Effect of fluid pressure on Coriolis mass flowmeter's performance

This paper presents some tests which have been carried out on a commercial model of Coriolis mass flowmeter under medium-pressure conditions ( p > 15 bar), utilizing a primary standard flow calibration facility. The experimental results show that the fluid pressure affects the accuracy of the tested meter, which provides underestimated readings (i.e. negative errors). Finally, some diagrams which allow to correct the output signal (or the reading) provided by the tested meter (according to the operating fluid pressure) are also presented.
