ULM–55_–02 Dinel Ultrasonic level meter

Ultrasonic level meters ULM® is self contained device, that includes electroacoustics transducer and electronic module. The level meter ULM transmits series of ultrasonic pulses, which propagates towards the liquid surface. Reflected acoustic wave is received back in the ULM transducer and processed in electronic module. The distance calculations are based on time of flight of the acoustic wave to the level and back. Ultrasonic level meters are for continuous non-contact level measurement of liquid and paste materials. The performance is "N" (normal) usable in non-explosive areas only and "Xi" (explosive proof).
