Excerpt from Flow Conditioner Location Effects in Orifice FlowmetersTests sponsored by Gas Research Institute were conducted with orifice flowmeters of two nominal sizes: 104 mm (4 in) and 52 mm (2 in). For the 104 mm orifice meter we compared discharge coefficients measured in two common piping configurations used by laboratories to establish baseline flow conditions. The discharge coefficients are similar for beta ratios of and but not for the beta ratio plate. For other tests with this orifice meter, a 90° elbow or a reducer was located upstream of the orifice plate and flow conditioner. Two beta ratios were tested in the 52 mm orifice meter in baseline configuration and with an elbow at 170 and a flow conditioner at 120. For many of the tests, differential pressures were measured at.more than one flange tap location. Placing the flow conditioner too close to the orifice plate in either meter yields discharge coefficients below baseline values The location of the flow conditioner with respect to the orifice plate appears to influence meter performance more significantly than the type or location of flow' disturbance upstream of it, With larger beta ratio plates, the flange tap location affected the value of the discharge coefficients.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
