Introduction

The Pyxis LSR-801 Series sensors are W-band FMCW continuous frequency modulation radar level transmitters. They provide continuous level measurement up to 591 inches (49.2 ft. or 15 m) with 4-20 mA output as well as RS485, BlueTooth 5.0®. The LSR-801L is also equipped with LoRa (Long Range Radio) digital output for long-distance wireless level sensor data access. The LSR-801 Series can be wirelessly configured via the Pyxis uPyxis® app for Mobile or Desktop devices enabling rapid integration and deployment in the field. The sensors are powered by a 24 VDC / 2.5W external power supply and are ideal for use with commonly used OEM controllers, PLC or DCS systems. This non-contact liquid level sensor platform is well suited for corrosive liquids and can be used for industrial, municipal and process liquid storage as well as chemical feed applications.

Installation

4.1 Wiring

The LSR-801 Series level sensors should be powered by a 24V DC power supply from any standard controller, PLC or DCS. The sensors offer both 1x 4-20mA and 1x RS-485 Modbus outputs. The 24V DC negative (black wire) and 4-20mA- wire are internally connected from the LSR-801 Series sensor therefor it is unnecessary to connect the green to the 4-20 mA negative terminal in the controller. If a separate DC power supply other than from a controller is used, make sure that the output from the power supply is rated for 22-26 VDC @ 100mA. Under standard installations the clear wire is not landed and remains unused.

NOTE Pyxis recommends powering off the controller when landing wires to the controller terminal board while the adapter to LSR-801 series sensor is connected. Follow the wiring table below to connect the sensor to a controller or receiving device.

4.2 Tank Top Installation and Precautions

The sensor should be installed in a 2-inch bulkhead fitting on the top of the tank. The dimensions of the LSR-801 and LSR-801L sensors are shown in Figure 2. If a flat horizontal surface is not available on the top of the tank, please use a self-aligning bulkhead fitting so that the sensor can be adjusted to be perpendicular to the liquid surface.

  • Install and adjust the sensor to be perpendicular to liquid surface
  • Installation location should not be too close to container wall to avoid interference.
  • The sensor has a 1.97 inch (5 cm) dead zone (DZ). Raise the probe to avoid the DZ if desired
  • Do not install in a location which will cause the microwave to be obstructed

6.6 Parameter Setting via uPyxis Desktop App

Click Setting to set the parameters as show in Figures 10 – 12. The sensor measures the distance between the liquid surface in the tank and the bottom sensor surface. Converting this measured distance to other parameters such as the tank level, the remaining liquid volume, or the consumed liquid, requires the tank dimensional and volume capacity information. Common vertical tanks have a uniform horizontal cross section. As such, the liquid volume is proportional to the liquid level. To convert the measured distance to volumetric information, it requires the user to enter three parameters via the uPyxis Mobile or Desktop apps as shown in Figure 10.

The Maximum Height (Figure 10) is the liquid level measured from the tank bottom when the tank is filled to the rated Volume capacity. The Installation Height is the distance between tank bottom and the sensor bottom surface. NOTE Please make sure that the difference between the installation height and the maximum level height is greater than 1.97 inches, the sensor dead zone.

For horizontal or other tanks that have a non-uniform cross section, please contact Pyxis Technical Support team (service@pyxis-lab.com) for assistance.

6.7 4-20 mA Output Setup

The 4-20 mA output of the LSR-801 series sensor will be scaled as outlined below following user configuration via uPyxis.

4 mA = (Tank is Empty) = (Level is 0) = (Distance is Installation Height),
20 mA = (Tank is Full) = (Level is maximum height) = (Distance is Installation Height –  Maximum Height).

The 4-20 mA analog signal can be converted to one of four values (Level, Distance, Volume Remaining, or Volume Consumed) in the controller receiving the output according to the above scale.

For example, a nominal 100-gallon vertical tank, the maximum height is 36 inches and installation height is 42 inches. The tank volume is 100 gallons when it is filled up to the maximum height of 36 inches. The controller should be set up to convert 20 mA to 100 gallons, at which the tank is full and the tank level is 36 inches and the distance measured is 6 inches (installation height – maximum height).

  • NOTE * The nominal capacity provided by the tank manufacturer may be greater than the maximum safe (net or effective) capacity that can be practically filled. Please keep this in mind as you configure your LSR- 801 series sensor for practical purposes. Unlike other sensors on the market, the LSR-801 series level sensor does NOT require the storage tank to contain liquid to be properly configured. The user may configure the sensor on an empty tank or prior to installation if desired.

Communication Using Modbus RTU

The sensor can be configured as a Modbus slave device via RS-485. In addition to the level, volume, and distance, many operational parameters, including warning and error messages, are available via a Modbus RTU connection. Contact Pyxis Lab Customer Service (service@pyxis-lab.com) for more information.

Communication Using LoRa (For LSR-801L Only)

LoRa (short for Long Range) is a wireless radio communication technology that allows low-power devices to communicate with a LoRa capable Gateway over long distances. Pyxis Lab has added LoRa capability to the LSR-801L radar level sensor for future utilization with Pyxis LoRa embedded 4G Gateway technology. After the sensor with LoRa is powered-up, it will automatically register into the LoRa gateway within range allowing collection of operational parameters from the sensor, including level, volume, distance, settings etc. The LoRa gateway acts as a bridge between the sensor and the Internet or Controller, and it can communicate with many sensors at the same time. Pyxis Lab LoRa embedded 4G Gateway is currently in the final stages of development. Contact service@pyxis-lab.com to find out details of availability.

Sensor Maintenance and Precaution

For best performance, keep the antenna lens clean using a soft cloth or towel. Please note that in some applications, buildup on the antenna lens can affect the measurement results. If necessary, clean the antenna lens in as needed intervals.
