Test Stand for Studying Flowmeter Performance in Presence of Pulsatile Flow
Maciej Szudarek , Mateusz Turkowski , Grzegorz Twaróg
AbstractPulsatile flows are commonly found in industrial conditions and they can severely impact measurement uncertainty. For that reason their influence has been studied for the most widely used flowmeter types. However, there are topics that require further investigation. The presented test stand allows generating sinusoidal pulsatile flow with variable flowrate component up to 14 m3/h and frequency up to 20 Hz. Bell prover is used as a flowrate reference and allows achieving mean volumetric flow rates up to 65 m3/h. Pulsation parameters are obtained by means of spectral analysis of data registered by constant temperature anemometer. Capabilities of the constructed stand are presented on the example of mechanical oscillator flowmeter. Lock-in phenomenon has been studied in the intermediate range of dimensionless pulsation parameter. Maximal values of relative errors have been found for various pulsation amplitudes.
