FCI offers move change to guard from dry running

Fluid Components International’s dual alarm FLT93 Series flow switch supplies 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 flow change reliably screens the flow and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, where sudden, sudden reductions in media flow rates 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, potentially hazardous course of business environments and comes with a complete listing of global safety approvals.
It has a no moving components design and provides a sturdy scheme for pump protection with its dual alarm capability. With Alarm 1, the switch detects a low circulate scenario wherever between 0.01 and 3 ft per second FPS (0.003–0.9 m per second MPS). This low move alarm is a pre-warning sign for the control system or operator who can then resolve to maintain the pump running or to close it down.
If an Alarm 2 occurs as a result of the feed line to the pump is working dry, this would be an emergency sign to close down the pump instantly as a result of the bearings now see fuel as a substitute of a liquid as a warmth switch media. In such conditions, the temperature of the bearings could rise very fast. Using a flow switch prevents permanent damage to the pump’s bearings.
