Product Details
AM-ULM-D ultrasonic level differential meter is an instrument used to measure the difference between two liquid levels. It is based on ultrasonic technology, it is to install the ultrasonic transducer above the measured object. The ultrasonic transducer emits sound wave signals and simultaneously receives the sound wave signals reflected by the measured object. By measuring the time difference between transmission and reception, the measurement distance is calculated according to the propagation speed of sound waves in the air. AM-ULM-D ultrasonic level differential meter has two ultrasonic level sensors that measure the level difference by transmitting and receiving ultrasonic signals.it’s widely used in measuring the liquid level difference before and after the grille in various industries such as rivers, lakes, sluices, and ship locks.
