When metering the flow rate of fluid in a pipeline, it is most important that the flow approaches the orifice flowmeter in a normally turbulent state. When the approach piping of an orifice flowmeter is shorter than that recommended by JIS Z 8762, it leads to a noticeable error. Hence, the rectifying device investigated in the first report was tested for its ability to reduce the error. This device was installed just behind single, double, and triple bends. The effects of bent pipes on the discharge coefficient of an orifice flowmeter were examined, experimentally. It was found that this device could reduce the minimum required lengths of a straight pipe on the inlet side of the orifice flowmeter to a large extent without sacrificing its accuracy.
