ABSTRACT:
A coriolis-type mass flow meter is provided for use directly in a flow line. The meter has at least two straight flow tubes that have fluid flowing therethrough mounted with parallel axes. The flow tubes are vibrated in a direction normal to the flow direction and their axis by an exciting means at about 50% of their length. Detector means are spaced equidistantly from the exciting means (about 25% and 75% of the flow tube length) to detect the difference in phase between the upstream and the downstream portions of the flow tube relative to the exciting means. The phase difference between the two detectors is proportional to the mass flow rate through the flow tubes.
