Proline Prosonic Flow B 200 Endress+Hauser - Ultrasonic Biogas Flowmeter 9B2B

Proline Prosonic Flow B 200 is an Endress+Hauser loop-powered ultrasonic flowmeter built for wet biogas and digester gas, with real-time methane fraction measurement built in.

The full-bore sensor design adds no pressure loss and is optimised for low-pressure gas, holding measurement stability even when the gas is wet and process conditions fluctuate. Alongside flow, the device reports methane fraction continuously, so gas quality and energy balancing come from a single measuring point instead of a separate analyser. Heartbeat Technology provides in-service verification without removing the meter from the line.
