V-Cone flowmeter with differential pressure transmitter


 

v-cone flowmeter and differential pressure sensor

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

V-Cone differential pressure flowmeter is a process control and multifluid meter that provides accurate, repeatable and cost optimized measurement solutions.
Designed to work in unprocessed and processed applications, the V-Cone flowmeter is ideal for : upstream, midstream and downstream oil and gas applications that present a wide range of measurement challenges.

The V-Cone flowmeter strengthens capability to provide the best solution for any measurement situation.

Measurement principlev-cone flowmeter and differential pressure sensor Measurement principle

When a cross sectional area of a closed conduit (or pipe) is reduced by a diametric change or by the use of a differential producer element, the velocity of fluids passing through the conduit are increased across the boundary change area (continuity equation). Pressure decreases (Bernoulli equation) and a differential pressure is generated across the reduction or producer.

While this principle is used by other differential pressure flow meters, The V-Cone flowmeter generates a differential pressure by creating an area of reduction using a cone-shaped flow element located on the center line of a pipe section as opposed to a reduced diameter pipe wall or orifice.

The differential pressure is measure using a differential pressure transmitter.
