General
Cone Flow Meters are designed to measure the volume flow of liquids, steam and gases according to the differential pressure principle. A conical flow element is placed in the centre of a pipe line, in which the fluid to be measured is passing through. With a tap in front (flow direction) of the flow element the pipe pressure (static pressure) is measured. Passing by the element, the flow velocity raises and generates an under-pressure behind the cone, where the second tap is located. The two measured pressure values are to be compared. The outcome is called “differential pressure”. With this differential pressure now the flow can be calculated.
