COMPACT VIBRATORY FLOWMETER FOR MEASURING FLOW CHARACTERISTICS OF A POLYPHASIC FLOW MATERIAL AND METHOD FOR BUILDING THE SAME

摘要

Compact vibratory flowmeter for measuring the flow characteristics of a polyphase flow material. A compact vibratory flowmeter (200) for measuring the flow characteristics of a polyphase flow material at a flow material pressure greater than about 10 pounds per square inch (psi) (69 kpa) is provided according to one embodiment. of the invention. the compact vibratory flowmeter (200) includes one or more flow ducts (301), at least two motion sensors (308) and a trigger (309) the compact vibratory flowmeter (200) also includes a maximum hydraulic transmission frequency at one. or more flow ducts (301) which is less than about 250 hertz (hz and an aspect ratio (l / h) of one or more flow ducts (301) which is greater than about 2.5 a height to gauge ratio (h / b) of one or more flow ducts (301) is less than about 10 and a curved flow duct geometry includes end bend angles of between about 120 degrees and about 170 degrees.
