Description

1/2″ 3/4″ 1″ Water Flow Switch 304 Stainless Steel HFS-25 20 15 Adjustable 220VAC 15A Liquid Water Flow Paddle Control
Features: 
This flow switch is made of high quality stainless steel, corrosion resistant and long service life. 
This product is used to measure the fluid dynamics of fluids passing through pipes, such as water, ethylene diluents, glycols and other liquids that do not corrode copper. 
This water flow switch is suitable for water treatment systems, central air conditioning, water cooling units, fire protection systems and other fields. 
Flow switches are typically used in locations that require interlocking or “cut” protection. 
When the flow exceeds the set value, the fluid drives the blade and the microswitch, and the SPDT contact can connect the circuit and disconnect other circuits.

Installation method: 
1.Open the flow switch. 
2.The switch has been set at minimum flow rate.Turn the adjusting screw counterclockwise to increase the flow setting value. 
3.Press the target to check whether the micro switch can work normally. Excessive clockwise rotation of the adjusting screw may lead to the failure of the flow switch. 
4.After the installation, please press the lever of the flow switch several times to check. If there is no “click” sound, turn the adjusting screw counterclockwise until there is “click” sound. 
5.The adjustment screw of lacquer seal is only used for the first time to adjust the state of flow switch.
6.Observe three operating cycles to ensure that the switch and the system to which it is connected are operating properly and cover the switch enclosure promptly.
