Multiple flow conduit flow meter

摘要

A multiple flow conduit flow meter (200) is provided according to an embodiment of the invention. The multiple flow conduit flow meter (200) includes a first flow conduit (201) conducting a first flow stream and a pair of first pickoff sensors (215, 215′) affixed to the first flow conduit (201). The multiple flow conduit flow meter (200) further includes at least one additional flow conduit (202) conducting at least one additional flow stream and at least one pair of additional pickoff sensors (216, 216′) affixed to the at least one additional flow conduit (202). The at least one additional flow stream is independent of the first flow stream. The multiple flow conduit flow meter (200) further includes a common driver (220) configured to vibrate both the first flow conduit (201) and the at least one additional flow conduit (202) in order to generate a first vibrational response and at least one additional vibrational response.

1. A multiple flow conduit flow meter (200), comprising:
a first flow conduit (201) conducting a first flow stream; a pair of first pickoff sensors (215, 215′) affixed to the first flow conduit (201); at least one additional flow conduit (202) conducting at least one additional flow stream concurrent to the first flow stream, with the at least one additional flow stream being independent of the first flow stream and with the first flow stream comprising a first material flow and with the at least one additional flow stream comprising a second material flow, wherein the at least one additional flow stream is independent of the first flow stream by comprising one or more of a different flow rate from a first flow stream flow rate, a different flow material from a first flow stream flow material, or a different flow material density from the first flow stream flow material density; at least one pair of additional pickoff sensors (216, 216′) affixed to the at least one additional flow conduit (202); and at least one common driver (220) configured to vibrate both the first flow conduit (201) and the at least one additional flow conduit (202) in order to generate a first vibrational response and at least one additional vibrational response, wherein the first vibrational response and the at least one additional vibrational response are usable to determine a first flow characteristic of the first flow stream and a second flow characteristic of the at least one additional flow stream.
