GEMS flow switch quotation

RFS US GEMS Adjustable Flow SwitchIntroduction:

Combine visual flow state with electronic switch action
Concise and adjustable switch point calibration; When the set point is reached, the LED signal is displayed

RotorFlow switchRaise the reliability of your equipment to a new standard. Based on the working principle of the rotor, it will not indicate a flow state in the absence of flow. Once an action point is set, RotorFlow will indicate a "no flow" state regardless of whether the rotor stops working for any reason.

Set point calibration using LED signal (F6RFS type)

After installing and powering on the pipeline, complete the following steps to calibrate the flow value at the switch action point.
The only tool required is a straight screwdriver.

1. Adjust the flow rate on the pipeline to within the range of the switch action.
2. Insert a screwdriver into the opening behind the casing and into the adjustment screw of the potentiometer.
3. If the LED does not light up, slowly rotate the screwdriver clockwise until the LED lights up.
4. If the LED is on, slowly rotate the screwdriver clockwise until the LED goes out.
Then slowly rotate the screwdriver counterclockwise until the LED lights up
