Automatic tank calibration station

DUT-E ATS automatic calibration station is used by telematics technicians for calibrating fuel tanks of vehicles and stationary machinery, where fuel monitoring is done by additional accurate fuel level sensors.

DUT-E ATS accelerates the process of installing a fuel monitoring system and allows creating a highly accurate calibration table (surpassing manual tank calibration), while reducing the risk of mistakes.

Automatic mode of DUT-E ATS brings the most results — once the station is launched, a technician can tackle other tasks and get back when calibration is finished. Automatic mode is available for DUT-E fuel sensors.

Advantages of using DUT-E ATS

  • 2-3 times quicker installation of fuel monitoring system;
  • accurate tank calibration: 57 points, inaccuracy ±0.5% of tank volume;
  • exclusion of the “human factor” and possible mistakes;
  • calibration of complex tanks equipped with up to 5 sensors;
  • auto shut-off when pressure or temperature is exceeded;
  • quick-detachable connections for fuel hoses;
  • control using a smartphone via Bluetooth;
  • self-diagnostics of station operation during calibration.

DUT-E ATS application

DUT-E ATS calibration station works with all models of DUT-E fuel level sensors in the following modes:

  • continuous (except for DUT-E A5 and DUT-E A10) — the station continuously pumps fuel, adds points to the calibration table at regular intervals (portions). Suitable for standard fuel tanks.
  • automatic — the station pumps fuel in portions, waits until the fuel level stabilizes and adds the point to the table, then pumps the next portion of fuel. Suitable for tanks of complex shape with bulkheads.

With third-party level sensors, DUT-E ATS operates in a semi-automatic mode — it pumps fuel in portions, the current volume in the tank is displayed in a mobile app, and fuel level readings are entered manually into the calibration table.

How DUT-E ATS calibration station works

Automatic fuel tank calibration

  1. After starting, the station automatically pumps fuel from the auxiliary tank to the calibrated tank through a built-in DFM Marine fuel flow meter.
  2. The total tank volume (entered to the app) is divided into 57 calibration points by Service ATS mobile app.
  3. Fuel volume (DFM Marine readings) and corresponding fuel level in the tank (sensor readings) are transmitted via Bluetooth to the mobile app.
  4. The station generates a calibration table, according to which it builds a graph of the dependence of the fuel volume on the fuel level in the tank.
  5. After filling the calibrated tank, the procedure is automatically finished. The generated calibration table is saved to the sensor memory and to a file.
