STUCK GAUGE

A stuck gauge refers to a sensor condition where readings remain constant over time, pointing to a potential malfunction. The typical root cause of this flat reading is the result of the mechanical float arm not moving within the tank or remaining stuck.

HOW ARE STUCK GAUGES DETECTED?

Tank readings are analyzed over a 7-day period to identify level changes less than 0.5%. The monthly consumption data of the tank is also analyzed for seasonal patterns (~18 months of data). The sensor issues and device abnormalities are extracted from the results. This provides clean results without other identified variables.

At a high-level, the algorithm to identify Stuck Gauges works as follows:

STUCK GAUGE RESULTS

When a Stuck Gauge event is identified, a new Maintenance Case is issued. The case is identified as 'medium' priority and labeled with the case type of 'potential stuck gauge'. The case is increased to 'high' priority if the initial case has been open for 5 days. Case is closed when issue is resolved or reading resume.

REPORTS:

Users can create reports for Stuck Gauge results by filtering the Case Types to display "Possible Stuck Gauge" and saving as a new report / download.
