To support McCrometer’s European customers, the high-accuracy, virtually no-maintenance Wafer-Cone® Flow Meter meets the requirements of the European Community’s Pressure Equipment Directive (PED) 97/23/EC and is eligible for use throughout the region.
The PED standard was adopted by the European Parliament and the European Council in 1997. It provides standards for the design, manufacture, testing and the uniform assessment of equipment and assemblies operating in pressurized environments across the European Community.
CE Marking for all service categories under the Pressure Equipment directive (PED) 97/23/EC means that McCrometer’s European customers have third party assurancethat the Wafer-Cone Flow Meter is safe for use in the pressurized environments found in industrial processes and plants. The Wafer-Cone Flow Meter meets essential safety requirements covering design, manufacture and testing; satisfies appropriate conformity assessment procedures; and carries the CE marking and other information.
The Wafer-Cone Flow Meter is ideal for liquid, gas or steam service in line sizes from 1 to 6 inches. The meter’s flangeless design makes installation easy, while the interchangeable cone offers flexibility to accommodate changing flow conditions without 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 cost make it ideal for applications including: wellheads, gas, 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 Wafer-Cone Flow Meter’s unique differential pressure sensing technology with built-in flow conditioning greatly reduces the required straight pipe run for installation as compared with technologies such as orifice plates and Venturi meters. The Wafer-Cone meter is highly accurate and requires of straight run of only 1-3 pipe diameters upstream and 0-1 pipe diameters downstream to ensure measurement reliability. Its ability to self-condition flow makes it a space-saver, allowing for a reduction of the instrument overall footprint and weight.
The Wafer Cone Flow Meter’s built in flow conditioning and resulting stable flow profile achieve an accuracy of +1.0 percent, with a repeatability of +0.1 percent, and operates over a flow range of 10:1. The Wafer Cone Flow Meterraises the bar for economy, ease of use and performance.
The Wafer-Cone‘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.
The Wafer-Cone’sdirect mount configuration minimizes installation labor while ensuring accuracy. Direct mounting the transmitter eliminates impulse lines, which lowers installation costs and reduces potential leak points by more than 50 percent. Simple plug-and-play mounting ensures the meter is installed correctly and eliminates a potential source of flow measurement errors.
