operating principle : the flow meter is a component made up of a turbine with a magnet, in a plastic material shell. With the passage of water, the turbine turns, and the magnet passes in front of a micro-contact to send a flow of pulse to the management card of the device.

1 Pulse (or turbine tower) then corresponds to a volume of water.

as a function of the number of pulses, the device will then stop the water supply to obtain the right water dosage in your cup of coffee, or to determine when the descaling must be carried out.

diameter of the inner nozzle D = 1.2 mm or an eligible flow of 0.05 - 0.40 l/min depending on pump and circuit shock.
