PR Series Hydrostatic Pressure Level Sensors for Turbulent Tanks The MAD4520 Flush Submersible Series is the latest addition to Madison’s line of hydrostatic pressure level sensors. It is designed for monitoring viscous material and/or turbulent conditions within a vessel. This cost-effective sensor is approved to UL/cUL913 Class 1 Division 1 IS, Groups C and D, with an approved barrier. There are four pressure ranges available, and the cage design allows for proper media flow while keeping the sensor at the bottom of the vessel or well. MAD4520-x hydrostatic pressure level sensor for turbulent tanks The 316L and PVDF construction will withstand the toughest environments. The MAD4520 is ideal for sewage lift stations, food tanks and viscous media applications. Other typical uses include: grease and lubrication tanks; drilling mud pits; vegetable and animal oil tanks; and storm and industrial holding tanks.
