The unit has a battery-operated transmitter to transmit an acoustic signal. The transmitter has a sensor (1), that can move up to a stop (5). A slip contact (2) of the sensor connects to an inner lying battery (6), through current lines designed as a sensor control, and are connected to two electrodes (4) applied in the sensor. The filling level signal unit consists of a transmitter and a receiver and produces a radio signal transmission. |
