Pinpoint accuracy
Ultrasonic flow measurement guarantees pinpoint measuring accuracy. The electronic meter has no moving parts, meaning that there is no wear and that MULTICALR 21/flowIQR 2101 is resistant to any impurities in the water

Many possibilities for communication
The water meter comes with the newest radio technology to meet increasing market demands for smart metering, both for ’Drive-by’, network or Sigfox installations. Radio packages are available with transmission intervals of 16 or 96 seconds for Wireless M-Bus and daily for Sigfox. Consumption data can be read manually directly from the display or using an optical eye. Furthermore, consumption data can be remotely
read by means of Wireless M-Bus, which is built into the meter.

Temperature
The meter measures both water and ambient temperatures

Low leakage limits
MULTICALR 21/flowIQR 2101 has built-in sensitive leak monitoring, as low as 0.1 % of Q3, which means that even the smallest water losses are detected very quickly. The unique combination of pinpoint measuring accuracy, longevity and built-in radio communication reduces the operating costs for the water company continuously and contingencies, caused by any leakage, are minimized, as waste of water is discovered immediately.

Long range
MULTICALR 21/flowIQR 2101 is equipped with a long range antenna that transmits strong radio signals with intelligent coding to the network. The meter can also be read from a long distance with ’Drive-by’.

Installation
The water meter is easy to install in all operating environments, horizontally as well as vertically, independent of piping and installation conditions.

User-friendly
The meter comes with a large and easy to read display and the meter is constructed as a hermetically vacuum sealed unit, which prevents humidity from reaching the electronics.
Therefore condensation water between the glass and the large display is avoided.

Wired M-Bus
The meter is also available in a version with Wired M-Bus, providing a comprehensive datagram acc. to EN 13757:2013 – used in applications using M-Bus protocol. MULTICALR 21 with Wired M-Bus is ordered under the name flowIQR 2101.
