Products Description
This 15mm GPRS smart digital water meter is a specialized modern water management remote meter-reading product. It adopts mature GPRS cellular network communication technology with no need for wiring and transmits water consumption data to the backend water management platform in real time, avoiding traditional manual meter reading on-site.
There are three parts in the system: a GPRS water meter terminal, a SIM card (2G), and a cloud-based operation & management platform. The meter has a built-in GPRS communication module and uses the public cellular network to upload data to the platform. The cumulative flow, battery voltage, and the reported status of each water point can also be tracked and managed by the administrator at any time and from anywhere via the internet.
Core advantages
Utilizes mature GPRS/CDMA/3G/4G public networks to achieve reliable wireless data transmission and to reduce labor and transportation costs. Keeps billing disputes out of your pocketbook due to wrong reading by a human or extended reading cycles.
It is the same installation method as regular mechanical water meters. No need for extra wiring or for dedicated communication lines. Easy to install in new and old building projects. Designed for use in dispersed installations, rural dwellings, factory workshops, and irrigation systems.
Utilizes low-power laminate design with intelligent sleep strategy – the sensor is in deep sleep mode during idle time and only wakes up at the preset reporting times for 30 seconds to send data, then goes back to sleep. With a reporting rate once a day, battery life can exceed 6 years.
Water data sampling and uploading are supported 24/7. Managers view live flow and cumulative consumption and receive abnormality alerts. If a continuous low flow (leakage suspected) or high flow at an unusual time is detected, the system will send instant alert messages, allowing early detection and remedy for pipeline leakages.
How it works
GPRS Water Meter Working Principle
This 15mm GPRS smart digital water meter enables remote reading and real-time monitoring via cellular network.
GPRS System
Each GPRS water meter is equipped with a SIM card and transmits data directly to the cloud platform via a 2G/3G/4G cellular network. The meter wakes up at scheduled times, goes online for 30 seconds to upload data and receive commands, then returns to deep sleep to preserve battery life. The system administrator can send valve control or meter reading commands from the platform to the meter at any time.

Applications
Where to Use This Meter
This 15mm GPRS smart digital water meter is ideal for remote reading in residential, commercial, industrial, and agricultural applications where scattered installation and real-time monitoring are required.
Residential Communities
Remote centralized reading replaces manual door-to-door reading, reducing property labor costs.
Commercial Complexes
Sub-metering and energy consumption monitoring support detailed cost allocation.
Industrial Parks
Monitoring production water usage detects leaks quickly and aids water conservation.
Agricultural Irrigation
Remote monitoring of irrigation usage solves meter-reading difficulties in remote areas with no wiring required.
System Solutions
System Solutions
Prepaid Water Meter System
End users pay water bills with IC cards. The water meter closes the valve and stops the water supply when the balance is zero. The prepaid eliminates bad debt and reduces billing administration.
AMI System
All users' water consumption is monitored via a cloud platform. Data can be sent to the water supply company's service platform through data docking. Abnormal usage meters trigger automatic alerts, enabling rapid response.
Pipeline Leakage Detection System
Utilizes high-accuracy ultrasonic water meters (accuracy up to R400) in the main supply pipe – even small flows from a single home can be measured. The system computes the leakage degree and leaks in the pipeline by subtracting sub-pipeline usage from main pipeline usage.
Software Platform Advantages
Software Platform Advantages
Our GPRS smart water meter system uses public cellular networks for direct data transmission, offering simple installation, stable signal, low power consumption, and active remote control.
GPRS System Advantages
- Simple Installation – Same method as mechanical meters, no extra wiring.
- Stable Signal – Reliable transmission, not affected by distance.
- Low-Power Design – Online 30s per cycle extends battery life.
- Active Control – Remote valve and meter reading commands.
LoRa System Advantages
- Low Power Consumption – Short-distance communication extends battery life.
- Real-Time Control – Send meter readings or valve commands via concentrator.
- Low Operating Cost – Only the concentrator needs a SIM card; meters do not.
FAQ
Common Problem
What is the battery life of this GPRS water meter?
At a daily reporting frequency, the battery lasts over 6 years. Battery life varies depending on reporting frequency – longer intervals extend battery life.
Is this meter suitable for cold water only, or can it be used for hot water?
This model is designed for cold water (0℃ – 30℃). For hot water applications, please contact us for a suitable variant.
Can I use NB-IoT or LoRa instead of GPRS?
Yes. This meter platform supports optional NB-IoT and LoRa communication modules. Please specify your network preference when ordering.
How is data secured during transmission?
Data is transmitted via encrypted GPRS/NB-IoT networks. The cloud platform supports access control and data backup to ensure security.
