Aichi Tokei Denki Co., Ltd.
Ultrasonic Hydrogen Gas Meters High flow measurement accuracy. Hydrogen is one of the gases through which ultrasound is least likely to propagate. As a result, the ultrasonic waves that propagate through the housing (housing noise) become relatively large compared to the ultrasonic signals that propagate through the hydrogen gas, reducing the flow measurement accuracy. We have therefore adopted a unique housing shape (patented), shown in the figure, to reduce housing noise and realize highly accurate flow measurement. 10...
