Abstract: Ultrasonic meters have been used in ga s custody transfer measurement worldw ide for over 25 years with varying degrees of success. Initial attempts proved unstable and ma intenance intensive, this was contrary to the initial expectations which foresaw a device with little or no obs truction, limitless turndown and little to no required maintenance. The advent of higher speed, more robust el ectronics enabled the use of digital signal processing which eliminated the need for analog threshold levels and the constant problem of peak skipping and lost timing. The improved electronics also enabled the implementation of large internal logs, advanced diagnostics, improved communications and overall stability, all of which increased user confidence in the ultras onic technology.
