Abstract
A measuring arrangement includes a first magnetic switch having a first contact and a second contact, and a second magnetic switch having a first contact and a second contact. A first evaluation terminal is connected to the first contact of each of the first magnetic switch and the second magnetic switch. A first resistor is arranged between the second contact of the first magnetic switch and the second contact of the second magnetic switch. A second evaluation terminal is connected to the second contact of the first magnetic switch. A third evaluation terminal connected to the second contact of the second magnetic switch.

A method for measuring a fluid level, comprising:
- providing a measuring arrangement including a first magnetic switch having a first contact and a second contact, a second magnetic switch having a first contact and a second contact, a first evaluation terminal connected to the first contact of each of the first magnetic switch and the second magnetic switch, a first resistor arranged between the second contact of the first magnetic switch and the second contact of the second magnetic switch, a second evaluation terminal connected to the second contact of the first magnetic switch, and a third evaluation terminal connected to the second contact of the second magnetic switch;
- measuring a first resistance value between the first evaluation terminal and the second evaluation terminal;
- measuring a second resistance value between the first evaluation terminal and the third evaluation terminal;
- and
- determining the fluid level based on the first resistance value and the second resistance value, both the first resistance value and the second resistance value vary as the fluid level varies.
