WP320 Magnetic Level Gauge is one of the on-site level measuring instruments for the industrial process control. It is widely applied in the monitoring and process control of liquid level and interface for many industries, such as Petroleum, Chemical, Electric power, Paper-making, Metallurgy, Water treatment, Light industry and etc. The float adopts design of 360 ° magnet ring and the float is hermetically sealed, hard and anti-compression. The indicator that uses hermetical sealed glass tube technology clearly displays the level, which eliminates the common problems of glass gauge, such as vapour condensation and liquid leakage and etc.
