Description
FS sereis flow switches is a switch with proven accuracy,ideal for critical low flow or high flow protection applications such as pump seal colling water, pump inlet flow protection,cooling loop protection, high and low flow rate alarm, valve failure, pump starting or failure, pipe blockage or rupture.Using these in-line flow switches to monitor(min/max) values of liquid flow in order to switches a valve or to establish an on or off control loop, electrical circuit is isolated from the fluid path.
A piston operated flow switch is a device withc utilizes the force exerted on a piston of flow switch in a flowing fluid to actuate an electric switch at a predetermined rate of flow. the electric switch may be used to strat or stop pumps, open or close valves, actuate a warning lamp, sound on alarm,etc.
the magnetic spring structure is more suitable for micor flow rate system.
Features
1. Easy to install, inpect and maintain. 0.05L/min or less flow rate can be detected.
2. Compact design for vertical or horizontal installations, inline or plugged.
3. Detects clogged A/C condensate drains and shuts offr the system.
4. Can be installed to activate audible and/or visual alram circuitry.
5. 6" lead wires, 3/4" plug ,3/4"slip
×3/4"MNPT adapter and 1"×3/4" reducer bushing included.
6. Suitable for 24VAC, 1.5Amp maximum.
7. variable flow cross-section can be reduce pressure drop of liuid system.
Application
The flow switch is widely used for the controls of liquid and gas. They are applied to many fields, such as paper industry,food industry,medicine, petrochemical industry, HVAC,etc. They can aslo be used in sewage treatment system, hydraulic system, cooling water system, laser system,etc.
