McCrometer”s Wafer-Cone flowmeter is designed to provide accuracy, versatility and low maintenance in the smaller line sizes utilized for natural gas wells. Unlike most flowmeters that require a straight pipe run of 10 or more diameters upstream from the meter and 0-5 diameters downstream, the Wafer-Cone is designed in such a way that only 1-3 upstream diameters and 0-1 downstream diameters of straight-run are necessary. The flowmeter is designed for gas or liquid service in line sizes from one to six inches — ideal for natural gas wellheads, small process lines and many other plant infrastructure tasks. Other applications include burners or ovens, cooling systems, HVAC, etc. Provides accuracy of +/-1.0 percent, with a repeatability of +/-0.1 percent. It operates over a flow range of 10-to-1.
