The ultrasonic level transmitter is a non-contact, low-cost and easy-to-install measuring device. It can be applied to most industrial applications for both solids and liquids. Most important aspect of is that it is easy-to-install and low maintenance due to know moving parts.


During operation, the device emits a wave to the medium to be measured. The wave reflects off the surface and moves back to the device where a transducer calculates the distance. The distance is based on the time interval between transmission and reception of the wave. D= (334.1+0.6t) x T/2, where the D = the transmission distance; t = temperature; and T= transmission time. With 4~20mA output, it can be connected to the PLC,DSC and SCADA systems. In addition, it is also equipped with exclusive PULSE and AGC (Auto Gain Control) echo tracking technology to ensure accuracy and precision even in the harshest environments.
