There are two primary uses for data gathered from meters: analysis and billing. Data from our systems can be used for both. The exchange of data between our system and a billing or analysis system is usually made through file transfers at scheduled intervals. Our data collection service is mainly used by invoicing systems. The business imperative for timely and accurate billing dictates the need for rapid data acquisition, without compromising its quality. Data collection is followed by validation and then the transfer of the validated data to another system for billing. The time taken to collect and transfer information determines the overall performance of the billing system. Other information, such as customer details and prices, is already available within the billing system, so the critical factor is the time taken to transfer metering data. We offer several different methods for transferring data, all characterised by a high degree of reliability.
