V-cone Flow meter

V-cone Flowmeter, the unique structure of  V-cone flowmeter, fluid in the pipe doesn’t sharply contract, the change of fluid pressure is stable, and differential pressure signal is more stable, to ensure accurate measurement of flow, especially small flow.

  • Low sensitivity to installation effects.
  • The installation period is short.
  • Reduced pressure loss.
  • Effective for wet gas flow measurement applications.
  • Ideal for liquid, vapor, or gaseous media under harsh conditions.

 Because of the unique structure of the V-cone flowmeter, fluid in the pipe doesn’t sharply contract, the change of fluid pressure is stable, and differential pressure signal is more stable, to ensure accurate measurement of flow, especially small flow.

At the same time, because of the suspension of the axis and tapered body structure, when fluid is close to the V cone, pipe center velocity slows while velocity around pipe wall speeds. High-speed fluid directly washes the inner cone throttling element and pipe wall, automatically realizing cleaning, to avoid adhesion and accumulation of smudgy medium. It is applicable for liquid containing gas, a gas containing water, and gas or liquid containing solid. It has a unique advantage in the measurement of coke oven gas, blast furnace gas, natural gas, liquefied petroleum gas, high-viscosity crude oil, and smudgy.

The V-cone flowmeter is widely used in petroleum, chemical industry, natural gas, mining and metallurgy, steel, electric power, water, water supply and drainage, paper making, sugar processing, pharmaceutical, brewing, beverage, textile, printing, dyeing, chemical fiber, environmental protection, and municipal engineering industry measurement.
