HS-ULC External Ultrasonic Level Switch

Description

The HS-ULC External Ultrasonic Liquid Level control is a new type of liquid level monitoring and alarming instrument. This instrument is mainly used for monitoring liquid level in a tank and alarming when the level reaches maximum or minimum. It can be also used to identify the existence of liquid in pipe. Such measurement technique is not interfered by medium density, permittivity, conductivity, reflection coefficient, pressure, temperature, precipitation or other factors. Therefore it can be applied to level control of various types of liquid in industries of pharmaceuticals, petroleum, chemical, electricity, food and so on. It is an ideal choice for the detection of dangerous toxic or corrosive liquid.

Working Principle

The sensor of the level controller uses a coupling agent to couple the generated high-frequency ultrasonic pulses to the container wall. The pulses will propagate through the container wall and the liquid, and will also be reflected by the internal surface of the container. By detecting and calculating the reflected signal characteristics, the measured data is transmitted to the field secondary table through the 485 serial port in real time, you can judge whether the liquid level has reached the controller installation position.
