A unique measurement solution due to the hydrodynamic V shape of the cone.
 

The V-Cone® flowmeter reinforces our ability to offer the best flow measurement solutions for any situation you may encounter.

It is the ideal solution for accurately measuring the flow of fluids in your pipes.

The V-Cone® flow meter is capable of measuring a variety of fluids including water, oil, gas, steam and condensate. With its innovative centre cone, the V-Cone provides accurate real-time flow measurement.

The V-Cone® is also capable of measuring fluids containing suspended solids or fibres, making it a valuable tool for industrial applications such as food and beverage, mining, chemical, oil and gas, and many more.


 

Benefits of the V-Cone® flow meter

The V-Cone® offers many advantages over other types of flowmeters, such as its ability to measure high temperature and high pressure fluids, and its low sensitivity to installation conditions. The V-Cone® is also easy to install, as it does not require straight lengths of pipe upstream and downstream to provide an accurate measurement.

  • Proven performance. Today, there are over 75,000 V-Cone® flowmeters installed worldwide.
  • Excellent repeatability
  • High accuracy
  • High dynamic range, capable of measuring both low and high flow rates
  • High performance in harsh applications.
  • Designed for light to harsh operating environments, this state-of-the-art flowmeter consistently outperforms traditional differential pressure (DP) devices and other flow technologies
  • Maximum installation flexibility. Can be installed virtually anywhere in the piping system, or easily retrofitted to an existing piping system, resulting in significant cost savings.
  • Low or no operating costs. Guaranteed long-term performance with no moving parts to replace and maintain.
  • Long durability for superior value.

 

Measurement principle of the differential pressure cone flow meterv-cone flowmeter and differential pressure sensor Measurement principle


The operating principle of the differential pressure cone flowmeter is based on the use of Bernoulli's equation to measure the flow of a fluid through a pipe. Bernoulli's equation determines that the pressure drop across the constriction is proportional to the square of the flow rate. The differential pressure cone flowmeter has a cone-shaped element that shapes the flow before the differential pressure measuring connection, without influencing the flow with a sharp surface, which makes possible an extremely stable signal for the measurement and minimal wear on the conical side.

The V-Cone® flowmeter generates a differential pressure by creating a reduction zone through a cone-shaped element located on the central axis of the pipe.

The differential pressure cone flowmeter measures the pressure difference between two points in a pipe where fluid is flowing. As the fluid passes through the cone, the cross-sectional area of the pipe narrows, causing the fluid velocity to increase. This increase in fluid velocity causes a decrease in the static pressure of the fluid in that area.

As the fluid passes through the cone, the cross-sectional area of the pipe narrows, causing the fluid velocity to increase. This increase in fluid velocity causes a decrease in the static pressure of the fluid in that area.

The pressure difference between upstream and downstream of the cone is measured by two pressure taps located upstream and downstream of the cone. The pressure difference is directly proportional to the fluid flow rate in the pipe. The pressure difference is measured by a differential pressure transmitter that converts the pressure difference into a linear electrical signal that is proportional to the flow rate.
