Fuel monitoring + GPS tracking in one device
How a major Qatari contractor brought fuel storages and tanker trucks under accurate, temperature-compensated control across 280+ machines.
A major Qatari contractor
Established in Qatar in 2007 as part of an international group operating in the USA, Africa and the Middle East, the company has delivered dozens of major projects — highways, airfields and city roads — and built its own asphalt, concrete and crushing plants.
- 1,700+ employees
- 5 building-materials factories
- 280+ machinery units
- 10+ years of operation
Work often takes place in remote locations with no fuel stations, served by stationary tanks (up to 50,000 L) and 3,000 L tanker trucks.
Manual measurement in 40 °C heat
Standard on-board equipment couldn't solve the problems of operating fuel storages and tankers. In the Middle East climate, daytime temperatures swing up to 40 °C, expanding the fuel significantly. Levels were read with a float sensor or dip-stick and corrected by tables — leaving plenty of room for error and undetected drains.
DUT-E GSM with temperature compensation
DUT-E GSM is a two-in-one device — fuel level sensor plus GPS/GSM telematics in one body. It installs faster than a “sensor + tracker” combination, measures volume to within 1%, and automatically corrects for ambient temperature. For stationary storages it ships as a 1 m probe with add-on sections, assembled to length on site. Real-time onboard reports to ORF4 include:
- fuel level (mm) and volume (litres)
- “refuelling”, “giving out fuel” and “fuel drain” events, with time and place
- route, location and speed of every tanker
With DUT-E GSM on six tanks and cisterns, dispatch could see real fuel volume at any moment — optimising tanker routes and delivery schedules and minimising unauthorised drains. Eliminating manual measurement also removed calculation errors and saved many working hours, cutting costs associated with fuel distribution and consumption by 45%.
Task → Solution → Result
Inaccurate fuel tracking in extreme heat
Manual measurements in 40°C+ temperatures led to errors. No way to verify fuel deliveries or detect unauthorized drains from remote storages.
DUT-E GSM two-in-one sensors
Fuel level + GPS tracking in one device, installed on stationary tanks and fuel tankers. Automatic temperature compensation, real-time alerts.
45% cost reduction
Optimized fuel delivery routes, eliminated manual measurement errors, and minimized unauthorized drains across all sites.
