SIFAB AS is representing McCrometer in Norway. McCrometer is a US manufacturer of V-Cone differential pressure and electromagnetic flowmeters.

McCrometer V-cone Oil&Gas applications
Since 1955

V-Cone meters are supplied to a large number of applications offshore Norway. McCrometer develops innovative, high-quality, precision flow meters for the most demanding liquid, steam and gas measurement applications. 

V-cone meters can be taylor made to fit special applications and manufactured according to client needs and requirements. Short straight pipe requirements gives the V-Cone meter an advantage compared to other measurement principles. 

How does it work

High pressure port senses the line ( gauge) pressure of the process. The cone by reducing the free flow area, increase the velocity of the flow and as result create a discharge pressure that is lower than line pressure. The Low pressure port senses the discharge pressure, so across the High and Low Pressure ports, a Differential pressure (DP) can be sensed. Such DP is a direct measurement of the Volumetric Flow inside the pipe.
