Differential Pressure Flow Meters

Engineers who rely on differential pressure meters gain a variety of valuable benefits, including:

• More reliable measurements – Differential pressure meters deliver accurate measurements, despite disruptive turbulence and a broad range of flow characteristics. They’re uniquely designed to maintain accuracy and consistency of readings, even in difficult or varied flow conditions.
  In fact, McCrometer’s V-Cone DP meter is self-conditioning, which helps it thrive in turbulent flow with minimal to zero straight-run requirements. This is in contrast to other DP meters that require somewhat clean, laminar flow in the line ahead of and beyond the flow meter, therefore removing the need for extended straight-run requirements.
• Minimal maintenance – Because V-Cone differential pressure flow meters push the flow to the outside of the pipe to create the pressure differential, there is little to no impact on the cone itself unlike the wear seen on orifice plates. Additionally, there is no risk of damming or clogging seen with other more restrictive DP flow measurement primary element designs. Less wear and tear means less need for recalibration and replacement supporting the 25+ year life expectancy for the V-Cone.
• Customizable solutions – There are many key aspects of DP meters that can be fully customized to fit customer requirements, such as turndown, total pressure loss, and valve size for optimized operability.
• Installation flexibility – Since V-Cone differential pressure meters are custom-built based on the parameters for the application (e.g., across filters, backflow preventers, and heat exchangers) and ready to install, it reduces both installation time and costs as well as improves overall productivity.
• Reduced footprint – DP flow meters are built to fit in a compact space and reduce the amount of piping that leads up to and away from the meter.
  That means spending less space and money configuring piping and support requirements without sacrificing accuracy. This also reduces any critical space and weight demands for platform-mounted applications.
• Low permanent pressure loss – Since differential pressure meters provide a consistent, even flow around transitions, they ensure less permanent pressure loss.

Many people believe cone meters only measure gas. They also measure steam and liquids in many industries including oil/gas, chemical, electric power, food & beverage, HVAC systems, metals and mining, pulp and paper, water and wastewater treatment, and more.

While it’s very common for cone meters to be called a V-Cone, McCrometer, Inc. invented and patented the first successful cone meter, the one and only V-Cone® flow meter, in 1985. Today, there are over 97,000 McCrometer V-Cone flow meters installed worldwide, and the total number continues to grow each year.

The V-Cone is designed for today’s most challenging oil & gas production, industrial projects, pulp and paper, mining and metals, food and beverage, pharmaceuticals, aerospace and more.

Gather flow process information (temperature, pressure, fluid properties, etc.) and pipeline characteristics (pipe schedule, end connections, line size, etc.) in order to get started. Once you’ve gathered all applicable data, you can utilize McCrometer’s V-Cone Sizing Tool. For additional information on the V-Cone Sizing Tool, visit the support page.
