Lector sin contacto NozzleCrocodile


Contactless injector pulse reader

Nozzle BMCrocodile is used within vehicle telematics and GPS tracking systems for fuel consumption monitoring of personal cars and small commercial vehicles.

Nozzle BMCrocodile reads control pulses from wires of engine injector (nozzle) and converts them into normalized pulses, which are sent to data processing unit. Number of sent pulses is directly proportional to the volume of consumed fuel.

Advantages of Nozzle BMCrocodile

Contactless reader Nozzle BMCrocodile

Safe connection to nozzle control wires

NozzleCrocodile reads signals through wire insulation without damaging wires. Contactless readers has no influence on signals in control wires.

Operation without presetting

NozzleCrocodile is a ready-to-use pulse counter, which does not require pre-configuration – no service kits, no service software.

Universal pulse output

NozzleCrocodile can be connected to almost any telematics unit or display, equipped with pulse counter input.

This table contains information on integration tests of Nozzle BMCrocodile and various telematics units, carried out to confirm compatibility and accuracy of data. To get more detailed info on connection and set up – click on link or logo of corresponding telematics unit in the table.

Generally, Nozzle BMCrocodile reader can be connected to any pulse-counting input with corresponding technical specifications. Nozzle BMCrocodile’s output signal is the same as DFM fuel flow meter’s with pulse output. See Technoton Document Center for more information.
