Product Introduction 

V-cone flowmeter is a NEW type Throttling Device which have the advantages of Classical venturi tube and circular orifice. It follows the law that in closed conduit the energy is conserved- Berylliumnoulli Equation and Flow Continuity Equation, in the condition of steady flow, the flow speed of the conduit is proportional to the square root of the differential pressure. The V-cone flowmeter has many characters: good stability, accurate high pressure, good repeatability, wider measure radio, low requirement to the installation pipe and low pressure loss, it can test the fluids which contain solid particles,low pressure fluids,high humidity gas and other dirty or pollute fluid.

Application Selection Guide:

 It is widely used in the industry of petroleum, Chemical and Natural Gas. Compared with the Standard plate, venturi tube and nozzle Throttling Device, it overcome the drawbacks such as easy to wear, high pressure loss, small measure radio, high requirement of installation, required longer straight pipe etc. and it can give a very exact measurement result to many kinds fluids in a widely range of Reynolds. The very important virtues of the V-cone flowmeter compared with ordinary flowmeter are higher accuracy, longer time stability, better repeatability, and lower limit by the installation conditions, better wear resistance, wider measurement radio, proper to dirty or pollute object, less pressure lose, longer usage life etc. It is widely used in many fields, proper to test water, oil, various liquids, steam, gas, natural gas, petroleum gas, organic gas, oil residue etc.
