Water Leak Early Warning: Night Flow Doesn't Lie

Argus EMS monitors night base flow with M-Bus water meters: flow that continues while the building sleeps is a suspected leak. Automatic alarms catch water costs before they burst your budget.

The Problem

A Leak Stays Invisible Until the Bill Arrives

A cracked underground line, a constantly running cistern, a valve forgotten open on the garden line — they can flow unnoticed for months. A water leak makes no noise and leaves no trace; it usually reveals itself only in a swollen water bill, and by then the cost has already been paid.

Argus EMS reads M-Bus water meters continuously and watches the most reliable signal: night base flow. Flow that never stops while the building sleeps is reported as a suspected leak through the alarm engine.

The Argus Solution

What Does It Provide?

Night base flow analysis — flow check during the building's quietest hours
Automatic suspected-leak alarms on continuous flow and flow jumps
Separate metering per block / line / unit
Exemption of legitimate night consumption (tank filling, irrigation)
m³ loss converted to cost via the tariff — the leak's price tag
Water reported on the same platform as electricity and gas

What Is Leak Detection via Night Flow?

The night flow method monitors water meter flow during night hours when consumption naturally approaches zero: flow that persists in these hours is most likely a leak. Argus EMS runs this analysis automatically every night and raises a suspected-leak alarm once the persistence condition is met.

Who Is It For?

Malls, hospitals, hotels and campuses with extensive plumbing networks
Property managers whose water bills rise without explanation
Facilities with underground lines or garden irrigation
Businesses that allocate water costs to tenants

FAQ

Frequently Asked Questions

How is a water leak detected?

During the quietest night hours (roughly 02:00–05:00) consumption is expected to be near zero. If the meter shows continuous flow in these hours, a base-flow suspicion forms; once the persistence condition is met, a suspected-leak alarm is raised.

Which water meters does it work with?

It works with M-Bus and Modbus communicating water meters; existing mechanical meters can be made readable with a pulse or M-Bus module. Meters per block, line and unit are monitored separately.

Are there false alarms?

Legitimate night consumption such as tank filling, irrigation or cooling tower make-up is learned per facility and exempted. The alarm opens not on a single reading but when persistence and threshold conditions are met together.

How quickly is a leak detected?

Large sudden leaks trigger a flow-jump alarm within the same day; small seepage-level leaks appear at the latest in the next morning's night base flow evaluation.
