set will be those that survive after the other values have been discarded. If you put 100 in the Size of the main vector parameter and 20 in Size of the distance vector, for example, the parameter will select the 20 best of these 100 samples, rejecting the others. This parameter must be smaller than the one configured in the Size of the main vector parameter. The lower the value, the more selective the filter will be, and the fewer samples will be considered. The more unstable the behavior of the sensor, the “worse” samples should be discarded and therefore the smaller the Size of the distance vector should be. When looking for greater stability and in conditions where response time is relevant, it is possible to increase the Size of the main vector and the Size of the distance vector. By setting the Size of the main vector parameter to 400 and the Size of the distance vector parameter to 350, for example, an 80 cm measurement application will have an accuracy of 3 millimeters.

“MEDIAN INDEX” PARAMETER
This parameter allows you to reorder the ideal samples, i.e., those already filtered by the Size of the distance vector parameter, now according to distance. In this case, the Median index parameter will ignore the standard deviation, opting instead to analyze the median, which would be thecentral number of these values (the number of times that a value is repeated among the number of samples), either increasing or decreasing. The Median index displays the position of the value in relation to the median containing the output value to be considered by the filter. The values that are most repeated among the samples collected are given the position 0 as an index. Samples with lower values receive negative indexers, while higher values receive positive indexers. If the sensor is “missing too much” when collecting data, it is possible to reduce this difference by selecting a smaller position, using a Median index value that is less than 0. The figure below exemplifies the position of the median, according to symmetrical situations (ideal situation not in line with reality), distortion to the right (negative indexers) and to the left (positive indexers):novus-Automation-TL400-V-Laser-Level-
Transmitter-fig-36

ENABLE BLOCKING FILTER” PARAMETER
This parameter allows you to enable the Blocking Filter. The Blocking Filter prevents values that are too far off from the previous value from being displayed in the output. Whenever the TL400 collects a new sample, it assesses whether it is within this acceptance percentage. If so, it will be accepted. Otherwise, it will be ignored. Once Enable Blocking Filter has been enabled, the maximum percentage of variation allowed must be set in the Acceptance percentage parameter.

ACCEPTANCE PERCENTAGE” PARAMETER
This parameter allows you to define the maximum percentage of variation between the previous value and the value to be accepted by the Enable Blocking Filter parameter. If the current value exceeds the percentage set in this parameter, the Blocking Filter will ignore the discrepant value. In situations where the TL400 identifies variations of more than 5 % between samples and if the Acceptance percentage parameter is set to this percentage, for example, it will only accept variations of up to 5 % between one sample and another.

PERCENTAGE INCREASE” PARAMETER
This parameter allows you to set the percentage of values to be incremented, according to the criterion and each time a new value outside this percentage occurs. If values fluctuate outside the percentage defined in Percentage increase, for example, certain measures will no longer be accepted, and the acceptance rate will be increased by the increment. Whenever a new measure fails to enter, the acceptance criterion is increased, increasing the chance that the next sample will be accepted.

ACCEPTANCE COUNTS” PARAMETER
This parameter allows you to set the maximum number of times that the Blocking Filter, enabled in the Enable Blocking Filter parameter, can reject data outside the standard defined in the Acceptance ratio parameter. That is, it will register the number of occurrences of new measures being blocked and, when it reaches the maximum value configured, it will accept these new values at a percentage defined in the Acceptance ratio. The Acceptance counts parameter is complementary to the Percentage increase parameter. If the value set in Acceptance counts is reached, the blocking filter will accept the next values, even if they exceed the value set in the Percentage increase parameter. This allows data to be collected even during sudden changes in level. When filling the tank quickly, for example, this parameter prevents the TL400 from taking too long to identify changes in the tank level, since it will start accepting new samples after a sudden variation has occurred repeatedly and has reached the value set in this parameter:novus-Automation-
TL400-V-Laser-Level-Transmitter-fig-37

ACCEPTANCE RATIO” PARAMETER
This parameter allows you to reduce the oscillation or data peaks of the analog output. When it collects a new value, it analyzes the acceptance rate, which is why this new value will be accepted. If it is 1, the new value accepted will be the new value itself. If it is 2, it will be half the new value.

USAGE EXAMPLES

EXAMPLE 1: 3-METER HIGH AND 2-METER WIDE WATER TANK
In one application, the user intends to apply the sensor to measure a tank in a water tank with a tank height of 3 meters, the maximum level being 2.8 meters and with the bottom of the tank as the minimum level. It is also expected to get the current measurement proportional to the level, i.e. 20 mA at the maximum level (minimum distance) and 4 mA at the minimum level (maximum distance). Here is an example of parameter configuration for this application:

  • Magnitude related to the analog output: Level
  • Unit: cm
  • Tank height: 300 cm
  • Offset: 0 cm
  • Filter type: Static
  • Filter time constant in seconds: 20
  • Angle of view: 27°
  • Reading mode: Long
  • Error action on analog output: None
  • Invert output polarity: No
  • Value for minimum output : 0
  • Value for maximum output : 280

EXAMPLE 2: 80 CM OIL TANK
When performing the diagnosis of the measurements that fill the tank of an oil tank with 80 cm high and 10 cm wide, it was verified that, although proportional to the level, the informed measurement did not match the real value. In this case, as shown in the information below, the user intends to correct the sensor reading with a 5-point curve:

PERCENTAGE OF VOLUME FILLED (PERCENT)| DISTANCE MEASURED ON DIAGNOSTIC TAB (CM)| REAL DISTANCE (CM)
---|---|---
0 % – Empty tank| 100| 80
25 %| 85| 60
50 %| 50| 40
75 %| 25| 20
100 %| 10| 0

In this case, you must insert the points through the following path: Configuration > Advanced > Input > Tank Calibration, as shown in Figures 36 and 37. Then, in Diagnostic > Advanced, you can check the volume according to the distance, depending on the configured calibration. When using the custom curve, the tank height value will be ignored for the volume calculation.
