Today, cassette toilets are the absolute standard in motorhomes. They are compact in design and have a display that unfortunately only indicates the full status. Once this is reached, the toilet in the vehicle can no longer be used. It is not possible to plan disposal in advance, which means that the toilet can only be used to a limited extent.

The tank electrode 20 K-WC has been further developed on the basis of the tried-and-tested tank electrode to create a fully-fledged fill level indicator especially for use in cassette toilets. The compact design makes it possible to simply screw the tank sensor into the toilet cassette from above using the mounting ring supplied. The 38 mm diameter mounting hole required for this is easy to make using a hole saw. The fully encapsulated electronics are designed to be waterproof (IP67) and suitable for harsh operating conditions when flushing the toilet cassette.

To change the cassette, the tank electrode 20 K-WC is disconnected from the vehicle via a solid 3-pin round plug and the plug is fixed to the cassette. In addition to the 3-pin round plug connection, the scope of delivery also includes a mounting ring and the complete mounting material.
