Signaling system for number of dispensers, has sensors for determining degree of filling of dispensers and arrangement for transmitting data from sensors to display unit

摘要

The signaling system has sensors (5-8) for determining the degree of filling of dispensers (2-4) and an arrangement for transmitting data from the sensors to a display unit (15). Optical, or acoustic sensors or mechanical, e.g. weight, sensors can be used. Cables (9-12) or transmitters (19-21) and receivers (25) can be used for data transmission.
