Flow meter for multiple conduits comprising a common vibration driver and pickoff sensors

摘要

A multiple flow conduit vibratory 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 and at least one additional flow conduit (202) to which are also attached at least one pair of pickoff sensors (216, 216'). The flow streams are independent of each other but are provided with a common driver (220) to vibrate both/all of the flow conduits in order to generate two or more vibrational responses.
