1. the multimeter to test the Voltage analog line on the processing box to see whether there is the stable voltage output and the voltage range is from 0 1V to 6 0V and the higher fuel level that the bigger voltage is If there is no voltage value or the value is not normal then please back to the 2nd step to choose the new position 4 Clean the couplant on the sensor effective surface and tank metal contact surface and spread one layer of glue over the effective surface sensor also cannot contain bubbles After it press the sensor probe into the tank bottom not too strong which is tightly closed to the contact surface Use a multimeter to measure whether the voltage signal is normal or not if the signal is not normal separate the sensor with the tank sooner If the Signal is normal keep pressing for 6 10 minutes until the glue preliminary curing 5 After the Glue solidification re measured voltage from the analog line voltage should be between 0 1 6 0V 7 8 6 The processing box should be installed in one friendly position to the driver The power supply is connected with the vehicle battery seriport or analog line GND line is connected to the external device like GSM GPS device refer to the pics 4 7 After the installation please restart the whole set 3 5 Attention 1 Signal extension line should be wrapped in one layer of protective sleeve such as heat shrinkable tube casing The wiring should be along the vehicle frame2. accuracy The resolution of fuel level height is 0 1mm measurement accuracy is 0 5 The equipment works well even under high temperature and cold external environment condition Long term and stable performance This equipment adopt the technology of non contact ultrasonic detection different from the current used direct contact of float type pressure type magnetic sliding type so it can avoid corrosion and pollution by fuel and keep long term stability of performance 2 8 3 Easy installation and maintenance No need to drill on fuel tank just install the ultrasonic probe onto the bottom or tank will not damage original tank and its measuring system Ensure the normal operation of vehicle original fuel guage 4 Environmental protection without pollution little energy consumption non contact measurement avoid dirt and fuel contamination caused by punching hole on tank 5 Strong reliability still work normally under the harsh environment moistureproof acid proof flame retardant anti interference and intelligent This product can be used separately through data screen view directly also be used with GPS devices through the GPS device to transmit data to the server for data statistics analysis and query statements 2 4 Application Range The product is geared to all kinds of vehicles such as logistics cars taxis buses commuter trains etc to digital records vehicle refueling the fuel situation prevent the oil theft
3. or the original wiring position The extension line should have at least 20cm distance with the vehicle heating part The extension line should be bound every 50cm 2 If necessary it is allowed to lengthen the extension line but the total length of the extension line should be no more than 15 meters 3 Red line connect positive of car battery black line connect negative 4 Guarantee 1 one year warranty repair replacement and refund free repair during warranty period Lifelong maintenance 2 During the warranty period repair cause to freight cost paid by the sender 8 8
