Multiphase Flowmeter

The FMC Measurement Solutions TopFlow Multiphase Metering Sytem provides accurate and continuous measurement of liquid, water and gas, and is ideally suited to supplying crude oil production well operators with real time flow regime statistics. Overview The TopFlow Multiphase Flowmeter is a second-generation multiphase meter that assimilates conventional metering components into one compact flow tube.

The sensor is a simple venturi design incorporating capacitance plates and a differential pressure transmitter to measure the flow rates of oil, water and gas accurately and continuously without the use of a radioactive source or the need to condition the flow stream with separation devices, mixers or by-pass lines. The flowmeter covers a wide operating range, all water cuts, salinities, viscosities and flow regimes with minimum permanent pressure loss.

Applications
The TopFlow Multiphase Metering System provides real time information on well flow with respect to variations in gas versus liquid flowrates. Installing a meter on each well monitors production capability as well as providing early warning of problems associated with gas lifting systems or onset of severe slugging conditions. Additionally, the TopFlow multiphase meter requires less maintenance than conventional test separators and eliminates the hazards associated with chemicals used to separate oil from water, resulting in reduced operating costs.

Features
Non-radioactive - the flowmenter is free of a radioactive source ensuring a safe and less complicated operating environment.

Compact Design - the slim, short and lightweight design of the meter allows for ease of installation and a significant reduction in offshore platform space.

High performance - with minimal pressure drop and the ability to meaure flow rate independent of changes to the flow regime, the TopFlow flowmeter provides reliable and accurate measurement results equal to or better than those obtained from a test separator.

Flexibility - the meter can be operated as a stand-alone unit and / or interfaced to customer data aquisition systems.

Low maintenance - the meter and all associated components of the system require minimal to no maintenance, significantly reducing operating costs.
