It is a direct mass flow metre, no pressure or temperature correction is required. Often, the gas flow is at low velocities. Unlike most other flowmeter types, the Manas Biogas flow metre offers remarkable sensitivity even at low velocity. Mass flow may be measured directly. There is no need to compensate for pressure or temperature. Turndown ratio of 20:1. It is possible to send data wirelessly. Wireless remote readings are provided. Outputs pulses, milliamps, and RS485 for networking.
