Five advantages of V-cone flowmeter
One, wide range ratio
Because the cone can make the fluid flow field uniform, so the flow rate can be measured lower than that of the ordinary differential pressure flowmeter, that is, the lower limit of the range is lower than that of the ordinary differential pressure flowmeter, so the range can be expanded downwards, the turndown ratio can be 15:1, and the Reynolds number can be obtained. As low as 8000 can still maintain the signal line shape.
Second, long life
The fluid flows through the cone without sudden fluctuations, but becomes a boundary layer along the cone and guides the fluid away from the cone's back corner. This makes the cone angle unaffected by the unclean fluid, flow coefficient β rate. Can remain unchanged for a long time, and ensure long-term accurate measurement. Therefore, the meter can be used for a long period of time in a dirty environment, without regular maintenance and periodical verification (of course, regular maintenance and verification of the secondary meter is still necessary).
Pressure loss Small permanent pressure loss is lower than orifice flow meters, close to Venturi.
Third, the signal stability
Due to the differential pressure generated by the throttling element, it also causes eddy currents behind the element, so each differential pressure instrument has signal fluctuations, even if the fluid is stable. For the standard orifice plate, due to the long eddy currents generated, it caused large-frequency signal fluctuations at low frequencies, which seriously interfered with the accuracy of the differential pressure readings. The V-cone-generated eddy currents are very short, so the signal fluctuations are high-frequency low. In the web, this makes the V cone produce a stable signal.
Fourth, a wide range of β value
The unique geometry of the V-cone allows a wide range of beta values, with standard beta values ​​of 0.45, 0.55, 65, 0.75, and 0.85, and
The beta value can be specified to guarantee the user's specific differential pressure output.
The V-cone purging design without stagnation area avoids the retention of residues, condensate or particles in the fluid.
Fifth, it can be used in a wide range of applications to measure dirt media without damaging the cones. Measure vapor-liquid two-phase flow (liquid phase does not exceed 5%) and guarantee accuracy
