Household water meters SHVE and SGVE

СХВЭ и СГВЭ Performance:

Electronic water meters SHV and SGV are intended for measuring the volume of cold and hot potable water. The meters are ideal for installation in apartments and cottages, as well as for wireless data transmission in combination with the AMR system built on the LPWAN technology based on the LoRaWAN protocol. Built-in radio channel allows transmitting meter readings, as well as emergency messages about emergency situations. <br><br> 42 months or 40 000 packets sent over the radio — warranty period 6 years — calibration period

Radio channel operation

The basis of the LPWAN technology data transfer principle (based on the LORAVAN protocol) at the physical level is the property of radio systems — an increase in the communication range with a decrease in the transmission speed.

The LoRaWAN network uses a star topology, where each device communicates with the base station directly. City or regional networks are built using the «star of stars» configuration.

A device with a LoRaWAN module transmits data over the air to a base station. The station receives signals from all devices within its range, digitizes and transmits to a remote server using an available communication channel (for example, Ethernet).

The data obtained on the server is used to display, analyze, build reports and make decisions. Device management takes place using a reverse link.

For data transmission over the radio channel, an unlicensed frequency spectrum is used that is allowed for free use in the network region (for example, 864-865 MHz).
