“…Many investigations about the cone performance have been carried out and they are aimed at evaluating the influences of the flow conditions on the cone discharge coefficient. In Borkar et al (2013) and Singh et al (2006), the authors have shown that the C d factor is quite independent of the Reynolds number for fully developed turbulent flow, and it is nearly independent of the V-Cone diameter ratio β. In addition, the overall performance of the cone is not heavily influenced by any disturbance upstream (due to elbows, throttles, valves, etc.…”

“…In this section, the authors perform a detailed analysis of the permanent pressure losses induced by both cone geometries. The permanent pressure losses have been defined as the percentage of the pressure drop (measured at the static pressure taps) induced by the obstruction (Figliola and Beasley, 2010;Miller, 1996). The insertion of the flowmeter within the flow increases the fluid dynamic loss (usually due to the friction effect at the wall) because of the turbulent kinetic energy dissipation occurring just beyond the flowmeter, as has been pointed out in the energy balance check section.…”

Differential pressure flowmeters are commonly used in industrial applications where, however, the upstream flow conditions are usually highly disturbed, caused by the presence, in the network pipe, of elbows, valves, etc. To achieve accurate flow measurements, the use of the cone meter is recommended as the flowmeter has the property to normalize the flow both upstream and downstream. In this paper, the authors present a cone flowmeter of new geometry that allows them to obtain better performance with respect to the original one; in particular, it provides a higher discharge coefficient (C d ) for a wider range of operating conditions.

“…Hollingshead et al 5 studied the Venturi, V-cone, and wedge flow meters at low Reynolds numbers and discovered that the discharge coefficients’ rate of decrease was higher with a decreasing Reynolds number. Borkar et al 6 explored a novel pressure-averaging technique to enhance the performance of the cone flow meter for measuring flow disturbance. Singh and Tharakan 7 simulated the flow in the single-hole and multi-hole orifice meters and discovered that early reattachment of flow in the multi-hole orifice meter could reduce the pressure loss.…”

The swirl meter is one of the gas flow meters used in the industry. Its advantages are as follows: a strong signal level, easy maintenance, and stable performance. Hence, it has become widely accepted for natural gas metering. In this study, the numerical computation of the three-dimensional unsteady flow in a swirl meter was conducted using the renormalization group k–ε turbulence model and SIMPLE algorithm. The internal flow fields were analyzed in detail, wherein the velocity and pressure distributions were discussed under six flow rates (6, 15, 25, 40, 70, and 100 m3/h) and three swirl cone angles (11°, 20°, and 30°). The obtained results are reported and discussed as follows: the stable performance of the swirl meter was due to its capacity to maintain its internal characteristics over a large flow range. Also, it was detected that though the pressure decrease was gradual on the wall, an opposite tendency was shown at the center. On the other hand, the swirler structure was crucial to the metering capacity of the swirl meter, and the swirler cone angle influenced the pressure and velocity.

“…Other technologies such as ultrasonic [9,[16][17][18], electromagnetic [18][19][20] or multi-hole orifice [21] flow meter have been simulated to analyse the influences of upstream perturbations. Despite its wide use, even with other hydraulic accessories and water meters [20,[22][23][24], research on precision of Woltman meters operating with hydraulic flow regulating elements, such as gate and butterfly valves, is scarce.…”

One of the unknowns in the instrumentation for water measurement is what degree of influence other hydraulic elements exert on the velocity profile and, consequently, on the measurement errors. In this work, the measurement errors of a horizontal-axis Woltman meter produced by a gate valve and by a butterfly valve in different hydraulic configurations were studied using a simplified numerical model. The gate valve was installed beside the meter and three pipe diameters upstream of the meter and were operated with closures of 75%, 50% and 25%, while the butterfly valve was installed at three pipe diameters upstream of the meter with closures of 0 • (open) and 30 • . The numerical model based on the rotor's torque balance equations and Computational Fluid Dynamics (CFD) was validated by experimental tests. According to the results, it was concluded that the proposed model is valid and capable of estimating the errors caused by the hydraulic fittings arranged next to the meter. In addition, it is evident that for the analysed operating range, both valves must be installed at least three diameters of straight pipe upstream of the meter.
