Gas turbine flowmeter measurement of pulsating flow
A theoretical analysis of a gas-turbine flowmeter in the measurement of pulsating flow, including both fluid drag and nonfluid drag on the rotor system and dealing with pulsating flow of arbitrary wave shape, appears to be validated by a wide range of test results except for a large pulsation index where the situation is more complex and needs further investigation. The meter pulsation error of a gas-turbine flowmeter may be estimated with reasonable accuracy for a known pulsating-flow situation using steady-state values of fluid drag and nonfluid drag. Test results indicate a gas-turbine flowmeter retains its excellent steady-state repeatability in pulsating flow, which is a necessary condition for possible measurement of pulsating flow. The results of the analysis provide basic information for the increased understanding of turbine flowmeter behavior.
