Regions and markets differ greatly with respect to meter reading and the placement of water meters. It is often a matter of tradition rather than deliberation.
The MULTICAL 21 therefore uses a standardized wireless communication, Wireless M-Bus, which is interoperable with other household meters and can be integrated into mesh networks. The data package transmitted as one-way communication every 16 seconds contains Current meter reading, Meter reading on the first day of this month, List of active info codes, and List of info codes which have been active within the latest 30 days.
Intelligent alert system
Info codes are an alert system on some of the most common problems in water distribution. The info code ‘Leak’ is a notification that the meter within a 24 h period has not registered at least one hour with zero consumption. The info code ‘Burst’ signals an excessive flow, which may be caused by a pipe burst. Other very important info codes are ‘Reverse’ indicating a backflow of water, which can give an early warning that the drinking water is being contaminated, and ‘Tamper’ indicating that the meter has been tampered with.
Info codes and alerts lever the water meter into a new role as a tool for analysis and trouble shooting. The utility will have a number of possibilities for settling customer disputes and for optimizing the supply network when for example leaks can be quickly detected and repaired.
Via an optical eye on the front it is even possible to access data loggers and read out historic data. The quick overview of historic consumption data enables a precise mapping of consumption patterns and facilitates a more customer oriented counseling on water consumption. The data logger shows monthly data 36 months and daily data 460 days back in time.
Award winning water meter
The MULTICAL 21 water meter has been created in cooperation with the Danish design consultancy design-people. The philosophy of the design is to present advanced and innovative functionality in a simple exterior that plays down the complexity and increases the user-friendliness. This philosophy resulted in the prestigious “iF Product Design Award 2012
” and in the “Smart Water Metering Innovation of the Year Award 2012
