Rotor type NB remote water meter
Features
This water meter is based on a rotary-wing dry multi-flow meter, and has a smart remote water meter with two display modes: mechanical and electronic. Built-in NB IoT chip, which uses many proprietary intellectual property rights such as “patent ball valve technology” and “anti-magnetic patent technology”, which has the advantages of convenient installation, accurate measurement and reliable performance. It is a water company. The ideal IoT water meter product for water management departments such as real estate property companies.
一、Technical characteristics：
The base table complies with the national standard GB/T778-2007 "Drinking cold water meter and hot water meter"
All technical indicators are in line with CJ/T 224-2006 "Electronic Remote Water Meter" standard
"Patent ball valve", "anti-magnetic patent" and other patented technologies, is the preferred charge management measuring instrument of the water company
Using a dry base meter, the NB-IOT wireless intelligent control module and chip are fixed on the internal circuit board of the water meter.
Table valve integrated design, the valve can be added in the table, support remote control valve, superior performance
Micro-power design, built-in high-capacity lithium battery, to ensure the normal use of water meters for more than 6 years
Anti-freezing function: The whole table uses patented technology to improve anti-icing performance within -8 °C
Timed reading function: regularly report water consumption data every day through the NB-IOT platform network
Battery voltage reading function: periodically report battery voltage data through the NB-IOT platform network
Support ladder water price, support prepaid, postpaid
