  • Page 3: Fcc Conformity

    FCC CONFORMITY This instrument complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this instrument may not cause harmful interference, and; (2) this instrument must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.

  • Page 4: Using The Display

    USING THE DISPLAY The display module features a dot matrix LCD display with 4 push buttons on a removable puck. Out of the box, the display indicates level in feet and depicts the level within the 4-20mA span on a bar graph at the right side of the display. The four buttons perform the following functions: ...

  • Page 5: Basic Configuration Overview

    BASIC CONFIGURATION OVERVIEW Below are the 9 basic steps to configure the sensor for operation. Each step is described in detail on the following pages 1) Measure the Tank a) Begin by measuring the key tank and fitting dimensions. Correct tank dimensions will result in accurate sensor measurement.

  • Page 6: Step 1 - Measure The Tank

    STEP 1 – MEASURE THE TANK Measurement Reference Chart Measuring the tank is one of the most important aspects LR36 & LR41 Series LR46 Series in configuring the sensor. When measuring the tank, take into account the location of the sensor with respect to fittings, risers, dome tops and bottoms, and identify where the measurements are taken from the sensor.

  • Page 7: Step 2 - Set The Units Of Measurement

    STEP 2 – SET THE UNITS OF MEASUREMENT This function sets the units for all measurement values to be entered into the sensor. The choices for units are feet and meters. The unit is shipped with a default setting of feet. 1.
  • Page 8 STEP 3 – SET THE SENSOR HEIGHT (4mA) This function sets the Sensor Height point corresponding to an empty position in the tank. The measured distance of Sensor Height from the sensor will set the 4mA location as well as establish the 0% span of the sensor.
  • Page 9 STEP 4 – SET THE FILL-HEIGHT (20mA) This function sets the Fill-Height point corresponding to a full position in the tank. The measured distance of Fill-Height from the 0% or empty position will set the 20mA location as well as establish the 100% span of the sensor.
  • Page 10 STEP 5 - SET THE MAX. RANGE (MAXIMUM RANGE) This function sets the maximum operational range for the sensor. This setting defines the maximum distance that the sensor will detect valid echo returns. 1. From the Main Screen, press Enter to advance into the Main Menu.

  • Page 11: Step 6 - Set The Dead Band

    STEP 6 - SET THE DEAD BAND This function sets the Dead Band for the sensor. This setting defines the minimum distance that the sensor will detect valid echo returns. While the Dead Band setting is typically configured to be equal with or slightly above (higher in the tank) the Full Configuration setting (20 mA), its functions independently of Full Configuration.

  • Page 12: Step 7 - Check The Echo Curve

    STEP 7 – CHECK THE ECHO CURVE This function displays the primary echo return(s) that the sensor is seeing graphically, the location and amplitude of the return(s), and the numeric air gap distance from the sensor’s measurement location to the liquid level below. Note: This step should only be performed after having completed the prior six configuration steps with the sensor installed on the tank.
  • Page 13 STEP 8 – INSTALL THE SENSOR (INSTALLATION REQUIREMENTS) In order to measure as much of the solids volume as possible, the antenna must be aimed at the lowest point within the tank. With any cylindrical shaped tank with a cone bottom, the sensor should be mounted a distance of half the radius (½R) from the side wall.
  • Page 14 When using the gimbaled flange, the sensor can easily be mounted to direct the signal energy towards center of the tank. The angle of the sensor will be dependent on the distance down to the bottom of the tank and the distance away from the bottom of the cone.

  • Page 15: Beam Angle

    BEAM ANGLE The emitted microwave pulse will expand along its specified beam angle for the entire height of the tank. Place the sensor so that objects will not interfere with the beam path underneath the sensor. The beam angle is a function of the sensor Series and antenna length (where variable). Verify the beam angle specification of your sensor and reference the below charts to determine the amount of free measurement space required under the installed sensor.
  • Page 16 ANTENNA PREPARATION In order to fit the antenna into an application, it may be best to attach the sensor to a flange before mounting inside the tank. The antenna can be removed and the sensor mounted to the flange with the antenna re- attached afterwards.
  • Page 17 STEP 9 – WIRE THE SENSOR Remove the Display: To access the terminal strip and conduit ports, you first need to remove the display. Gently twist the display counter-clockwise until you feel the display unlock from the housing. Next, lift the display from the housing to view the terminal strip and wire access ports.

  • Page 18: Analog Output (4-20 Ma)

    ANALOG OUTPUT (4-20 MA) ® The analog output of the EchoPro is a loop powered 4-20 mA control circuit. The typical way to use this feature is to connect a positive supply to the (+) input and to sense the current flow out of the (-) output with a sampling resistor as shown in the following control drawing.
