MEMPRO level transmitters are designed for level in tank with atmospheric pressure, unclosed tank or basin.
When the level increases, the fluid rises inside the tube. The pressure of air trapped inside increases as well.
This pressure corresponds to the height of the water column outside (from the bottom tube end). The ceramic pressure sensor delivers a signal 4-20 mA equivalent to the level of fluid. This type of level transmitter is not affected with contaminated liquids or crystallizing fluids, as long as the stem is not tapped. Venting connection integrated in the top: as an option, a venting module is connected for out-gassing and encrusting liquids refreshing; it resets the air column when media temperature changes during the process. MEMPRO transmitters are suitable for aggressive liquids since the wetted parts are of PVC, PP or stainless steel for the stem and ceramic for the sensor. Different scales are available, with various ranges (set up with dipswitches).
