Abstract: A method for eliminating false totalization in a flowmeter involves flowing a process fluid through flow tubes and vibrating the flow tubes with a driver positioned between a first and second pickoff sensor. The first pickoff sensor is closer to the inlet and the second pickoff sensor is closer to the outlet of the flow tubes. The method includes measuring the mass flow rate of the process fluid, totalizing the process fluid flow, and measuring voltages from the first and second pickoff sensors. A difference in amplitude of vibration greater than a predetermined threshold is detected between the inlet and outlet, indicated by the measured amplitude difference between the first and second pickoff sensor voltages. This difference signifies asymmetric damping due to uneven distribution of bubbles or solid particles. Consequently, the measured mass flow rate is set to zero, halting totalization and preventing false flow readings in a no-flow condition.
