Illustrative scenario
Weekend ghost flow in an empty building
Illustrative scenario, representative of common industrial IoT applications
WaterFood & Beverage Processing
Water still running through an empty factory all weekend, worth about a fifth of the monthly bill.

How it went.
Every study on this site runs the same four beats, in the same order.
01
Alert
The factory shuts down Friday evening and starts up Monday morning. The monthly bill never showed what happened in between, because a month is not a resolution.
02
Cost
~20% of the monthly water bill. Consumed with the building empty, over a weekend.
03
Fix
Flow meter on the incoming water service · Sub-meters on the two largest consumers · Overnight and weekend baseline alerting
04
Restored
A weekend baseline that should read zero, and an alert when it does not

The problem
The factory shuts down Friday evening and starts up Monday morning. The monthly bill never showed what happened in between, because a month is not a resolution.
What would be installed
- Flow meter on the incoming water service
- Sub-meters on the two largest consumers
- Overnight and weekend baseline alerting
What changes
Before: A flat monthly number with no explanation inside it After: A weekend baseline that should read zero, and an alert when it does not
The number
~20% of the monthly water bill. Consumed with the building empty, over a weekend. Illustrative scenario, not a client result. Figure is representative, not measured.
In one line
A weekend trace should fall to a flat line. When it does not, the gap between the line and zero is money leaving the building with nobody in it.
