Emerson Process Management”s Daniel ultrasonic flowmeter features diagnostic firmware and software with real-time monitoring and alarming capabilities that are designed to reduce measurement uncertainty and improve uptime. The software detects oil and gas flow disturbances that may affect measurement, delivers maintenance alarms prompting action to avoid failure, and provides an intuitive view of the meter health. The new firmware provides continuous flow analysis and generates actionable alerts to identify not only abnormal flow profiles, but also upstream blockage, deposit build-up within the meter, and the existence of liquid hydrocarbon in gas. The firmware also provides real-time AGA 10 Speed of Sound (SOS) calculations. These calculations reduce measurement uncertainty by comparing AGA 10 SOS calculations with the meter-calculated SOS. Significant differences in SOS can indicate possible upstream process upsets and can validate the integrity of the ultrasonic flow meter, gas analysis and analog measurements. The ultrasonic predictive alerts are generated by deviations from the initial baseline value of the meter. Baselines can be established at the calibration lab or upon initial start-up, triggering alarms to identify installation problems that can add to the uncertainty of measurement, and enable operators to avoid unscheduled downtime or process upsets. The diagnostics of Daniel ultrasonic meters can also be accessed via Emerson’s AMS Suite predictive maintenance software, which uses enhanced EDDL functionality to give a consistent, graphical presentation of information across Emerson’s intelligent field devices. Users can configure the ultrasonic meter online using AMS Device Manager or in the field using a 375 Field Communicator.
