FCI provides flow change to protect from dry working

Fluid Components International’s dual alarm FLT93 Series move switch provides an early warning alert to the potential of dry running conditions, cavitation and other pump issues that can result in emergency shutdowns and expensive upkeep.

FCI’s FLT93 Series move change reliably screens the move and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, sudden reductions in media circulate charges can leave pumps weak to over-heating situations that shutdown process traces and require troubleshooting and fixing. The SIL2 rated instrument is meant for heavy-duty, probably hazardous process trade environments and comes with a complete list of worldwide safety approvals.
It has a no transferring elements design and offers a sturdy scheme for pump safety with its dual alarm capability. With Alarm 1, the change detects a low flow state of affairs anywhere between zero.01 and three ft per second FPS (0.003–0.9 m per second MPS). This low flow alarm is a pre-warning sign for the control system or operator who can then resolve to maintain the pump operating or to close it down.
If an Alarm 2 occurs as a end result of the feed line to the pump is running dry, this is ready to be an emergency signal to close down the pump instantly as a outcome of the bearings now see gas as a substitute of a liquid as a warmth transfer media. In such situations, the temperature of the bearings could rise very quick. Using a circulate swap prevents permanent harm to the pump’s bearings.
