Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.

Panasonic has released an ultrasonic meter that can simultaneously measure hydrogen flow rates and concentration in high humidity. Ultrasonic flow meters use ultrasound to measure the velocity of ...

Hydrogen has long played a key role as an industrial feedstock in petroleum refining, fertilizer production, and chemical manufacturing. However, conventional methods of producing hydrogen generate ...
