I.Summary:
The ball float liquid level controller output 4 ~ 20 mA stadard current signal and matching with the III type electric instrument, which can realize the automatic detection , control and record for the liquid level. The liquid level transmitter is suitable for oil refining industry, chemical industry, paper making, food and pharmaceutical industries, and applicable for the medium liquid level measurement such as sewage and all kinds of exposure or pressure containers, for underground storage tanks and high-level water tank level measurement are ideal. Liquid level transmitter is made of stainless steel or anti-corrosion materials, and has the explosion protection performance.
