Anti-Surge Flowmeter Solution for Compressor Station

Compressor Station

Anti-Surge Flowmeter

To prevent the compressor from surging, a flowmetering device is placed in the compressor piping to monitor the gas flow through the compressor. For optimum compressor control this flowmeter has to always provide a precise, stable and reliable flow signal.

McCrometer’s patented V-Cone® Flowmeter’s unique design offers an advanced, differential pressure flow technology that acts as its own flow conditioner, fully conditioning and mixing the flow prior to measurement. The result is a low amplitude, high frequency signal with little “signal bounce.” Readings are always precise and reliable, including low pressure flow situations. The V-Cone offers an almost instantaneous response time and large turndown, which allows the compressor control to be fine tuned. This provides better results when using prediction control software and also helps simplify compressor installation construction due to the flowmeter’s inherent conditioning action. Another advantage is it’s outstanding performance without the upstream or downstream piping required by other flowmeters. This results in significant space and weight savings. For retrofit purposes, the V-Cone is simple to install. The V-Cone provides an accuracy from ±0.5% of rate and a repeatability of ±0.1%. It comes in sizes from 1/2 inch to over 120 inches. It handles flow turndowns up to 20:1. High pressure meters are available. Corrosion resistant models in most materials are also available.
