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.
