Ntse STS Dej Meters DN15mm DN20mm Token Dej Meters

Lub 'meter' txhawb nqa STS prepaid raws tu qauv. Tokens tuaj yeem raug xa mus rau STS meter los ntawm CIU, infrared unit, lossis meter keyboard kom paub txog kev them nyiaj ua ntej, hloov valve, thiab lwm yam haujlwm. Nyob rau tib lub sijhawm, lub concentrator txhawb LORA wireless tsis siv neeg kev sib txuas lus ntawm cov meters thaum nyeem ntawv. Networking muaj nuj nqi, theem network tuaj yeem nce mus txog qib 3, uas ua rau muaj txiaj ntsig zoo heev.

Lub ntsuas dej muaj cov yam ntxwv ntawm kev them nqi raug, kev siv yooj yim, thiab kev tswj xyuas kom zoo.

• Ua haujlwm zaus: 868MHz zaus band, tuaj yeem ntab nce thiab nqis ± 10MHz.
• Modulation method: LoRa linear zaus modulation.
• Kev siv hluav taws xob: static nruab nrab tam sim no<30uA, maximum power consumption during meter reading <2mA (use ER26500 lithium sub-ion battery to read the meter once a day and have a service life of not less than 6 years).
• Lub zog hluav taws xob: 3.0V ~ 3.6V
• LoRa kev sib txuas lus nrug: tsis pub tsawg tshaj 1000 meters kis tau tus mob nyob deb (nyob rau hauv qhib qhov chaw), thiab kev sib txuas lus nyob rau hauv cov cheeb tsam tsis tsawg tshaj li 300 meters.
• Kev khiav hauj lwm kub ntawm hluav taws xob qhov chaw: -40 ° ~ 85 ° C.
• Ua hauj lwm av noo ntawm hluav taws xob qhov chaw: 10% ~ 90%.
• Valve hloov lub sijhawm tos: 20 vib nas this.
• Valve thaiv tam sim no: Ntau dua lossis sib npaug rau 260mA.
• The maximum instantaneous drive current of the valve: >800 mA.
• Pulse sampling lub sij hawm: 0.25 vib nas this.

• Tsis yog -magnetic/magnetoresistive metering, siv cov lus txib los hloov.
• Tus naj npawb ntawm cov kauj ruam uas tuaj yeem teeb tsa tsis pub tsawg tshaj 10.
• Los ntawm cov cuab yeej kev sib txuas lus, lub 'meter' tuaj yeem pib ua ntej (rov pib dua lub ntsuas dej), thiab tus lej ntsuas dej, ntsuas lub hauv paus, ua haujlwm zaus, network ID, rov ntim dej ntim, ntim dej ntim, tshaj tawm ntim, ceeb toom, ntim ntim, hnub so dej noj, Flow cov ntaub ntawv, valve tswj, mem tes sib npaug, hnub rollover, tsim thiab sau ua haujlwm rau nyeem TID.
• Cov ntaub ntawv siv dej txhua hli (hnub tim, kev siv ntau ntxiv, cov ntaub ntawv ceeb toom) tuaj yeem khaws cia rau 10 xyoo.
• Lub suab tswb muaj nuj nqi: Lub ntsuas ntsuas emits lub tswb nrov thaum lub tswb tau tshwm sim.
• Lub moos muaj qhov chaw nres nkoj hloov kho tshiab rau kev hloov kho firmware.
