Continuous filling of liquid provides higher accuracy of fuel tank calibration;Description
DUT-E ATS-1 Tank Calibration Station is made for automatic calibration of fuel tanks of vehicles as well as stationary fuel tanks/cisterns up to 3,000 liters, where fuel level sensor is installed. The station is controlled via Bluetooth from Android-based smartphone or tablet. Automatic calibration station speeds up fuel tank calibration process by 2-3 times and provides higher accuracy of fuel tank calibration.
Operating principle:
1. After connecting the fuel level sensor to calibration station, an approximate value of tank volume is set in Service S6 DUT-E mobile app. That is necessary for further recording of 60 calibration points and generation of calibration table with equal step of filled fuel volume.
2. By pushing “START” button automatic uninterrupted fuel tank calibration begins: the station automatically pumps fuel from external tank into the calibrated fuel tank. Optimal speed of fuelling (3-5 times more calm than fuel dispenser for trucks at gas station) allows to avoid noticeable fuel fluctuations and foaming in the tank.
3. Generation of calibration table is made continuously as fuel tank is filling: values of fuel level in tank (measured by DUT-E CAN/DUT-E 2Bio/DUT-E GSM fuel level sensor) and corresponding values of filled fuel volumes (measured by inbuilt DFM Marine flow meter) are transmitted through Bluetooth to the Android device.
4. Mobile app automatically generates calibration table so the process of tank calibration with ATS-1 doesn’t require any attention of a technician.
5. After fuel fulling to calibrated tank is finished, tank calibration process automatically ends. The technician can save calibration table into sensor’s memory or save into a file for further transferring to GPS-tracker or online telematics/vehicle tracking server.
