Abstract:
The paper shows the development of an elbow flowmeter for the measurement of flow rate in sewage pumping
facilities. The paper describes the results of laboratorial tests, the use of a special pressure transducer for the
measurement of the difference in centrifugal force in the pressure taps of the elbow and, finally, the field tests
in a sewage pumping facility. Results show that for Reynolds numbers greater than 105 the K coefficients are
constant within ± 1% and follow the theoretical curves within ± 0,5%. The uncertainty in the measurement of the
flow rate was determined to be better than 2%.
