Wireless remote transmission water meter

Measurement principle：Wireless remote transmission water meterAdopting a dual reed switch detection method, when the pointer of the water meter rotates, it drives the magnetic steel to rotate, and the reed switch closes or opens under the action of the magnetic field, thereby converting the measurement information of the mechanical water meter into electrical signals, effectively avoiding errors caused by electromagnetic interference and pulse jitter.

Principles of CommunicationThe communication module is usually in a sleep state, waking up once every second for a short period of time to listen for wireless commands. If there is, activate the receiving function to receive data; If not, continue to enter sleep mode. This greatly reduces the average power consumption of the module and extends the lifespan of the battery.

Diverse communication methods：Wireless remote transmission water meterSupports various wireless communication technologies such as LORA and NB IoT, among which LORA transmission mode can greatly extend communication distance after installing relays; NB IoT has advantages such as wide coverage and stable connectivity.

low-power designThe overall circuit adopts ultra-low power consumption design and is powered by high-capacity lithium batteries. The battery life can reach more than 6 years, reducing the cost and workload of battery replacement.

Easy to installThe RF module and the base meter adopt an integrated structure with a built-in antenna, reducing the risk of antenna damage during installation. The installation of the water meter is similar to that of a regular water meter, without the need for pre embedded signal transmission pipelines, drilling and threading.

Good protective performanceAdopting a fully sealed design, all circuits are sealed with epoxy resin, with no exposed electrodes, and can work stably in humid and harsh environments. Some products have achieved IP68 protection level and passed salt spray testing and high and low temperature cycle testing.

Accurate and reliable dataThe verification method used, such as a 16 bit CRC code, outputs accurate meter readings with a verification code. If there is interference during transmission, the receiving end can detect it, and the system will send three consecutive times within the set time to ensure data accuracy.

Remote meter reading functionAfter setting up the meter reading task in the management center, the system can automatically read the water meter data information in the area, achieving unmanned fully automatic meter reading. It also supports manual meter reading function and can read water meter data at any time.

Remote control functionThe water meter is equipped with a valve inside, and the management center can remotely control the opening and closing of the valve at any time, which facilitates the management and control of water use, such as water shortage due to arrears, valve closure due to faults, etc.

Abnormal monitoring functionEquipped with battery voltage detection function, it can upload to the management platform in a timely manner when the battery is running low; It can also detect abnormal situations such as magnetic interference and idling. When two reed switches are simultaneously attracted by magnetic interference, the valve automatically closes and opens automatically after the interference disappears, ensuring the normal operation of the water meter.

Data Storage and QueryThe module has a power-off storage function, and the power-off data is not lost. It can operate normally after power is restored; The collector is also equipped with a calendar clock chip, which automatically stores the daily cumulative water consumption value and status of the previous 31 days in a cyclic manner, facilitating the analysis of water consumption17.

Intelligent analysis functionBuilt in abnormal water usage recognition algorithm, capable of detecting 6 types of abnormal water usage behaviors such as continuous small flow, sudden increase and decrease, with a warning accuracy rate of 92%; Through vibration sensors and machine learning technology, 12 common faults such as magnetic interference, idling, and low battery voltage can be automatically detected, with an accuracy rate of over 95% for fault warning.

residential communityImplementing remote meter reading for each household, improving meter reading efficiency and accuracy, facilitating property management departments to settle water bills and manage water usage, while also reducing interference with residents' daily lives.

industrial and commercial usersFor places with high water consumption such as factories, enterprises, and shopping malls, real-time monitoring of water usage can be conducted for cost accounting and analysis, which helps optimize water usage strategies and reduce water costs.

Municipal water supply managementAssist the water supply department in achieving comprehensive monitoring and management of the water supply network, timely discovering leakage points, reducing the leakage rate of the network, improving water resource utilization efficiency, and ensuring the safety and stability of urban water supply.
