Portable Ultrasonic Liquid Level Indicator

The portable liquid level indicator is designed to measure the presence or absence of liquid at a certain height position in a container or in pipelines. The material of measurable liquid containers can be made of various kinds of materials like metal, glass or unfoamed plastics. 

Portable ultrasonic liquid level indicator is the ultrasonic liquid level meter by ultrasonic technology. Especially in fire protection system using Carbon Dioxide, Halon, FM200, NAF S III, FE 13, CEA 410 & Novec 1230 Tanks. The portable ultrasonic level indicator is simple to operate and replaced the traditional means of verifying liquid levels like weighing cylinders. Portable ultrasonic liquid level indicator is the ideal choice for gas bottle level checking.

Underordinary conditions, the maximum wall thickness of measurable containers is 30mm. The product is applicable to the detection of various types of liquids (without crystallization or other particulate matter). Due to the technique of non-contact detection this liquid level indicator is an ideal choice for the detection of dangerous toxic or corrosive liquids.
