ULM Series Ultrasonic Level Meters
The working principle of ultrasonic level gauge is that the transducer (probe) emits a high-frequency ultrasonic pulse that is reflected back when it encounters the surface of the measured medium, and is partially received by a transducer and converted into an electrical signal. The ultrasonic pulse propagates at the speed of sound waves, and the time interval from transmission to reception of the ultrasonic pulse is directly proportional to the distance on the surface of the transducer.
- Integrated and split types are optional, suitable for different field installation requirements;
- The split type can realize single channel and dual channel selection, which can realize multi-point measurement, alarm and other functions;
- The use is simple, the results are reliable, and the interface operation instructions can reduce operating errors;
- The probe material is available in POM, PVDF, and PTFE, which is suitable for a variety of working conditions;
- An integrated temperature sensor is integrated to compensate for the speed of sound in real time.
