ABSTRACT:
A split flow mass flowmeter transducer in which measuring the rate of fluid flow through the meter is obtained via a thermal signal from a locally heated sensor tube that affords a parallel fluid flow path about the primary flow path through the main meter body. Enabling the measurement signal to respond more rapidly to changes in flow rate is a thermal shunt bridging the heated portion of the sensor tube for substantially equalizing tube temperature at predetermined locations upstream and downstream thereof.
