Getting started

Power supply

The meter is powered by an internal rechargeable LiPo battery. With a fully charged battery, an operating time of approx. 8 … 10 hours is possible, depending on the brightness of the display. The battery is charged via the USB socket at the bottom of the meter, using a suitable USB charger. The charging process can be shortened by switching off the device during the charging process.
The current charge level of the battery is displayed in the status bar at the top right. As soon as the charge level of the battery is no longer sufficient for proper operation of the instrument, it switches off automatically and the screen shown below is displayed.

Preparation

The meter is switched on by pressing the ON/OFF key. When the device is switched on, the start screen appears for approx. 1 second and then the device enters the measurement screen. To switch off the meter, keep the ON/OFF key pressed. A dialogue with a countdown now appears on the display to announce that the instrument is about to power off. The flow sensors are connected by simply plugging them into the sockets provided at the top of the device. They are disconnected by pulling the plugs, touching the ribbed surface to unlock the plug connection. Screw the plugs into the sensors using the knurled nut. The thermocouples are also connected by plugging them into the sockets provided. The plugs have a wide and a narrow contact. These determine the orientation of the plug when it is plugged in.

Menu

The main menu can be opened at any time by pressing the MENU key. The arrow keys are used to navigate between the menu items which can be activated with the OK key. Submenus can be left with the BACK key. The main menu of the PCE- TDS 200 series consists of the submenus Measurement, Data logger, Settings, Calibration, Manual and Info. The submenus are explained in more detail in the following chapters.

Measurement

Measuring principle and measuring methods

The flow meter enables the flow velocity of liquids in pipes to be measured without interfering with the pipe and without affecting the flow in the pipe. To enable non-invasive measurement, the PCE-TDS 200 uses two sensors that work as both ultrasonic transmitters and receivers. The sensors are attached to the outside of the pipe wall at a defined distance. To enable the transmission of the ultrasound, a coupling gel must be applied to the sensors in this case. When ultrasonic signals are transmitted with and against the flow direction of the liquid, differences in transit time occur which can be converted into the flow velocity. The sensors can be mounted according to four different measurement methods which are shown below.

Z method

1 Upstream sensor, 2 Sensor distance, 3 Downstream sensor, 4 Flow direction
The more frequently the sound crosses the liquid, the more accurately even very small flow velocities can be measured. However, the signal strength decreases with each crossing, which is why the W and N method cannot be used for every pipe, for example. It is recommended to use the V method if the pipe parameters allow it as this produces the best results in terms of signal quality and zero point stability. However, if the signal quality is too low, the Z method can be used.

Getting started

Measuring location
The first step of the installation should be to find a suitable place to mount the sensors. This is a prerequisite for obtaining accurate measurement results. For this, a basic knowledge of the pipelines / the piping system is necessary. Therefore, an infinitely long, straight pipe would be the ideal position. The liquid should not have any air pockets or impurities. The piping can be vertical or horizontal. To avoid inaccuracies due to turbulence in the liquid, a straight flow-calming section should be considered upstream and downstream of the measuring location. Generally speaking, the length upstream of the measuring location should be at least 10 x the pipe diameter and downstream of the measuring location 5 x the pipe diameter.

The following chart shows some examples of good positions:

Sensor installation
The PCE-TDS 200 has piezoelectric sensors which can transmit and also receive ultrasonic waves. The time the ultrasonic waves take to pass through the pipe walls and the liquid allows conclusions about the flow velocity. Since the transit time of the ultrasonic pulses is very short, the sensors should be installed as precisely as possible to ensure highest system accuracy.
Take the following steps to install the sensors:

1. Some pipes have a liner. There can be a boundary layer between the outer diameter of the pipe and the inner liner. This boundary layer can divert or weaken the ultrasonic waves. In this case, a measurement will be very difficult. The same applies to external coatings on the pipe, such as paint. This must be removed before the measurement so that you can measure.
2. Find an ideal position in the piping system, i. e. a straight section with new and clean pipes with even surfaces.
3. It is very important that the pipes are clean. Grind or polish the locations where you would like to place the sensors so that the contact surface is even.
4. There must not be an air gap between the sensors and the surface of the pipe. Attach the sensors using sufficient contact gel. Also, tighten the fastening straps firmly enough so that the position of the sensors cannot change during the measurement.
5. To avoid air bubbles from causing measurement errors, place the sensors on the pipe laterally. Note that in this case, the flow could not be calculated correctly by the device due to the pipe not being completely filled.

Spacing between the sensors

The distance between the upstream and the downstream sensor can be seen in the installation view of the measurement screen (see 6.4). The window specifies the inner distance between the two sensors which can be used as an indication for the sensor installation. The fine adjustment is carried out by arranging the spacing in a way that the distance indicator is as central as possible within the graph (see 6.3).
In order for the PCE-TDS 200 to calculate the correct distance, the following parameters must be entered beforehand:

1. Outer diameter of the pipe
2. Material thickness of the pipe
3. Material of the pipe
4. Material thickness of the pipe liner
5. Material of the pipe liner
6. Type of liquid
7. Type of connected sensors
8. Mounting method of the sensors
9. Temperature of the medium

Procedure

Before making the measurement, also read the previous chapters 6.1 and 6.2 to gain an understanding of the measurement principle and its influencing factors.
To carry out a measurement, it is first necessary to set all parameters in the Measurement menu (see 5.1) completely in line with the pipe used, the medium, the sensors, the measurement method and the temperature. After all parameters have been set and checked, go back to the measurement screen and navigate to the installation view. The installation view shows the measurement method, the set sensors and the distance between the sensors.

Note:
Note that in the case of the Z method, the sensors may also overlap.

Mount the sensors according to the described measurement method with the appropriate distance and apply sufficient coupling gel to the sensors. The meter should now be able to receive a signal and display this via the quality indicator. If the quality indicator is within the green range, you can continue with the distance setup. If there is no signal or a poor signal, check the settings again and follow the preparation steps described in chapters 6.1 and 6.2.
Now adjust the distance of the sensors so that the distance indicator is as central as possible within the green area. A good setting is shown below.

After setting the distance, the meter is ready for operation and the measurement can be made.
Since the zero point may be shifted depending on the measuring conditions (installation, pipe material, etc.), it is possible to reset the zero point in the installation view. To do this, it is necessary to ensure that the liquid in the pipe does not move!
In the installation view, press and hold the OK key until the confirmation dialogue opens and confirm the setting of the zero point. While the meter is determining the zero point, a waiting dialogue is displayed. After this has closed, the zero point is set.

In order to carry out a heat quantity and heat output measurement, it is also necessary to connect the temperature sensors to the device and attach them to the corresponding measuring locations. Temperature channel 1 must be attached to the warmer measuring location (e. g. the feed line of a heating system) and channel 2 to the colder measuring location (e. g. the return line of a heating system).

Measurement display

Navigation

• To ensure a clear presentation of the measured parameters, the measurement display consists of several views. Each view represents a measured parameter which is displayed in the upper blue area of the view. Switching between the views of the measured parameters is possible with the RIGHT and LEFT arrow keys.
• Some parameter views also have several formats for displaying the parameter, such as the simple numerical display, the graphical display or the display of the statistical values (minimum value, maximum value and average). The display format can be changed using the UP and DOWN arrow keys. The following illustrations show the different display formats for viewing the parameter flow velocity.

• The following chart shows the available formats of representation of the measured parameters.
