K-BAR 2000B-WGF Series Multipoint Insertion Flow Meter

Brand: Kurz Instruments

K-BAR 2000B-WGF multipoint insertion flow meter is engineered specifically for wet stacks, condensing gas environments, and biogas applications.

The K-BAR WGF processes the dry flow signal independent of the effects of moisture in the process gas stream.

K-BAR 2000B-WGF flow meters have effectively no impact on the flow stream, proven high accuracy, and are highly economical for both initial and maintenance costs.
