flow meter for hydraulic testing

1.product information

V Cone Flowmeter is the newest high precision meter that can measure all kinds of Reynolds number. As well as can contentment all medium conditions, which required its operated principle as the same with others differential pressure type. Because of they are all based on principle of conservation of energy in the seal pipe. It has excellent performance as the one of kind structure.

2.Working principal

V Cone Flowmeter is a kind of differential type Flowmeter. With the differential principle design of flow meter has the application history of more than one hundred years. Differential Flowmeter was based on principle of energy conversion in seal pipe, that is for the stability fluid , Line pressure with the medium in the pipeline flow velocity is inversely proportional to the square root: speed increased while the pressure will decline. When medium is close to the cone, the pressure is P1, while when the medium through the cone’s throttling area, speed increased but the pressure will decline to P2.


3.1 V type cone Flowmeter is a kind of differential flow instrument; it was based on the principle of conversation of energy, if in the case of steady flow, pipe flow velocity and differential pressure in the direct ratio.

3.2 measuring stability is good, flow coefficient remain unchanged lasting for a long time.

3.3 high precision, good repeatability, can fulfill the accuracy measurement.

3.4 Widely measurement range, can reach to 10:1 without secondary instrument software correction.

3.5 Low requirement for straight pipe installation, small pressure loss.

3.6 The medium to be measured adaptability is strong, can measure the cleaning fluid, fluid containing solid grains, low pressure fluid, high humidity gas and all kinds of dirt fluid. Flow components with self-cleaning function, resistance to wear.

Measured Mediums

liquids, gases and steams (NOTE: the mediums should be unidirectional or can be

seen as unidirectional.)

When the dryness of saturated steams ≥85%, they can be seen as unidirectional.
