V Cone flow meter Selection table
How to choose V cone flow meter? V Cone flow meter selection table where there is free download? What are the manufacturers of V-cone flow meter? The differential pressure signal produced by V-Cone flow meter must be measured by differential pressure transmitter and then fed into flow-meter or flow computer for processing. For the temperature and pressure changes are too large or high measurement requirements of the medium, sometimes need to carry out temperature, pressure correction. Our company can provide these instruments, and can be programmed and calibrated before the factory.
The advantages of V-cone flow meter: 1. High precision: The precision of the cone flow meter is ±0.5%;2. Good repeatability: Better than ±0.1%;3. Low installation requirements: The flow meter before 0-3d straight pipe, 0-1d straight pipe can ensure the accuracy of measurement. The test results show that the cone flow meter can be close to the single bend or the double bend of different plane and has little influence on the precision. 4. Long-term stability: fluid flows through the cone without sudden fluctuations, but along the conical body formed a boundary layer, and guide the fluid to leave the posterior corner of the cone. This allows the cone angle to be unaffected by the abrasion of the unclean fluid. Beta rates can be constant for a long time, and ensure long-term accurate measurement. 5. Signal Stability: Every differential pressure meter has "signal fluctuation". This means that even if the fluid is stable, the signal produced by the throttle element has a certain amount of fluctuation. For the standard orifice plate, the vortex generated after the plane is longer, these long eddy current causes the orifice plate to produce the low-frequency large signal, the serious interference differential pressure reading accuracy, while the fluid flows through the internal cone type flow meter to form very short Eddy current, these eddy current causes the internal cone type flow meter to produce the high-frequency, the low amplitude signal, this causes the cone flow meter to produce the stable signal These two signal variations are shown in the diagram. 6. Low-voltage loss width range: Because there is no sharp edge, cone flow meter caused by permanent pressure loss is constant and smaller than the orifice plate. In all differential pressure flow meter, only the pressure loss of the inner cone flow meter is close to the venturi. At the same time, the extremely stable signal makes the differential pressure range lower than the general differential pressure flow meter, so the range can be extended to the lower limit, the usual amount of turndown 15:1, Reynolds number low to 8000 still can keep the signal linearity. If the curve correction is used, it is still measurable and can maintain good repeatability under lower Reynolds number conditions. Wide range of 7.β values: The unique geometrical shape of the cone flow meter allows for a wide range of beta values. The standard beta values are 0.450, 0.550, 0.650, 0.750, 0.850, and can be specific beta values to ensure user-specific differential pressure output (no increase in cost and no impact on delivery time). 8. Wide pipe range: Tapered flow meter has two basic forms, namely, pipe type and insert type. Its size from 15mm to 1600mm. 9. No stagnation zone: the cone-sweeping design avoids the residue, condensation or particle retention in the fluid.
