1. A sensor system for fluids, comprising:
two level sensors which are arranged vertically one upon the other on and connected to an electronic circuit board;
four electrodes of four conductivity sensors which are arranged horizontally next to each other at the bottom of and connected to the electronic circuit board, wherein the four conductivity sensors are arranged below the lower level sensor;
a temperature sensor which is connected to the electronic circuit board; and
a connector for connecting the electronic circuit board to a controller;
wherein the electronic circuit board is embedded in a hot melt compound which is surrounded by an injection molded housing.
