A mass flowmeter comprises a first vibrating conduit (14) and second vibrating conduit (15) disposed in parallel, which combination is connected to a common inlet leg (16) and common outlet leg (17), and a combination of electromagnetic vibrator and motion sensor (20 and 21) that induces and measures the flexural vibrations of the two vibrating conduits (14 and 15). The mass flow rate is determined by comparing damping of the flexural vibrations of the first vibrating conduit (14) providing a flow passage to that of the second vibrating conduit (15) having zero net flow as it is blocked by a plug (18). |
