  • Application : This switch is widely used for water treatment system, central air conditioning, water cooling unit and fire system.
  • Suitable Media : The switch is mainly used to measure the dynamic state of the liquid flowing through the pipeline, including water, ethylene, and other liquids that have no corrosive effect on copper.
  • Feature : The control value is adjustable and the action repetition point is stable. Interface dimensions: 1/2in (HFS-15), can fits most of equipment.
  • Note : The HFS switch shall not be used in pipelines where the liquid temperature drops below the freezing point of the liquid. The HFS switch cannot be hit by water. If there is a quick closing valve in the downstream of the switch, the throttle must be used.

Matters needing attention:

  1. The flow switch can be installed in the horizontal pipe or the vertical pipe with the upward direction of liquid flow, but it cannot be installed in the pipe with the downward direction of liquid flow. Gravity should be considered when installing in piping above the flow direction of the fluid
  2. The flow switch must be installed on the straight pipe of the section, both sides of which are short of the straight stroke of 5 letter pipe diameter. At the same time, it should be noted that the direction of liquid flow in the pipe must be consistent with the direction of arrow on the switch shell.
  3. When installing wiring, please pay attention to the following matters:

  • it is absolutely forbidden to impact the wrench on the switch bottom plate, resulting in deformation failure of the flow switch;
  • when wiring, it is absolutely forbidden to adjust any screws other than micro switch terminals and grounding screws. It should be noted that the micro switch wiring cannot be usedt
  • he blade of the flow switch cannot contact with the inner wall of the pipe and other throttles in the pipe, otherwise the switch cannot be reset normally.

Regula muy bien los dispositivos de encendido de la bomba, muy buen producto.

Not sure why this won't trip with water flow, it makes absolutely sense. Out of curiosity I tested the weight required to move the paddle. It move at a pressure of only 28grms. So for it not to trip in a stream of 55psi/5.5gpm makes zero sense.🤷🏼‍♂️

When installed in a tee the finger needed extensive origination to fit. Never did get the switch to engage as the water flowed around the top of the finger. It’s a nice heavy duty switch but would take lots of work to function properly.

No sirve, requiere de mucha presión para funcionar, nunca activo la bomba por más que le busque, decepcionante

No description in the package as to which paddle goes with what pipe size. I used the longest paddle for a 2" pipe and the unit would not screw in without pipe contact. The midsized was too short to get adequate actuation. Don't buy if you need less than a 10gpm flow indicator.

Works great, comes with different paddles for different size pipes. I use it to ensure water is flowing for a heater to turn on.
