Minimum Night Flow Monitor

/ Year

Quantify water loss and prioritize leakage repair efforts by analyzing Minimum Night Flow data.

The Minimum Night Flow (MNF) Monitor plugin transforms raw flow data into precise, actionable water loss insights. It accurately estimates potential leakage in your District Metered Areas (DMAs), helping you quantify Non-Revenue Water and monitor network performance. Prioritize maintenance efficiently by reviewing clear trend summaries and a dynamic list of zones, allowing you to focus resources on the most critical and impactful repairs.

Use Cases

Quantify Water Loss with Precision Automatically calculate the Minimum Night Flow (MNF) assuming a typical 70% factor to generate a data-driven, estimated leakage volume for your entire network and individual zones.

Prioritize Leakage Repair by Impact Quickly identify the zones that require immediate attention by ranking them based on the estimated leakage relative to the zone's total pipe length for efficient resource allocation.

Spot Leakage Trends Instantly Monitor the daily evolution of your DMAs with clear, color-coded summaries (Decreasing, Increasing, Stable) based on the past seven days' aggregated flow data to detect significant changes early.

Validate Field Actions After completing a leak repair or maintenance activity, use the plugin's trend analysis and historical graph to confirm the effectiveness of your action by observing a stabilization or decrease in the MNF.

Track and Validate Field Action Impact Review the MNF's "Evolution over time" graph to see if your repairs or network changes resulted in a significant and stable decrease in night flow, providing data-driven proof of your team's success.

Release Notes

Network requirements: Network must have defined zones (DMAs); Flow sensor in all inlets and outlets of a given zone; To calculate the Minimum Night Flow (MNF), we need flow readings that are valid for all inlets and outlets of the specified zone at the same time for any time between 12:00 AM (midnight) and 8:00 AM on the day of analysis.
