Endress+Hauser has introduced the Proline Prosonic B 200 ultrasonic flow meter for measuring the flow rate and methane content of wet biogas, landfill or digester gas, and other low-pressure, wet or contaminated gases.
The unit provide measures and displays direct methane fraction as a function of sound velocity and temperature without additional measuring instruments. Possible outputs include corrected methane volume flow, energy flow, calorific value, temperature and Wobbe index. The device detects changes quickly, allowing operators to make prompt corrections to improve process control and energy balancing.
Automatic data backup by the HistoROM function provides storage for 1,000 measured values, quick restoration
