Ultrasonic Gas Flow Meter – B series

The B series Ultrasonic Gas Flow Meter adopts the principle of ultrasonic time difference.

Ultrasonic Gas Flow Meter – B series

Ultrasonic Gas Flow Meter uses the superposition relationship between the propagation velocity of the ultrasonic signal in the fluid and the fluid velocity for measurement. Ultrasonic Gas Flow Meter-B series is mainly for gases with a single composition such as oxygen, nitrogen, argon, helium, etc. There are also gases such as flare gas and natural gas. The price/performance ratio is very high.

Sino-Inst offers a variety of  Ultrasonic gas flow meters for flow measurement. If you have any questions, please contact our sales engineers.

Application field

Example: B-FS600C represents B flare gas flow meter. Measuring pipe section DN600. Measuring C gas.

According to the application scenario. B series gas ultrasonic flow meters are divided into B-D type and B-F type.


The Z series rectifier can effectively improve the upstream and downstream measurement conditions of the gas ultrasonic flowmeter. Improve the accuracy of the measurement structure. The Z series rectifier adopts a tube segment honeycomb rectifier. It is connected with the flow meter and the pipe section through a flange. The rectifier plate is made of stainless steel. The meter head is made of stainless steel or cast steel.
