Abstract

An autonomous pulse reading and recording system is aimed at expediting centralised reading of meters generating or sending out pulses, likewise expediting consumption billing. The system is specifically useful for water, gas or electricity meters, but can likewise be used for telephone or telex meters or those used in any other system generating or sending out pulses. The system carries out a wholly automatic serial reading of a number of meters, avoiding possible human errors. Serial reading of the various meters can be effected from a distance, by radio or merely using a portable readout processor or normal computer. Another object of the system is to allow simple and inexpensive increase of the number of meters to be read out.
