4-20mA Output external liquid level meter, the probe attached outside of tank (Model: HS-2000)
This intelligent ultrasonic liquid level meter is designed to advanced signal processing technology and high-speed signal processor. It overcomes the obstacle of tank wall thickness, and ultimately achieves non-contact measurement of liquid height in hermetic tanks.
The ultrasonic sensor (probe) is designed to be mounted at the bottom of the tank exine without holing on the tank so that easy assembly is, hence, realized and the measurement will not interrupt the normal operation of the liquid tank. It is suitable to acquire accurate liquid level measurement for high pressure hermetically tank containing toxic, strong acid, strong alkali and various kinds of pure liquids. Note that the meter has no special requirement of medium or material of tank, and it is explosion proof. Therefore it has wide application under various conditions.
