control of temperature inside device case (reference Information);
registration of random reverse flow of water (displaying the counted water modulo consumption
in forward and the reverse direction via the LED indicator);
leak fixation (continuous consumption < 0.3 cubic meter per 30 minutes);
fixation of a breakthrough (continuous consumption > 0.3 cubic meter per 30 minutes);
binding an emergency situation to the date and time and its saving;
testing in the manufacture and changing the parameters of the meter during operation through
the optical port;
reading and changing the parameters of the meter during operation through a local wireless
connection via the FSK radio channel;
pre-configured schedule for transmitting the collected data in the LoRaWAN
®
network via radio
communication (choice the communication period);
pre-configured schedule for the data collection and saving in the internal memory (choice the data
collection period);
emergency transmitting of the collected data (extraordinary session);
emergency transmitting of the alarm message in case of one of the next emergency situations:
o
fixation of external magnetic field influence;
o
low internal battery charge;
o
leak fixation (continuous consumption < 0.3 cubic meter per hour);
o
