Type number Only for selected markets.

Meter sizes The meter is available in cold and hot water versions, controlled by the type number, which is: 8XX for cold water and 7XX for hot water. XX = country code YY = choice of communication – also see section ‘Ordering Details’. Different extension pipes can be enclosed as accessories. These extension pipes make it possible to adjust the meter to most existing current overall lengths. (See Accessories for Water Meters: 58101270).

Display and info codes The water meter can be read from the large, easily readable, specially designed display. The five large figures indicate number of cubic meters. The three small figures are decimals. The sign L (to the right of m³) will always be off when the meter is in operation as it is solely used during factory control and verification of the meter. The flow arrows in the left side of the display indicate water flow through the meter. If there is no flow, all arrows will be off. The info codes in the display have the following meaning and function: Info code flashes in the...

Temperature monitoring MULTICAL® 21/flowIQ® 2101 measures water and ambient temperatures respectively. The measurements can be used to monitor the installation and to give an indication of the quality of the water. Both temperatures are logged in the daily, monthly and yearly records. Minimum, mean and maximum values are being registered daily. The register contains the last 460 days. The first day of each month minimum, maximum and mean temperatures are stored in the register. The first day of each year minimum and maximum temperatures are stored. The register contains the last 36 months,...

Data registers The water meter has a permanent memory, in which the values of various data loggers are saved. The meter includes the following registers: Data logging interval Yearly logger Monthly logger Daily logger Info logger Data logging depth 10 years 36 months 460 days 50 events Logged value See table below See table below See table below Info code, meter reading and date It is always possible to read target volume and info codes for each of the latest 36 months as well as corresponding meter reading and possible info codes for each of the latest 460 days. The loggers can only be...

Optional data packages Wireless M-Bus Part of the data transmitted through the Wireless M-Bus radio signal is optional. It is possible to choose between different protocols (C1, T1), and various reading intervals, by choosing a specific module. Each module contains the option of choosing between up to 10 different data packages. You MUST choose one data package. 868 MHz C1 40/XX* Modules with actual values Module – ‘Radio disabled’ *) For more module options see document 5512-2336. Note that the logger is reset whenever you change between the various modules. Also note that the target date...

Data package options Sigfox Part of the data transmitted through the Sigfox radio signal is optional. It is also possible to choose between the different data so it changes from one data package to another. The target volume is mandatory for each transmission, but transmission 1 can have information on max flow, whereas transmission 2 can have information on min. flow. This is called ‘Sigfox sequence’.
