The meters can measure flow rates of many types of fluid, while exhibiting very low pressure drop. Designed to operate in harsh environments, they have no moving parts or special mounting or flow-conditioning requirements. Motion's Elite Coriolis flowmeter. The device is installed downstream from wells producing oil with a high-percentage water content. The equipment drives high-pressure sound waves, at appropriate frequencies, into the emulsion flow stream.
Acoustic separation works by vibrating microscopic particles in the fluid.
The flow stream containing the separated liquids then moves to a conventional separator for final separation and collection. The device was tested on a well producing heavy oil with a high content of solids, which had used chemical separation techniques. Degassing fluids improves the accuracy of fluid measurement by eliminating much of the gas from the emulsion. The technology is used in the company's PhaseTester and PhaseWatcher production well-test services. PhaseWatcher equipment is permanently installed and remotely operated.
