How-to Replace a Submersible Transducer with the LPU-2428 Ultrasonic Level Sensor


In this video, Shaw Merrill of APG will be showing you how to program your LPU-2428 Ultrasonic Sensor using the submersible option in the LPU-2428 programming software.


The submersible option is used when you are replacing a submersible sensor or pressure sensor such as the PT-500 Submersible Pressure Transducer with a LPU-2428 Ultrasonic Level Sensor.

00:20 To begin programming the LPU-2428:

  1. Click on the basic setup button on the left side of the screen.
  2. Select the units to be displayed on the right.
  3. Set the application to submersible.
  4. Click the send button near the bottom of the screen to send these settings to the sensor.

Wait until the progress bar completes before moving to the next step.

00:39 Now we are ready to setup the remaining parameters.

  1. Click the application setup button on the left menu and set submersible range to the maximum range of the submersible sensor.
  2. Set the depth distance to the distance from the sensor face to the furthest target being detected.
  3. Click the 4-20 Setup button on the left of the screen and verify the 4-20 set point values are set correctly. (The minimum mA set point, this is the 4 mA setting, is usually set to 0.)
  4. Press the send button to save these settings and wait for the progress bar to complete.

01:14 Your sensor is now setup and ready to go.

01:17 The remaining advanced features in the programming software will default to automatic settings. To change these settings, please refer to the LPU-2428 user manual programming section.

01:26 Thanks for watching our quick LPU-2428 programming demo.
