The V-Cone® Flow Meter from McCrometer is an advanced differential pressure instrument designed for use with liquid, steam or gas media in rugged conditions where accuracy, low maintenance and cost are important. It is especially useful in tight-fit and retrofit installations.
The V-Cone® Flow Meter from McCrometer is an advanced differential pressure instrument designed for use with liquid, steam or gas media in rugged conditions where accuracy, low maintenance and cost are important. It is especially useful in tight-fit and retrofit installations.
The V-Cone flow meter relies on differential pressure (DP) technology. Unlike traditional DP instruments, such as orifice plates and Venturi tubes, the V-Cone flow meter’s flow conditioning function is built into the basic instrument. The V-Cone conditions fluid flow to provide a stable flow profile that increases accuracy. It features a centrally located cone inside a tube that interacts with the fluid flow and reshapes the velocity profile to create a lower pressure region immediately downstream.
The flow meter’s design is ideal for tight-fit and retrofit applications.
The pressure difference, which is exhibited between the static line pressure and the low pressure created downstream of the cone, can be measured via two pressure sensing taps. One tap is placed slightly upstream of the cone and the other is in the downstream face of the cone itself. The pressure difference can then be incorporated into a derivation of the Bernoulli equation to determine the fluid flow rate.
McCrometer’s V-Cone® Flow Meter is an advanced differential pressure instrument, designed for use with liquid, steam or gas.
The cone’s central position in the line optimizes the velocity of the liquid flow at the point of measurement. It forms very short vortices as the flow passes the cone. These short vortices create a low-amplitude, high-frequency signal for excellent signal stability. The result is highly accurate steam allocation from the stable flow profile that is repeatable for continuously accurate flow measurement.
