The FlexSwitch FLT93 Flow Switch from FCI - Fluid Components International reduces pump repair and extends life by detecting dry running conditions. It monitors the flow and temperature of liquids, gases and slurries. It is ideal for pump wet/dry detection, where unexpected reductions in media flow rates can leave pumps vulnerable to overheating damage. With Alarm 1, the switch detects a low flow situation between 0.01 and 3 feet per second. This low flow alarm is a prewarning signal. The system operator can then decide to keep the pump running or to shut it down. If an Alarm 2 occurs because the pump feed line is running dry, this is a signal to shut down the pump because the bearings now see gas — instead of a liquid — as a heat transfer media. 760-744-6950; www.fluidcomponents.com.
