Rheonik Coriolis flowmeter proves itself
28 May 2013
The large-size flowmeter from GE has been accurately calibrated by a compact prover without the need of intermediate turbine meters.
Pipe provers have often been used in the oil and gas industry as a means of validating flowmeter use for custody transfer, and to meet fiscal standards.
Until recently, compact provers have had difficulty calibrating large flowmeters because they are designed for smaller volumes.
Errors have occured when the integration period between the flow and the system data have lagged. The piston and the small volume prover have to be compatible when passed between detectors to avoid these mistakes.
The Coriolis meter had been one such difficult device as it measures mass flow, and most small provers lag behind the actual flow rate.
The latest tests have been carried out using a compact prover, an OMNI flow computer and a density meter.
The verified results show an average stable meter factor and a repeatability of less than +/- 0.1% and the flowmeters proven range go up to 12”.
Uwe Hettrich, product manager for GE’s Rheonik product line, explained that the Coriolis meter is “unaffected by viscosity, density or pressure changes and can be used in a wide range of line sizes.”
