Ultrasonic Transit Time Flowmeter Proline Prosonic Flow B 200

Measuring principle

Ultrasonic flow

Product headline

The device for accurate, reliable biogas measurement with loop-powered technology.

Inline flowmeter designed for measurement of wet biogas and digester gas under fluctuating process conditions.

Sensor features

Optimized for low pressure gas – specialized sensor design. No additional pressure loss – full-bore design. Process transparency – diagnostic capability.

Multivariable device: flow, temperature and methane. Medium temperature: 0 to 80 °C (32 to 176 °F). Process pressure: 0.7 to 11 bar a (10.2 to 159 psi a).

Transmitter features

Convenient device wiring – separate connection compartment. Safe operation – no need to open the device due to display with touch control, background lighting. Integrated verification – Heartbeat Technology.

Loop-powered technology. Robust dual-compartment housing. Plant safety: worldwide approvals.
