As a fleet owner you may be looking for a gps tracking system with fuel level monitoring option. You will need a special fuel level sensor installed in the tank. There are many manufactures presented at market. How to choose?
Most of sensors have similar precision (unlike cheapest China products). What makes the difference?
1. Stability in all operation conditions.
2. Protection of electronic module from electric disturbances at vehicle onboard circuit.
3. Sensor protection from vandalism.
4. Reliable sealing.
5. Easy diagnostic and repair
6. Warranty terms.

We suppose you buy GPS tracking system not for 1 year of operation. Rather 7 years and more. At long term the cost of system maintenance becomes more important than price of aquisition. We have made all possible things to minizime this total cost (aquisition + maintenance) during lifecycle.

How we did it?

1. It is very hard to burn Eurosens Dominator. It can be connected to 170V power source for a long time. Onboard disturbances is not a danger anymore.
2. Thanks to the modular design it is very easy to make diagnostics and replace sensor if needed. It is not necessary to call a GPS tracking supplier to replace sensor (expensive voyage, sometimes more than sensor cost). You can replace burned sensor by yourself. After sensor replace a new tank calibration is not required (several hours of the vehicle downtime).
3. Sometimes you will need to switch GPS tracking system to another vehicle. And fuel tank may have bigger height. With Eurosens Dominator you can buy only new electrodes (very cheap) and don’t need to buy a new sensor.
4. It is very easy to disassemble and clean Dominator electrodes. You don’t need to arrange this service (after several years this procedure may be needed).
5. Eurosens Dominator don’t have a cable outlets (weak place of sensors).

So, you can save 30 USD and buy cheapest sensor. But difference with Eurosens Dominator not too big, it is more profitable to save much more money during lifecycle of GPS tracking system.
