Diesel generator monitoring: fuel, runtime and theft alerts.
See the fuel level, runtime and refills of every genset from one dashboard. Low-fuel alerts before an outage, drain alerts within 60 seconds, on any remote site.
What you have today
Genset tanks get forgotten until they run dry and the power goes out, or until someone notices the fuel bill doesn't match the runtime. Remote sites are worse: by the time a service truck arrives, the outage has already cost more than the fix.
What we add
A DUT-E sensor reads the tank to ±1%. A GSM head or your BMS pushes the data every minute. Refill-soon alerts at 25%, critical alerts at 10%, theft alerts within 60 seconds of an unauthorized drain, by SMS, email or webhook. Add a DFM flow meter on the engine to measure real consumption per hour and catch an overloaded or failing generator early.
Every refill, every runtime hour, every drain event - on one timeline.
Once installed, fuel level and runtime stream to your dashboard at a configurable interval. Refill events, drain events, and projected empty time are surfaced automatically.
- Fuel-level curve - natural draw-down during runtime with a forward projected-empty indicator.
- Refill spikes - exact volume and timestamp, reconciled against fuel-vendor receipts.
- Drain events - sudden drop with no runtime triggers an alert with location, volume, and timestamp.
Pick the configuration that fits your site setup.
Most operators standardize on standalone GSM. Sites with an existing building management system integrate over RS-485 instead.

Drops into your existing monitoring stack.
Wagencontrol hardware speaks RS-485, Modbus, and cellular protocols so data flows into your existing platform or BMS dashboard.
Operators running this setup in the field.
DUT-E sensors on stationary genset tanks alert operators before fuel runs out - preventing power loss in conflict zones.
Regional backup gensets were connected to one dashboard and refill scheduling moved from calendar-based to consumption-based.
DUT-E with GSM across remote towers sends SMS alerts within 60 seconds on any drain event outside runtime.
