Dinel ULM-70 Ultrasonic Level Meter

Dinel ULM-70 Ultrasonic Level Meter for Industrial Process Control Applications

The Dinel ULM-70 Ultrasonic Level Meter range uses the speed of sound to calculate the level of a liquid or solid by sending out pulses of sound that reflect back off the materials surface. The ULM-70 ultrasonic level meter is capable of continuous measurements  and has an adjustable min/max measurement level with an absolute max of 20m. Ultrasonic level meters are suitable when the substance being measured is volatile or high temperature and conventional “contact” methods of measurement are not ideal; however, foam, steam, smoke, etc., can interfere with measuring.
