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
