Precise fuel control with detection of drains and theft

cloudGPS analyses fuel-level sensor (DUT) readings in real time and automatically classifies "Refuel", "Consumption" and "Drain" events. Multi-tank and multi-reservoir support on a single device. Works with Teltonika, Bitrek and other trackers supporting Wialon Retranslator and Teltonika Codec 8/8E protocols.

Why standard GPS monitoring isn't enough

Basic systems just show the fuel-level chart. cloudGPS automatically distinguishes a refuel from a drain, handles multiple DUTs on one device, tracks water in tanks and correlates data with mileage and engine running time.

local_gas_station

Refuel tracking

Automatic detection of "Refuel" events tied to location, time and volume. Reconciliation with petrol station data or fuel card transactions.

warning

Drain detection

FuelAnalyzer distinguishes normal engine consumption from sudden level drops. The minDrainVolume parameter is tuned to your equipment.

water_drop

Water-in-tank control

Support for a separate water sensor or a magnetostrictive DUT with two floats (fuel + water). The platform analyses both channels together and sends an alert when the water level exceeds the limit — saves your pumps and your customers.

stacked_line_chart

Multiple DUTs per device

A combine or tractor may have 2-3 tanks. Each DUT is analysed independently — events don't get mixed up between tanks.

Ready-to-use reports

FuelReport, TanksReport — PDF/Excel reports for the period. Level charts, event tables, per-tank balance, export for accounting.

notifications_active

Real-time alerts

Telegram/email notifications for suspicious drains, low fuel, water excess. A 10-minute buffer prevents false positives.

Who this works for

Three segments where fuel control delivers the biggest effect — from a combine in the middle of a field to a 60 m³ depot tank.

agriculture Agricultural fleets

Combines, tractors, sprayers — machines with 1-3 tanks, operating far from the office. Often the target of drains or "side" refuels.

Per-tank control (multi-DUT)
Drain detection during standstill
Consumption-per-hectare report
Refuel binding to field fuel stations

local_gas_station Fuel depots and storage

5-100 m³ tanks with multiple DUTs and water sensors. Large volumes where an accounting error is costly.

Hauling cargo through Poland? PUESC and e-TOLL — built in

Polish SENT-GEO law requires automatic position transmission for fuel, tobacco, alcohol and other sensitive goods. e-TOLL is the mandatory toll-payment system for vehicles over 3.5 t. cloudGPS covers both requirements with no extra hardware.

✓ Registered OUL/ZSL provider in Polish state registries
✓ Data transmission from your existing tracker (Teltonika, Bitrek, etc.) — no OBU purchase
✓ Guides for self-registration at puesc.gov.pl and etoll.gov.pl + support
✓ Transmission toggle — one click per vehicle, no tracker reboot

How it works

cloudGPS is a server-based monitoring platform. Hardware installation and initial calibration are done by a certified installer (yours or from our partner network). The platform picks up the data as soon as the device is connected.

Installation and calibration

The installer mounts the DUT in the tank/reservoir, connects it to the tracker (Teltonika, Bitrek or other compatible) and performs the "litres ↔ DUT readings" calibration. We have a partner installer network.

Connecting the tracker to cloudGPS

The tracker sends telemetry to the cloudGPS server. The calibration profile is stored in your account. Adding a new tracker takes a few minutes in your dashboard.

The platform analyses readings

FuelAnalyzer on the server processes the data stream: filters noise, applies tank-specific parameters (minDrainVolume, minRefuelVolume and others), classifies events. You tune the parameters in the web UI.

You get events and reports

"Refuel", "Consumption", "Drain" appear automatically. Charts, PDF/Excel reports, Telegram alerts — all available in the browser and mobile app.

cloudGPS vs basic GPS monitoring

Standard systems show only a chart. cloudGPS analyses events and detects what you wouldn't spot on the chart yourself.

Frequently asked questions about fuel control

Everything you need to know before deployment — from DUT accuracy to PUESC integration.

How accurate is fuel-level measurement?

It depends on the DUT and calibration quality. For typical capacitive DUTs (Omnicomm LLS, Mechatronics, Technoton) accuracy is ±1-2% of full volume. For depot tanks with calibration tables — ±0.5-1%. cloudGPS doesn't improve the sensor physically, but its smoothing algorithms filter noise from fuel slosh during movement.

Can I connect more than one DUT to a single device?

Yes. Depends on the tracker model: Teltonika FMC650 supports up to 3 RS-485 DUTs, Bitrek 810 — up to 4. cloudGPS analyses each DUT separately (multi-DUT) and never mixes events between tanks. This is critical for combines and fire trucks with 2-3 tanks.

What is a "Drain" and how do you detect it?

A "Drain" is a fuel-level drop that can't be explained by normal engine consumption. FuelAnalyzer considers the drop speed, current ignition state, volume and time of day. The minDrainVolume parameter is tuned individually — 5 L for a passenger car, 50 L for a fuel tanker.

Which trackers are supported?

Teltonika (FMB920, FMB130, FMC130, FMC650, FMC880), Bitrek (BI 530R, 810, 910), and all devices with Wialon Retranslator and Teltonika Codec 8/8E protocols. Already running on another platform? We migrate without hardware replacement.

Do we need to register with PUESC if we drive to Poland?

Yes — for the transport of sensitive goods (fuel, alcohol, tobacco, fertilisers, etc.), Poland requires automatic position transmission to SENT via PUESC. cloudGPS is a registered OUL provider on the platform side: you enable data transmission in your dashboard with a single toggle for the specific vehicle. Registration at puesc.gov.pl is done by you as the carrier — we provide step-by-step guides and technical support.

How much does deployment cost?

cloudGPS is a server platform with a monthly subscription depending on the number of devices and chosen features. DUT installation and calibration are separate, performed by an installer (yours or from our partner network), approximately ~€80-150 per unit depending on complexity. Contact us — we'll suggest a partner installer and prepare an exact subscription quote.

How quickly will I see the first results?

DUT data appears in the dashboard as soon as the tracker starts sending telemetry. Accurate drain detection — after 1-2 weeks of operation, once the platform learns baseline consumption patterns and FuelAnalyzer parameters are tuned to your equipment. Our support team helps you tune the parameters in the web UI.
