WEF-HV Smart Meter - 1

G2 misuratori THE VALUE OF METERING SMART METERS WEF-HV Smart Meter Direct reading smart meter with data transmission via radio frequency 868 Mhz, with the protocols listed below. -Counter with radio module Mod. WEF-R-CLW LoRaWAN protocol for fixed network and LoRa for Walk-by/Drive-by -Counter with radio module Mod. WEF-R-WMB W-Mbus OMS protocol for Walk-by/Drive-by -Counter with radio module Mod. WEF-R-W+L LoRaWAN protocol for fixed network and LoRa for Walk-by/Drive-by + W-Mbus OMS protocol for Walk-by/Drive-by W-Mbus OMS protocol for Walk-by/Drive-by: the system automatically switches between fixed network and Walk-by/Drive-by protocols. Whirlpool meter, gauges DN 50 to DN 200, temperature class T50, measuring range R80H Internal measuring mechanism can be inspected without removing the meter from the system - with DRY dial for turbid and strongly calcareous water. Inductive transmission between mechanical and electronic parts. Radio module can be replaced All models are MID-approved according to the applicable directive (module B+D), in accordance with EN 14154, OIML R49 and ISO 4064 Requirements for straight pipe sections: U0/D0 Installation permitted in any position (for non-horizontal installations, flow must be upwards. Transmitted consumption data, net compensated by possible reverse flows Multi-level cryptographic data security Transmitted data: sensor ID, consumption data, hardware status, alarms, battery level, leaks Data security via multi-level encryption Modification of configuration data possible from fixed network remotely and/or via radio terminal Resin-coa
