NivuFlow Extension Module for flow measurements with up to 32 paths


The NivuFlow Extension Module permits flow metering which meets the highest accuracy standards. In connection with NivuFlow 6 transmitters it is possible to use up to 32 paths per measurement. The amount of cables needed is extremely low since the measurement paths are bundled directly on site. This moreover reduces expenses and efforts for installation and cable laying.

One Extension Module combines up to eight paths which then are routed to a NivuFlow transmitter through one single line. By utilising 4 extension modules it is hence possible to use up to 32 measurement paths.

The robust and weatherproof enclosure complies with IP 65 standards and has been developed particularly for installation in the field.
