Ultrasonic Level Sensor

Industrial ultrasonic level transmitter uses a non-contact ultrasonic level sensor, continuous level measurement ultrasonic sensor of liquids and materials. With built in technology to compensate temperature. It has anti-interference intelligent identification and error correction function. No moving parts. They are widely used in all kinds of atmospheric storage tanks and water areas. Pokcenser ultrasonic level sensors have different models for small-range, mid-range and long-range applications, explosion proof, IP67 or IP68, including water and waste water, chemical processing, food and beverage, pulp and paper processing, sump and process tanks.
