The portable liquid level indicator is designed to determine the presence or absence of liquid at a certain height in a container or pipeline. The liquid containers to be measured can be made of various kinds of materials such as metal, glass or un-foamed plastics. 

Under ordinary conditions, the maximum wall thickness of the measured container is 30mm. The indicator can be used to detect various types of liquids (without crystallization or other particulate matter). Because of the innovation non-contact detection methods, this liquid level indicator is an ideal choice for detecting dangerous toxic or corrosive liquids.
