China Flow Meter-Differential Pressure Air Flow Meter Flowmeter Water Flowmeter

V shaped Flow Meter
What is V-shaped Flow Meter?
flow meter is a kind of differential pressure flow meter. It measures the flow rate through the throttling effect produced by V vertebral in the flow field. Compared with the average differential pressure flow meters, differential pressure flow meter has long-time high accuracy, good repeatability, less limitation of installation condition, lower abrasiveness, wider measurement range, more suitable for dirty medium, small pressure loss and so on.
The flow meter with V-shaped cone is widely used in various industries. Its excellent functions and features can measure high-temperature and high-pressure medium (the highest working temperature is 850 centigrade and the highest pressure is 42MPa); dirty medium( coke-oven gas, blast furnace gas, raw oil, residual oil and so on); gas-liquid two-phase medium( moisture and condensate water and so on). It is the best choice for industries like power, chemical, metallurgical, papermaking, environmental protection, petroleum and light and textile and so forth to measure the flow rate of gas and liquid.

Features of V-shaped Flow MeterLow installation requirement: 0 ~ 3D for upper stream and 0 ~ 1D for down streamTurndown ratio: 10:1Low pressure loss: pressure loss is just 1/3 ~1/5 of that of orifice plate for same βAbrasion resistance: vacuum will be produced after streamlined cone restriction, avoiding cone from wearing outNo block, no adherence: due to the contour of the V-cone not allow for area of stagnation where debris, condensation or particles from the fluid could accumulateExcellent repeatability: the V-cone primary element exhibits excellent repeatability of + 0.1%Long term stability: β ratio with no change for long term provide high accuracy for long timeSignal stability: signal fluctuation is 1/10 of that of orifice plateHigh accuracy: + 0.5%
