Interesting Facts About Differential Pressure Cone Flow Meters

Requirements for measurement of flow exist throughout the industrial process control field. The applications are varied and vast. As a result, there are a number of technologies available for flow measurement and an even larger array of manufacturers providing devices and instrumentation that can be used to measure fluid flow.

Selecting the measurement technology that will provide appropriate performance for a process measurement application is an initial challenge for every process design. In order to accomplish this task, it follows that a well rounded understanding of the potentially positive or negative attributes for each methodology is necessary.

Differential pressure is one method of indirectly measuring fluid flow. It measures the change in pressure created as media flows past an obstruction in the fluid path, which, when combined with other information and calculation can be used to derive a measurement of mass flow. Like all measurement methods, there are applications where this one excels over others and some where it may not be as advantageous as alternate methods.

One manufacturer of differential pressure flow measurement devices is McCrometer. The company has been manufacturing DP flow measurement devices for over thirty years and has over 75,000 installations worldwide. In the company’s own words, their flagship V-Cone product “is an advanced differential pressure instrument, which is ideal for use with liquid, steam or gas media in rugged conditions where accuracy, low maintenance and cost are important.”
