The sensor is installed in the Ad-Blue tanks of an automotive SCR system. Generally used in passenger car application targeting emission reduction system

The sensor allows the continuous measurement of the AdBlue tank level, enabling the calculation of the residual Km available before refilling.


Eltek capacitive technology can guarantee compact dimension, no moving parts and reliable measure in any condition. Furthermore, Eltek sensor is the only one on the market able to guarantee reliable measurement also in water freezing condition and mixed state (water+ice). This allow for example ‘Refilling on Ice’ measurement and the capability to distinguish what part of the fluid in the tank is frozen (cannot be injected) and what is liquid (can be injected).
