Barksdale's single-point float-type level switch provides a variety of solutions for your specific level control problems. UNS-MS 1/4 NPT-BN30 Level Switches are ideal for use in storage tanks, hydraulic power units, lube oil console systems and other general applications for level measurement. This Series features an intermediate size float for applications with more vertical clearance ( 2-9/16" stem length), and is suitable for rugged service and use in high viscosity liquids. Switch polarity on all models can be changed from normally-open to normally-closed by simply rotating the float 180 degrees. For your level switching and control needs requiring only a single float, Barksdale's UNS Series Level Switches are the ideal solution.
