Benefits of the V-Cone® flow meter

advantages of the vcone 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.


Measurement principle of the differential pressure cone flow meter

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.

operating principle of the differential pressure cone flow meter

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.

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.
