Wafer-Cone Flow Meters are engineered for natural gas small line wellhead measurement. They are designed so only one to three upstream diameters and 0 to one downstream diameters of straight-run pipe are necessary.
Models precondition the flow profile to pass the cone in a uniform pattern for extremely precise gas flow readings without long straight pipe runs. For gas or liquid, 1 to 6-in. line sizes, Wafer-Cone is ±1% accurate with ±0.1% repeatability. It operates over 10:1 flow range
