V Cone Flowmeter
The V-cone flowmeter is a new type of differential pressure flow measuring device with a pointed cone coaxially installed in the measuring tube as the throttling part. It is a new type of throttling device based on the measurement principle of the venturi tube and integrating the advantages of the classic venturi tube, annular orifice plate and wear-resistant orifice plate.
Key Benefits
- Lower sensitivity than orifice plates and Venturi tubes to installation effects
- Shorter installation lengths, and maintenance-free or small workload.
- Less pressure loss than orifice plates
- It has the function of flow adjustment and mixing of fluids.
- Easy to install-it is an ideal flow meter for technical transformation.
- No stagnation zone, long-term stability
Product Description
The V-Cone is a differential pressure type flow meter with a unique design that conditions the flow prior to measurement.
- Differential pressure is created by a cone placed in the center of the pipe.
- The cone is shaped so that it “flattens” the fluid velocity profile in the pipe, creating a more stable signal across wide flow downturns.
- Flow rate is calculated by measuring the difference between the pressure upstream of the cone at the meter wall and the pressure downstream of the cone through its center.
Key feature:
- The upstream and downstream straight pipes are required to be short: the shortest upstream straight pipe length is 3D, (3D is required for the downstream installation of the valve), the downstream straight. The shortest pipe length is less than or equal to 3D.
- Accuracy: ±0.5%; repeatability is 0.1%; range ratio reaches 15:1.
- Dirt resistant and low pressure loss.
- It has the function of flow adjustment and mixing of fluids.
- Low pressure loss width range
- Signal stability
- Measurable high temperature, high pressure medium, and can measurable gas-liquid two-phase medium (moisture)
Application Range
The V-Cone Flow Meter is an advanced differential pressure instrument, which is ideal for use with liquid, steam or gas media in rugged conditions where accuracy, low maintenance and cost are important. V-cone flowmeter can be measured including:
- Water and wastewater industry
- Steam, air, natural gas, nitrogen, coke oven gas
- Chemical, plastics
- Food & beverage
- Oil and gas
- Pharmaceuticals, district HVAC
- Textile, etc
