Kem Kupper ZHM CI Series Gear Flow Meters

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 enables our gear flow meters to meet flow metering challenges like high-pressure ratings, pulsating flow streams, corrosive media, and harsh environmental 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

We work in very close cooperation with our customers to meet their individual measuring requirements. Thanks to our varied manufacturing capabilities, we are able to offer a wide range of flow capacities, connection sizes, and exceptional materials of pressure-related parts.

In addition, we develop specific designs for onshore installations and offshore fields topside or subsea equipment in conjunction with the highest possible chemical compatibility. Optional components and materials like low-friction stainless steel ball bearings or tungsten carbide sleeve bearings with nickel binder guarantee high-performance operations.
