Engineers responsible for municipal or industrial water storage, disinfection or effluent treatment systems will find the FlexSwitch® FLT93 Flow Switch from Fluid Components International (FCI) reduces pump repair and extends pump life by detecting dry running conditions.
Municipal water and industrial wastewater treatment systems depend on pumps to move water through storage, disinfection, effluent treatment and delivery. Pumps are expensive to operate and costly to maintain--especially when dry running conditions suddenly occur due to system variable demand, leaks, clogs or other problems that can end up damaging pump seals or bearings.
The result can be emergency shutdowns, expensive service interruptions and major pump repairs, overhauls or even full replacement.
FCI’s dual alarm FLT93 Flow Switch reliably monitors the flow and temperature of liquids, gases, slurries and more. It is ideal for pump wet/dry detection, where sudden, unexpected reductions in media flow rates may leave pumps vulnerable to over-heating conditions.
The FLT93 Flow Switch, with its no moving parts design, offers a highly 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 FPS (0.003 to 0.9 meters per second MPS). This low flow alarm can be regarded as a pre-warning signal for the control system or operator. The system or operator can then decide to keep the pump running or to shut it down.
