Correcting a Coriolis Meter for Two Phase Oil & Gas Flow
It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...
متن کاملTest Benches for Calibrating Custody Transfer Gas Meter
Several transmission and distribution companies in Western Europe operate test facilities for testing industrial meters like larger diaphragm gas meters, rotary gas meters and turbine gas meters. Alternatively, they lease mobile provers. Those installations are not suitable to perform the initial calibration (and try to save money on the calibration costs), but are suitable to perform all kind ...
متن کاملCalibration of a Quadrupole Gas Analyzer Using a Reference Gas*
A quadrupole gas analyzer system was calibrated for the gases H2, He, N2, 02, A, and Xe. The procedure involved first calibrating the system for argon, as the reference gas. This was done using conventional techniques. A mixture of the above gases was then introduced into the system to be calibrated. The system configuration was such that the ratio of the partial pressures of each of the test g...
متن کاملGas-liquid chromatography: the gas-density meter, a new apparatus for the detection of vaporus in flowing gas streams.
The separation of volatile substances by gasliquid chromatography (James & Martin, 1952; James, Martin & Smith, 1952; James, 1952; James & Martin, 1954; Ray, 1954a, b) requires that the substances be detected as they leave the chromatogram in the stream of gas that acts as the mobile phase of the system. A number of methods of detection of varying sensitivity have already been developed (James ...
متن کاملNeonate capillary blood gas reference values.
OBJECTIVES Because biological data are instrument-dependent and because technology has evolved over the last two decades, the published capillary blood reference values for blood gases, lactate, ionized calcium (iCa) and glucose may not reflect the present day situation. Hence, we report such values for healthy term neonates at 48 +/- 12 h of life. DESIGN AND METHODS The Institution Ethics Re...
