Seperated ultrasonic level meter

Aisonic separated ultrasonic level meter adopts non-contact measurement technology, the measured medium is almost unlimited, and it can be widely used for level measurement of municipal inland river, urban groundwater level, sewage treatment station, waterworks, etc.


  • Two-wire system, four-wire system is optional.

  • Suitable for non-contact measurement of liquid, slurry, sludge and other media.

  • The maximum measuring range can reach 50m.

  • English interface is optional

  • The analog output is 4-20mA with Modus485 communication.

  • Provide alarm current output to prevent liquid level from entering blind area or exceeding range

The Advantage of Ultrasonic Liquid Level Meter Compared with Manual Measurement of River Level

  • There is a certain danger in manual field survey on the river bank (the depth of the river is 5m)..

  •  Can still continue to work in bad weather.

  • The value measured manually is not very accurate and can only be used as a reference.

  • The labor cost is high.Besides, it is necessary to record the field data many times a day.
