Method And Apparatus For Determining Real Gas Effects In Critical Flow Nozzles
Method And Apparatus For Determining Real Gas Effects In Critical Flow Nozzles
US Patent:
4706492, Nov 17, 1987
Filed:
Jun 16, 1986
Appl. No.:
6/874731
Inventors:
Emrys H. Jones - Yorba Linda CA
Robert E. Jackson - Coraopolis PA
Robert E. Jackson - Coraopolis PA
Assignee:
Chevron Research Company - San Francisco CA
International Classification:
G01F 2500
US Classification:
73 3
Abstract:
A method and apparatus for determining the gas flow rate in a high pressure critical flow nozzle is disclosed. A high pressure gas flows through a first critical flow nozzle. Upstream of the first critical flow nozzle a small slip-stream of gas is removed and flows through a smaller second critical flow nozzle. The small second critical flow nozzle drops the pressure of the gas to a low level. This flow rate of this low pressure gas stream is measured in a highly accurate low pressure gas flow rate measuring device. Since the flow rate in this device must be the same as that of the second critical flow nozzle, a correction factor can be calculated for the second critical flow nozzle. This flow rate correction factor will be the same for the first critical flow nozzle.
