1. What is an intelligent wireless remote water meter?
Intelligent remote water meter is composed of a regular mechanical water meter and an electronic acquisition and communication module. The electronic module completes signal acquisition, data processing, storage, and uploads the data to a relay or handheld meter reader through a communication line. The meter body adopts an integrated design, which can record and save the user's water consumption in real time, or directly read the current cumulative number. Each water meter has a corresponding code, and when the smart water meter receives the meter reading instruction, it can immediately upload the water meter data to the management system. This is called smart remote transmission water meter.

3. Reference price for intelligent remote water meter
Intelligent remote water meters are divided into two types: wired and wireless:
A. The functional characteristics of wired intelligent remote water meter:
1) Implementing prepaid and remote meter reading functions has solved the problem of IC meter charging but not being able to understand its usage.
2) It is possible to use wireless control to forcibly shut off the valve of the user's water meter, achieving a forced water outage for malicious arrears users.
3) Implement wireless remote meter reading and monitoring to understand the usage of IC card users, including the working status of the meter, the amount already used, and the remaining amount of water.
4) Realize wireless remote control, including wireless remote meter reading, setting meter parameters, and opening and closing water meter valves for easy maintenance and testing.
5) Connect with two types of sensors, reed switch sensor and Hall sensor, to achieve accurate electromechanical conversion measurement.
6) Check the battery voltage. When the battery voltage is lower than the set voltage, the gas meter will close the valve and give an alarm, prompting to replace the battery.
7) Easy to install, the installation is the same as that of a regular mechanical watch, and the system automatically connects after installation. Due to the use of wireless communication, there is no need for wiring between the meters inside the building, and data is directly transmitted through wireless communication. Suitable for renovation projects of old buildings.
8) Due to the wireless working mode, each single meter is self-contained, and there is no need to check the connection lines during maintenance and repair. The fault meter can be directly checked, solving the problem of checking the bus and determining the fault meter for wired transmission.
9) The module has an automatic activation mode for the battery, which can ensure the service life of the batteries in the meter. Avoiding battery damage caused by passivation.
10) The transmission of data adopts strict encoding and verification measures to ensure the accuracy of data transmission.
B. Wireless intelligent remote transmission water meter features:
1) Classification of wireless IC card intelligent remote water meters:
2) According to different electromechanical conversion methods, it can be divided into real-time conversion remote water meters, direct reading remote water meters, pulse wireless remote water meters, and passive thick film direct reading remote water meters.
3) According to the different wing wheel structures, it can be divided into: spiral wing remote water meter and rotor type remote water meter
4) According to the immersion method of the counting device, it can be divided into dry remote water meter and wet remote water meter
The reference price for intelligent remote transmission water meters varies depending on your usage environment, function, and diameter. The price for household intelligent remote transmission water meters generally ranges from 200 to 600 yuan. We hope you can call us for detailed consultation.
