A meter for remote reading of a utility such as gas, water or electricity comprises a measurement sensor (30), a radio receiver (31) and a radio transmitter (32), for transmitting measurement information generated by the sensor. The radio receiver and transmitter cooperate to pass on information from other meters. Flow control means can be connected to the receiver to enable remote control. Communication between each meter and a hub (5) is carried out by hopping along chains of meters in neighbouring premises. <IMAGE> |
