Subsea flow meter is intended for deepwater oil and gas production modules and operations. It is suitable for the subsea production environment. It relies on a differential pressure flow sensor designed with built-in flow conditioning to achieve more accuracy. It operates over a flow range of 10:1, and comes in line sizes from 0.5 to 120 inches. This design is inherently more accurate because the flow conditioning function is built-into the basic flow sensor design. It can be installed virtually anywhere in a piping system or be easily retrofit into an existing piping layout, providing installation flexibility.
