The device is built around a cheap 1/2″ brass water flow rate sensor connected to his shower hose, which outputs pulses as a small wheel passes an internal hall effect sensor.

When water flows through a household water meter, a magnetic disc spins inside of the meter, which correlates directly to a water flow rate. The Flume sensor measures the magnetic field from the ...

This represents the industry's first sensor1 enabling real-time simultaneous measurement of the flow rate and concentration of hydrogen under a highly humid environment.

FCI’s reliable ST75 Flow Meter utilizes advanced thermal dispersion sensing technology, providing accurate and consistent measurements even in challenging environments.
