DIALOG® OSR   On site reading of water meters
Description: DIALOG® OSR (On Site Reading) is the simplest implementation of the DIALOG® system. A DIALOG® unit is attached to each meter, and they are 'daisy-chained' by a pair of wires out to a ReadPad®. A hand-held terminal is then used to read up to 63 DIALOG® units throught the ReadPad®. As an alternative, a Personal Computer can also read the DIALOG® units and automatically generate a bill on site.

Case Study: 57 DlALOG® Units were installed in the OSR format in a building complex in central Melbourne in November 1995. This site consists of three towers, for which three seperate DIALOG® networks were arranged. Meters at thgis site are in very hard-to-read locations - some sealed in walls behind closets and behind kitchen sinks. All these meters can now be read regulary and customers billed by the Utility.
Ordering: The easiest way to order and use DIALOG® is to have the meter supplied with the DIALOG® unit mounted to the meter, programmed and connected to a ReadPad as shown below. To utilise the more comprehensive networking abilities of the DIALOG® unit, contact your local RMC™ representative for ordering details. It may be necessary to provide details of the number of meters, number of floors, apartment numbers and floor plans.
