MULTICAL 21 measures by means of ultrasound which is the most accurate measuring principle, and irregularities are shown in an easy and clear way through info codes in the display.
MULTICAL 21 constantly monitors the consumption and registers a flow already at few litres per hour and thus detects even small leaks. If the water meter in the course of one day does not register at least one hour without flow, it sends a notification about this in the form of an info code indicating a possible leak. This provides time to solve the problem, before it develops into a serious leakage.
Other info codes
Burst: The water consumption has been unusually high for 30 minutes.
Tamper: An attempted tamper has been detected.
Dry: There is no water in the meter.
Reverse: The water flows in the wrong direction through the meter, or the water meter is falsely installed.
