Excerpt from Orifice Meter Performance Downstream of a Tube Bundle Flow Conditioner, Elbows, and a TeeThe flow conditioner used for the tests was a 19-tube, circular pattern, in-line unit, as illustrated in figure 2. This type of flow conditioner is held in the pipe with a set screw positioned at the center of the tube bundle. The set screw was located at the top of the horizontal meter tube. The flange pressure taps were located at the 9 o'clock position looking in the direction of flow.The first objective of the test program was to determine the flow conditioner location where the calculated orifice discharge coefficient was equivalent to the discharge coefficient at the baseline. Four flow conditioner locations upstream of the orifice plate were selected. The closest was at seven pipe diameters because this is the minimum distance allowed[1] when using a beta ratio of The other locations were approximately 11, 17, and 27 pipe diameters. Data were taken using the meter with 46 pipe diameters of straight upstream pipe (the configuration shown in figure la) and with four orifice plates with beta ratios of and with the flow conditioner at 27 pipe diameters and the beta ratios of and a second test configuration used an oversized (6-inch) Sprenkle flow conditioner at 46 pipe diameters upstream of the orifice plate (the configuration shown in figure 1b).About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
