Description

 

KWFS target flow switch is a type of shell made of ABS and PC composite materials, which can effectively protect against high-temperature corrosion. Meanwhile, its blades are made of stainless steel, which can well meet the needs of customers.

It is mainly used to measure and control the flow of liquid flowing through pipelines, such as water, ethylene glycol, etc. The typical application of the target type flow switch series is to use it in places where interlocking action or disconnection protection is required. The series of flow switches uses a large load single pole double throw (SPDT) open target switch, featuring fast action characteristics, ensuring the instantaneity of the flow switch.



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.
