Description
The Xylem-McDonnell & Miller FS7-4D Fs7-4 W/2 Spdt 119750 is a flow switch intended for use in HVAC systems. This is a powerful apparatus that keeps track of the fluid flow in hydronic systems, usually water or glycol. If the flow rate reaches or falls below a predefined threshold, the switch recognizes it. The switch turns on and transmits an electrical signal to the HVAC management system at that moment. This signal has the potential to trigger multiple events, contingent on the configuration of the system. This can activate pumps, open or stop valves, or set off alarms, for example. The FS7-4D contributes to the safe and effective operation of the HVAC system by monitoring and controlling fluid flow.
