The discharge coefficient is reported for a flowmeter based on a segmental wedge device having a vertex angle of 90 degrees for varying ratios of pipe diameter D to characteristic free flow dimension H at the wedge. The current work suggests that the segmental wedge makes a reliable flow-metering device, with a near constant discharge coefficient over a wide range of Reynolds numbers. A correlation is provided for the discharge coefficient as a function of HID.
