Datasheet excerpt: Technical data of LUC-M**
| Function and system design | ||
|---|---|---|
| Measuring principle | The 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. | |
| Equipment architecture | 4 ... 20 mA output with HART protocol system integration via PROFIBUS PA |

Function
The LUC-M** is a compact measuring device for continuous, non-contact level measurement. Depending on the sensor, the measuring range is up to 15 m in fluids and up to 7 m in bulk solids. By using the linearisation function, the LUC-M** can also be used for flow measurements in open channels and measuring weirs.
The system integration is ensured via
-
HART (standard), 4 mA ... 20mA and
-
PROFIBUS PA.
