Flow switch for water pump water pump flow sensor

Description

KWFS is installed in a water pipe and is a detection element that contacts fluid. When there is no water in the pipe or water does not flow, the target flow sheet is in a natural state; When there is water flowing, the target flow sheet is impacted and stressed, and the greater the water volume, the greater the impact force. When the flow reaches a certain value, the water flow pushes the target flow sheet, converting the flow signal of the water into a displacement signal of the target flow sheet. When the flow rate increases to the upper limit of the set value or decreases to the lower limit of the set value, the target flow sheet pushes the microswitch action of the control device through the transmission mechanism, outputting a control signal to the device.

Application

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

Note:
①For flow rates with suffix "Z", the 6 inch paddle must be installed.
②The flow rate unit of the above table is GPM (m /h)

Electrical Wiring

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.
