Standard Method of FLOW MEASUREMENT OF WATER BY THE VENTURI METER TUBE
|Publication Date:||3 October 1969|
This method covers the measurement of the rate of flow of water in pipelines using the Herschel Standard Venturi meter tube.
Venturi2 meter tubes are applicable for the measurement of industrial water llow and particularly for slurries or similar nonhomogeneous liquids containing large concentrations of suspended solids. Individually calibrated, the Venturi tube is used as a standard of measurement for acceptance tests on pumping and similar equipment. Pressure losses through Venturi tubes are less than for other primary flow measuring devices installed in pipelines. Thus, substantial savings in pumping power consumption can be realized by its use.
2 The principle of the Venturi meter was first stated in 1797 by JB Ventrui, an Italian, and was first applied by Clemens Herschel to the measurement of flow in pipes in 1887
