Random Sample/In Service Sampling

Extensive reporting is available for random sample and periodic testing. This includes progress reports on what has already been tested and what remains, and detailed statistical analysis. A regulatory report, customized for each utility, most typically takes the test results from the sample and extrapolates to the full meter population. This is done by determining the standard deviation and then determining the nonconforming percentage.

The Random Sample module, sometimes referred to as the in-service testing module, is designed to manage the random and periodic testing of your installed meter population. Depending on the regulatory environment, utilities typically choose one of two methods to ensure the accuracy of the meter population.

These requirements may differ from regulatory agencies across the USA, so we will review your State’s PSC/PUC requirements to ensure the system can be configured to meet the regulations. Canadian utilities need to comply with Measurement Canada regulations.
