摘要： A method and related ultrasonic meter identify and correct for transit time errors such as peak switch errors. The method includes calculating values for a set of diagnostics from measurements of the fluid flow, including transit time measurements. Based on the values for the diagnostics, and whether and how they fall outside of their respective ranges, the meter can identify a variety of problems with the meter or fluid flow, such as whether there has been an intermittent peak switch, a permanent peak switch, or the presence of noise, velocity pulsation in the fluid flow, temperature stratification, of other problem. In the event there is a problem with the meter, the meter self-tunes in order to minimize the chances of the problem happening again.

摘要： Methods and apparatus for a bi-directional dual chamber orifice fitting comprising a body with a chamber in fluid communication with a flow bore. The fitting also comprises an orifice supported by an orifice plate carrier that is selectably disposable in the bore. In the preferred embodiment, the lower chamber includes two passageways connecting the chamber to the flow bore. One passageway is located on either side of the orifice plate. Each passageway may also be equipped with a check valve to permit flow in only one direction through the passageway. In operation, the passageway on the upstream side of the orifice would allow fluid to flow into the lower chamber while the passageway on the downstream side would prevent flow back into the flow bore.

摘要： A method is disclosed to identify peak switching errors in an ultrasonic meter and how to correct for them. The method compares transit time measurements from two chords having different lengths to establish an error value. Depending on the magnitude and sign of the error value, any peak switching error can be identified and consequently corrected.

摘要： Methods and apparatus for operating an ultrasonic flow meter to accurately estimate the average flow velocity in a pipe when the meter has at least one failed chord and one non-failed chord. The method partitions the velocity range into a number of consecutive, non-overlapping “bins,” where separate bins are maintained for each chord and each flow direction. Each bin stores a chord proportion value and, in some embodiments, a chord velocity value. The bins are initialized with pre-selected values and, during normal operation, updated, or trained, based on the measured velocities. When a chord fails, and there is at least one non-failed chord, an estimated proportion value for each non-failed chord is generated using the values stored in the bins. The estimated average flow velocity is then calculated by dividing the summation of the measured flow velocities, from the non-failed chords, by the summation of the estimated proportions.
