THE SYSTEM

The field transmitters of the COMBIMASS® eco series are suitable for biogas flow measurement with process temperatures up to 130°C and gas pressure up to 1,3 bar especially developed for key account customers with framework contracts. The flowmeter can be supplied for ATEX Zone 2 without an integrated display.

The electronics of the COMBIMASS® oem-bio L is located in a aluminium enclosure. Applications are flow rate measurement and balancing of biogas flows in sewage treatment and anaerobic digestion plants, in a gas mixture of well known composition. The calibration conditions are fixed for all instruments and need an adaptation to the local situation by the customer.
