ABM Ultrasonic Level Transmitters

  • Rejects false signals
  • Simple push-button calibration
  • Reliable and easy to operate design

 

 

The ABM Ultrasonic Level Transmitters allow simple and reliable non-contact level measurement of fluids in a tank, sump or other container. The microprocessorcontrolled circuit generates a pulse that is transmitted from the transducer face. This pulse is reflected back from the surface of the liquid. The "round trip" transit time is then converted into the current output, which is directly proportional to the fluid level.

The circuit automatically filters out false echoes that may be produced by peripheral obstructions in the tank. For example, a pipe or ladder that is in the "ultrasonic cone" (but not directly in front of the transducer's face) will be ignored; the ABM Series has a proprietary circuit that locks onto the farthest echo which will always be the fluid level.

Use with any SCADA or process controller, or the optional remote display.
