Explosion-proof Ultrasonic Liquid Level Control with Alam Monitoring Function (Model: HS-ULC)

Product Detail

Product Description

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.

Application Fields

1. Measurable Tank Material: The probe installation area on tank wall should be hard material with good conductivity such as carbon steel, stainless steel, various hard metal, fiber glass, epikote, rigid plastic, ceramics, glass, rigid rubber and other composite material. The internal and external surface of installing position should be smooth. If there are multipal layers in tank wall, the layers should compact without foam or air gap such as sulfide rigid rubber lining, epikote lining, stainless steel lining, and titanium.


2. Tank wall thickness: 2-70mm

3. Measurable tank type: Horizontal tank, spherical tank, vertical tank and so on. 

4. Medium: The measurement result is not interfered by density, permittivity, temperature, pressure, purity, viscosity of medium
