Water-Cone Flow Meter

McCrometer’s Wafer Cone’s new direct mount configuration minimizes installation labor while ensuring accuracy. Direct mounting the transmitter eliminates impulse lines, which not only lowers installation costs but also reduces potential leak points by more than 50 percent. Simple plug-and-play mounting ensures the meter is installed correctly the first time and eliminates a potential source of flow measurement errors. 

The Wafer-Cone Flow Meter is ideal for gas or liquid service in line sizes from 1 to 6 inches. The meter’s flangeless design makes installation fast and easy, while the interchangeable cone offers flexibility to accommodate changing flow conditions without the need for recalibration. When flow conditions change over time, the cone can be removed and replaced with a cone at a different beta ratio eliminating the need to buy a new meter. 

Space-saving and field-proven, the Wafer-Cone Flow Meter can be installed virtually anywhere in a piping system or be easily retrofit into an existing piping layout. No moving parts, virtually no maintenance, and an economical price make it ideal for applications including: natural gas wellheads, CO2 and water injection, gas lift, compressor anti-surge, fuel gas, separator discharge, biogas reactors, cooling systems, plant HVAC, process gas lines, and more.

The product’s design features a centrally-located cone inside a tube, which interacts with the fluid flow and reshapes the velocity profile to create a lower pressure region immediately downstream.  The pressure difference exhibited between the static line pressure and the low pressure created downstream of the cone can be measured via two pressure sensing taps.  One tap is placed slightly upstream of the cone and the other is located downstream of the cone.  The pressure difference can then be incorporated into a derivation of the Bernoulli equation to determine the fluid flow rate.
