SmartSensor II – is a new generation fuel gauge unit (produced by our company), unlike the old one SmartSensor, the new unit was produced in ultrastrong, single-piece aluminum body. In the course of its production there were used new, more precise components, the unit can check the presence of water in a tank.
The fuel gauge unit SmartSensor II (hereinafter referred to as the Unit) is a noncontacting gauge of the level of combustive and lubricating materials (hereinafter referred to as the CLM): diesel, petrol, oil.
Operating principle – capacitive. A measuring probe tube and its inside bar make condenser plates, the capacity of which is changed if the CLM level is changed. In contact with electrically conducting fluid (for example water) inside the plates, the sensor value will correspond to full tank – the unit is not meant for measuring the level of electrically conducting fluids.Change of condenser capacities is converted by the electronic circuit into a digital signal which can be read, processed and transmitted to the server of GPS system of monitoring, traffic control and remote control of mobile objects «Inspector» by means of GPS monitoring device SmartTrack.
More detailed information on fuel flow monitoring for the otor-vehicle transport can be found in the description of a tariff «Fuel+» of GPS monitoring system «Inspector».
