ZHM CI Series

Gear Flow Meters for Oil and Gas Applications

Gear flow meter ZHM CI Series is a dedicated version, which is primarily used in applications for the upstream oil and gas market. Specific and robust design enable our gear flow meters to meet flow metering challenges like high pressure ratings, pulsating flow streams, corrosive media and harsh environment conditions. They perform with outstanding accuracy in oil and gas exploration processes and hydraulic monitoring applications.

Their reliability and long-term durability combined with exceptional engineering and production tolerances ensure customers an accurate measurement, efficiency increase and prompt return of investment due to cost reduction in chemicals used for instance.
