Abstract
Single tube Coriolis flowmeter with floating intermediate section including an elongated upstream inlet conduit section, an elongated downstream outlet conduit section laterally offset from the inlet conduit section, an inlet-outlet plate rigidly connecting the inlet and outlet conduit sections together at their proximate ends, and a continuous and generally helically wound length of conduit (approximately a 720-degree coil), the ends of which are respectively continuations of the inlet and outlet conduit sections. The helically wound length of conduit includes an upstream metering loop section and a downstream metering loop section joined together by a 'floating', unsupported intermediate conduit section. The upstream ends of each metering loop section are coupled by a first connecting plate, while the downstream ends of each metering loop section are coupled by a second connecting plate. The otherwise unsupported intermediate conduit section extending between the first and second connection plates connects the upstream metering loop section outlet to the downstream metering loop section inlet. The intermediate section and the inlet-outlet plate are not connected to each other and are free to move relative to one another. The driver-oscillator device(s) is mounted between the two loop sections to impart equal and opposite exciting forces to the loop sections and the sensors are mounted between the loop sections to detect Coriolis force induced responses to the excited loop motions.
