USM Performance monitoring

The world of fiscal metering, generally known as a reasonably “conservative” market, has focused on enhancing the metering accuracy for a very long time. Re-inventing the standards of the current existing metering principles was the way to achieve this enhanced accuracy. In an operating condition, to be sure the metering accuracy was still met, a regular maintenance check and/or recalibration of the metering equipment was required.

With the more recent developments in ultrasonic metering, a second aspect in fiscal metering accuracy was brought to light, i.e. it became possible to constantly monitor the meter performance in an online measurement.

In this way, the tools provided by the ultrasonic meter can provide the user with information on when maintenance, proving or a recalibration is really required, instead of using fixed time intervals. This information can be presented to the end-user in a stand-alone PC based program, or can be added to the standard functionality of the Supervisory Control System, both with all proper reporting capabilities to generate a log that can be used by the meter manufacturer for diagnostics and error tracing.

GSD is currently capable of handling performance monitoring for Ultrasonic meters of Elster-Instromet, Caldon and Sick-Maihak.
