Model HS-ULC -External Liquid Level Switch

The Ultrasonic Liquid Level Control is a new type for liquid level monitoring and alarming, which probes are installed outside of the tank wall, without holing on the tank make it easier to measure. It is applied for pharmaceutical industry, oil industry, chemical industry, power industry and other fields, it`s very suitable for strong toxic, corrosion and dangerous liquid level measurement. The high frequency ultrasonic pulse produced by the probe can pass through tank wall and transmit between the tank wall and liquid, and then be reflected back. By detecting and calculating the reflective behavior, the level switch can identify whether there is liquid at the monitored position. The liquid level switch can send relay signal to succeeding device or other equipment at the mean time, which can realize the function of simultaneous monitoring or controlling.
