Contactless reader NozzleCrocodile

NozzleCrocodile is used in the transport telematics systems to control petrol and gas fuel consumption of the vehicle.

NozzleCrocodile reads the control impulses of the engine injector and converts them into normalized impulses that number is proportional to the volume of consumed fuel.

The sphere of application is small commercial vehicles: cars, pickups, minivans, lorries and dual-purpose vehicles, in other words such machinery where it`s impossible to use fuel flow meter DFM because of underhood constraint space.

Signals reading is occurred without electrical connection to the nozzle control wires. So, there is no interruption into the vehicle electronic systems integrity.
