Flow Switch, Water Flow Switc Hfs-25

Hfs Series G1/2 G3/4 G1 Brass Fire-Resistant Liquid Control Sensor Pneumatic Valve Flow Switch

Product Description  

HFS Paddle Flow Switch is an automatic control unit which switches on or off in response to the flow or non-flow of a liquid media. The switch typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it.

Flow switches enable the reliable and process-safe monitoring of fluid. When the flow is above or below the set value, built-in SPDT micro switch activates downstream regulator or control, such as a pump, an alarm, a water chiller or heat exchanger. Damage and production losses through degradation of pumps, tools and spindles can thus be avoided.

Flow switch be mountedin a horizontal pipe line or vertical pipeline .

Mount the instrument in a section of pipe where there is a straight run of atleast 5pipe diameter on each side of the flow swhtch

Adjustment

Note :sealed adjustments are not field addjustable .

Adjust Setting

1,Remove switch cover

2,For higher flow rater-turn range adjusting screw clockwise

3,For lower flow rater-turn range adjusting screw counter clockwise.

4,Be sure flow swtich cover is replaced before leaving job.
