  • Page 5: Basic Configuration Overview

    BASIC CONFIGURATION OVERVIEW Below are the six basic steps to configure the transmitter for operation. Each step is described in detail on the following pages. 1) Measure the Tank Measure the significant tank and fitting dimensions. 2) Install the Transmitter Review the installation requirements to locate and install the sensor on the tank.

  • Page 6: Step 1 - Measure The Tank

    STEP 1 – MEASURE THE TANK Properly locating the sensor and correctly measuring the tank sets the foundation for sensor configuration. In doing so, consider the sensor’s mounting location with respect to relevant fittings, risers, dome tops or cone bottoms, and identify where the measurements are taken from the sensor.
  • Page 7 TOP OF TANK CONSIDERATIONS When installing EchoBeam ® on an enclosed tank top, the installed position of the sensor’s antenna or measurement location, above or below the top, must be taken into consideration when determining your sensor configuration settings. Tank Top Installation Short Riser Installation Tall Riser Installation SENSOR OUTPUT TO LOCAL DISPLAY/CONTROLLER...

  • Page 8: Step 2 - Install The Transmitter

    STEP 2 – INSTALL THE TRANSMITTER EchoBeam ® measures the air gap distance between the bottom edge of the sensor’s antenna and the liquid or solid media surface. To properly install the sensor, adhere to the following installation best practices: 1) Locate the sensor where there are no obstructions between the bottom edge of the sensor’s installed antenna and the bottom of the empty tank, including its measurement beam angle.

  • Page 9: Step 3 - Wire The Transmitter

    5) Install the sensor in accordance with all applicable national, state or local safety requirements such as the United States National Electrical Code (ANSI/NFPA 70) or the Canadian Electrical Code. 6) While adhering to the minimum free space requirements, based on the model, install the sensor with the following minimum distances away from the tank side walls: LR81: >...
  • Page 10 Note: The sensor should be wired with shielded 2-conductor cable (16 to 22 AWG) to protect from electromagnetic interference. If using a liquid tight connector, select a cable with an outer diameter that is designed to ensure an effective seal with the connector [typically between 0.20” to 0.35” (5 to 9 mm)]. HART Wiring: An advantage of the HART protocol is that it can communicate over existing 4–20 mA analog current loops.

  • Page 12 STEP 4 – ADJUST THE DIMENSIONS Once the sensor’s installed, you may need to adjust the LR81 Series original Sensor Height and Fill Height dimensions based on the final mounted position of the sensor in its fitting. To assist, the below offset dimensions reflect the distance between the top of the sensor’s mounting threads or flange, to the bottom of the sensor’s antenna or point of measurement.

  • Page 14 Screen 3 – Set the Fill-Height (20mA) Input the distance from the bottom of the tank to the maximum fill level, which defines the 20mA set point. Screen 4 - Set the Display Value Select the level height, air gap distance, current or percent of span value that the sensor will display.
  • Page 15 STEP 6 – CHECK THE ECHO CURVE This function graphically displays the primary echo return(s) the transmitter sees, the location and amplitude of the return(s), and the numeric air gap distance from the transmitter’s measurement location to the level below. Note: This step should only be performed after having completed the prior four configuration steps and with the transmitter installed on the tank.
  • Page 16 What is a Good EchoCurve? EchoCurve presents a physical representation of the return signal across the operational range for the radar transmitter. There are two components to observe when looking at the EchoCurve: • Check the Peak(s) along the EchoCurve o Ideally, there should be a significant peak which represents the liquid or solids level in the tank.
  • Page 17 • Multiple peaks before or after the liquid or solids level ® o If there are multiple peaks, the EchoBeam have trouble identifying which is the correct peak (liquid or solids level). o Performing a False EchoCurve will allow the EchoBeam ®...
  • Page 18 DIAGNOSTICS • False EchoCurve o Obstructions in the tank (mixer blades, side wall weld joints, material build-up, submersible pumps, piping or other apparatus), tall tank risers or installation fittings can create false signal returns that impair the transmitter’s measurement. o This function maps all echo returns within the tank, differentiating between good and false echoes.
