Mercoid Series 195
Two Stage Top Mount Displacer Type Level Control — Fixed or Adjustable Deadband, For Pumps or Alarms
Two Stage • Dual Setpoints • UL Approved
One of the most versatile level controls available, the Mercoid Series 195 can be used on all types of tank or sump level control applications. The Series 195 provides two stage control — dual setpoints for pump and alarm service in a single unit. Mercoid® Displacer Controls use displacers that do not float on the surface of liquids, but are suspended on a coil spring.
They work on the principle that submerged solids weigh less in liquids — as the liquid level rises and their weight decreases, the tension on the spring is decreased. Because they work on a different principle than float type liquid level controls, displacers are not affected by turbulence or pressure, and are excellent for applications with viscous or dirty liquids.
