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
