Panasonic Corporation has developed an ultrasonic gas flow and concentration sensor for hydrogen that enables the real-time simultaneous measurement of the flow rate and concentration of hydrogen ...

Gasboard-8500FS-X200 is Cubic’s ultrasonic technology 4-in-1 combined sensor solution to measure flow rate, oxygen concentration, temperature and humidity.

Moving forward, ALMACO will be the sole manufacturer and service provider for CADARO flow rate sensor technology, capable of real-time measurements for grain, fertilizer, and feed processors.

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.
