The main features:

RISEN-RJFG ultrasonic interface meter is specialized for the on-site continuous observation and measurement of sewage interface in sewage treatment. The device applied reliable ultrasonic echo measurement theory to measure the distance between the probe and the surface of sewage, it realized the instantaneous observation, measurement and control of the changing surface height of sewage, therefore an optimized mudd emission control and feeding control can be realized and to prevent effluent deterioration etc.

This meter applied the original RISEN floating mudd echo identification technology and real temperature compensation technology, so as to keep measurement accurate and precise with long term stability; It combines complete measurement, control, signal transmission and man-machine communication function. This meter integrates ultrasonic receive and send sensor, service circuit, temp compensation sensor and compensate circuit unit, display and control signal output and serial signal or analog quantity output unit(optional)
