Datasheet excerpt: Technical data of  LUC-M40

General specifications
Measuring methodThe sensor of the device transmits ultrasonic pulses in the direction of the product surface. There, the ultrasonic pulses are reflected back and received by the sensor. The device measures the time between pulse transmission and reception. The instrument uses the time (and the velocity of sound) to calculate the distance between the sensor membrane and the product surface. As the device knows the empty distance from a user entry, the device calculate the level.

Function

The LUC-M40 is a compact measuring device for continuous, non-contact level measurement. The maximum measuring range is 10 m in fluids and 5 m in bulk materials. By using the linearisation function, the devcie can also be used for flow measurements in open channels and measuring weirs.

The system integration is ensured via HART (standard), 4 mA ... 20 mA.
