Differential Pressure Flow Measurement in Wet Gas

The measurement of wet gas flow is important due to the increased use of hydraulic fracturing, also called fracking, to release gas deposits. The many wells created using this method for gas production have encouraged the development of methodologies to compensate for the presence of fracking fluid and other liquids that come out with the gas. While a separator can be used to remove the liquids from the gas, the size and cost of these devices prevents their use for production purposes. Traditional orifice plates have an option for a drain/vent hole that is drilled into the plate at the pipe wall to pass liquids. If liquid buildup is collecting at a higher rate than the hole can pass, the plate becomes a dam and the collecting liquid changes the pipe area which can affect the performance. The Rosemount Conditioning Orifice Plate can avoid this problem if the plate is oriented with one hole at the bottom of the pipe. In this orientation, the collection of liquids is greatly reduced.
