V-Cone Meters

Like an orifice meter, a V-Cone meter is a differential type meter based on the principle of correlating the observed pressure drop due to an obstruction in the line to the volumetric flow rate. As the name implies, the obstruction is a V-shaped cone hanging in the center of the pipe (Figure 500-5). The size of the central V-Cone determines the beta ratio of the meter which is so defined as to have the same opening area as a same-size orifice meter at the same beta ratio.
