The FlexSwitch FLT93 Flow Switch from FCI - Fluid Components International reduces pump repair and extends pump life by detecting dry running conditions. It reliably monitors the flow and temperature of liquids, gases and slurries. It is ideal for pump wet/dry detection, where sudden, unexpected reductions in media flow rates may leave pumps vulnerable to over-heating conditions. With no moving parts, it offers a robust scheme for pump protection with its dual alarm capability. With Alarm 1, the switch will detect a low-flow situation anywhere between 0.01 and 3 feet per second. If Alarm 2 occurs because the feed line to the pump is running dry, this condition would be an emergency signal to shut down the pump immediately because the bearings now see gas instead of a liquid as a heat transfer media. 800/854-1993; www.fluidcomponents.com.
