SPDT Water Pump Flow Switch

Flow switch for water pump liquid flow switch

 

 

Description

 

KWFS water flow switch is a device for automatic control and protection of water flow. When the water flow changes, the force generated by the water flow on the target makes the lever rotate and the control circuit close or open, thus achieving the purpose of automatic control. Water flow switch is widely used in the water system of water chiller and air conditioning engineering. It can ensure the safe and efficient operation of air conditioning system.



Application


Control and monitor liquid flow of boilers, pumps, etc., of heating, cooling, and air conditioning equipment.

Installation


The flow switch can be installed in every position far from elbows or throttlings, with arrow on flow direction. If pipe is vertical, recalibrate range to balance paddle weight. If the device is downwards mounted, take care to slags and apply it in a straight pipe that is far from filters,valves,etc.,with length at least 5 times the diameter of pipe upstream and downstream the unit.
 

Note:
The flow switch is factory calibrated at its minimum sensitivity.To increase the set valve,turn the adjustment screw clockwise.The cut-out valve must be ≥the minimum flow necessary to guarantee the protection of the plant.
