“…The main part of the water stream was flowing through a measuring pipe (6) (stainless steel with an inner diameter of D = 50 mm), in which a standard orifice with a coefficient β = 0.5 was installed. Dynamic pressure on the orifice was measured with the differential pressure transmitter APR 2000/ ALW (5) programmed with a measuring range of Δp = 2.4 kPa, at which the relative error is 0.15% of the base.…”

Standard orifice flowmeters are widely used in the chemical and energy industry. Therefore, it is essential to know how accurate the measurements made with these instruments are. The paper presents an estimation of measurement uncertainty of a liquid mass flow using the orifice plate. The authors will present the influence of ranges of the Reynolds number on the estimated uncertainty, obtained on the basis of simulation and laboratory experiments. The research was conducted for the central orifice in the Reynolds number 8,000 < Re < 21,000. The results of estimating the extended uncertainty of the measurement of water flow using simulation and experimental method, are convergent. The maximum difference in the extended uncertainty values of flow measurement for the simulation and experiment was 0.04.10-3 kg/s.
