Usonic Ultrasonic Continuous Level Transmitters


The Drexelbrook USonic level transmitter provides a level measurement utilising a non-contact ultrasonic sensor.

The Drexelbrook family of ultrasonic instruments offers an affordable two wire and line powered version for non-contact ultrasonic level measurement of liquids and slurries for level, distance, volume and open channel flow. The instruments in this series are suitable for use in a wide range of applications and industries.

All measurements options are easily configured through the menu driven display. The USonic ultrasonic level transmitter is offered with a two wire 4-20 mA, HART output signal and is designed for either Intrinsically Safe or Explosion Proof installations in Class 1 Div. 1, Zone 0 environments. The bench configuration eliminates the need to move process material levels for calibration.


  • Patented SMART GAIN circuitry automatically ignores false echoes from internal tank obstructions and agitator blades without adjustment. This makes it an ideal choice as an ultrasonic tank level sensor.
  • Superior accuracy – 0.15% of measuring range up to 30 ft
  • Two-wire HART intrinsically safe or explosion proof, suitable for Class 1, Division 1, hazardous locations
  • Output mode: Level, Distance, Flow, Volume
  • Power supply: 19 to 30 VDC. 19 VDC required at 4 mA minimum
