Large-bore Bluetooth NB water meter DN100

Type: Bluetooth water meter

Q_3：100

Accuracy Class: 2

Working pressure: 1.6 MPa

Temperature class: T30/T50

Temperature range: (-40~90) °C

Product Overview

The Bluetooth water meter adopts a low-power Bluetooth 5.0 chip and supports one meter for multiple Bluetooth APP accounts, ensuring user data security and ease of use.

Powered by batteries, this water meter has strict requirements for power consumption. Since the transmitted data volume is generally less than 128 bytes, it uses Bluetooth Low Energy (BLE) technology, with a transmission distance of up to 20 meters.

Bluetooth Low Energy (BLE) is a cost-effective, short-range, interoperable and robust wireless technology that operates in the unlicensed 2.4GHz ISM radio frequency band. Designed as an ultra-low-power (ULP) wireless technology from the very beginning, it employs a variety of intelligent means to minimize power consumption.

Key Advantages

Main Features of the Product

Prepaid Function: Users purchase water before consumption. The valve will automatically close to cut off water supply when the balance is insufficient.
Flexible Pricing Support: It supports single price setting, minimum consumption setting and tiered pricing setting.
Mobile APP Recharge: It changes the traditional water purchase mode, allowing users to recharge water conveniently at home via mobile phone.
Data Synchronization Display: The data on the mobile APP is synchronized with the mechanical part of the water meter.
Alert and Alarm Function: When issues such as low battery voltage, insufficient water consumption, strong magnetic interference or other faults occur, the valve will shut down. Users can log in to the mobile APP to check the cause of the valve closure.
Real-time Data Upload: Relevant information will be uploaded to the management system when users purchase water, enabling the management party to keep track of users’ water purchase status.
Automatic Valve Maintenance: The valve operates once every five days to remove limescale in a timely manner and ensure its flexibility.
Anti-hoarding Function: The system software can flexibly set upper and lower limits for water purchase to prevent users from hoarding water.
Easy Battery Replacement: A specially designed battery cover is located on the bottom side of the water meter base, making battery replacement convenient. Batch battery replacement is no longer a difficult task for water management departments.
