High Performance V Cone Flow Meter Wear-Resistant And Self-Cleaning

Product Description

V-cone flow meter is a differential pressure type flow measurement device. So far it is more than 100 years since all kinds of flow measurement device that based on pressure differential theory been used. Pressure differential theory is based on energy conversion principle in sealed piping, means that to the steady liquid, flux and flow velocity's square root is direct ratio.

Working Principle:
V-cone flow meter is a differential pressure type flow measurement device. So far it is more than 100 years since all kinds of flow measurement device that based on pressure differential theory been used. Pressure differential theory is based on energy conversion principle in sealed piping, means that to the steady liquid, flux and flow velocity's square root is direct ratio. We know that pressure will reduce when velocity increase, when medium approaches to cone the pressure is P1, but when medium is passing to cone's throttled area, because passing area reduced, speed increased, pressure reduced to P2, both P1 and P2 are connected to differential pressure transformer through pressure mouth. When flow rate is changed, the pressure differential value will increase or decrease accordingly.

Features
1.Low installation requirement: Rectifying behavior changes the velocity distribution, eliminating the eddy current and blind space. upstream straight pipe 0-30D, downstream straight pipe 0-1D. 2. Turndown ratio : 10:1 (usually);50:1(maximum)
3. Small pressure loss and signal stability: V-cone differential pressure signal is high-frequency low-amplitude signals. When the same β value, the pressure loss is 1/3~1/5 of orifice plate's and signal fluctuation is 1/10 of orifice plate's.
4.Strong resistance against wear: After the streamline V cone is throttled, the vacuum effect will be generated on the surface of V cone to keep the V cone from being worn easily.
5.Automatic cleaning, no block, no adhesion: the complete purging design of V cone avoids the settlement of residue, coagulation or particle.
6.Long-standing favorable stability: the value of β can remain the same for long and the accurateness in measurement can be ensured for a long period.
7.High precision and good repeatability: accuracy:±0.5% F.S; repeatability:±0.1% F.S
8.Wide range of the value of β: the unique geometrical shape of V cone flow sensor allows wide range of the value of β.
9.Type specification complete, multi-choice of installation:pipeline, flange tapping, wafer and plug-in.

10.Wide range of nominal diameter: φ15~φ2000 (1/2"~120")or customize.
11.The ability to measure high temperature and high-pressure medium:maximum working temperature 700℃; maximum pressure 42MPa.
12.The ability to measure the dirty medium (coke-oven gas, blast furnace gas, feed stock and residual oil)
13.The ability to measure gas and liquid two-phase medium (moisture and condensed water)
