What does a flowmeter do in an Espresso Machine?

Flowmeters measure the volume of water going through the groups - the water used for brewing the espresso. It does this by recording the revolutions of the impellor inside the flowmeter chamber. These revolutions are sent back to the PCB and interpreted as water volume. The most common flowmeter found in espresso coffee machines are Gicar Flow meters - made just outside Milan in Merate – Italy since 1963.

The most common flowmeter is the metal 3-prong flow meter which is ungrounded. The connectors are connected back to the PCB by a block connector. Some brands like Fracino  Rancilio & Marzocco have the ground prong wired back to the flow meter body to ground it.
