Prepaid Smart Gas Meters
Prepaid CardLess BLE NBIoT
System Overview
- The AMR (Automatic Meter Read)System, provides the utility with the ability to read a meter without entering the home. Based on Narrow Band IoT technology, the Wave FN AMR solution gives the energy supplier fast, reliable meter readings.
- This data can be used by the energy supplier to provide accurate upto date billing, removing the need for estimated readings on the occasions when access to the meter is not available.
- The Wave FN AMR module can be retrofitted to various brands of diaphragm gas meter apart from Raychem RPG brand, allowing the meter owner the possibility to implement AMR at a point in time after the meter has been installed.
- By utilizing up to date existing Telecom Network the transmission distances are long. This usually determines that the meter reader can read whole apartment blocks without the need to enter the building. The data can be downloaded from the Wave FN AMR module into CLOUD/Central Server.
- Alerts & Alarms also be sent in the event of a Wave FN AMR module having a low battery, or if a tamper is thought to have taken place. Once that data is received to the Cloud Database or server based at Customer Server Room via NBIoT. Having reached the Cloud data base the utility now has the option to use the Wave operating software to produce information for generating bills, send customer SMS's, Customer e mails, and generally manage their customer data base.
- The meter pulse sensor fits directly onto the meter index. It collects the pulses generated by index, passes to external AMR, where AMR monitors the energy count stores and supplies information to the server and the server provides Alerts/Alarming to authorized person along Billing dates for verification.
- The AMR supports two types of Pulse sensing, based utility needs:
- Magnetic Pulse
- Inductive Pulse
The Advantages of Fixed Network for the Utility
- Meter reading without entering the property
- Reliable reads removing possible reading errors
- Secure reads preventing fraud
- Fast – a 96 apartment building in 5 minutes
- Reduced back office staff as there are no estimated reads
- A green solution
The Advantages of Fixed Network for the Customer
- Secure – no third party entering the house
- Reliable – no meter reader mistakes
- Paperless
- SMS/e mail updates
- A green solution
The NBIoT AMR Module
The wave meter module is fitted onto the meter. It counts the pulses generated by the index wheel and translates this into the index reading. At a pre-determined interval (usually daily 2 times) the NBIoT AMR module will attempt to transmit the current Index value to the remote meter reading devise. Along with the index reading, the meter serial number and any generated alarms will be transmitted. Environmental Condition: Temperature: 10-650C, RH:<95% IP65 & E-021(ETL)
The Wave NBIoT Module Specifications
- Based on the IEE Standard
- Operates in Unlicensed Bands
- Integrated low power modes upto 2uA

The Android Mobile App
A user friendly mobile app is used to as an admin Login for utility/service provider to monitor the meter functionality features, such as tamper’s battery voltage balance, service mode enable, commissioning etc., At present it supports Android OS above version 4.4. The mobile must be a healthy mode with GPRS network communication.

The Operating System - on Cloud / Server based at Customer end
- The Cloud computing service for The Operating System(OS), utilizes internet technology, allowing users to instantaneously access data via PC Terminal, smart phone, or tab.
- The OS application software is installed on the server.
- The utility supplier selects the parameters from the OS that he wishes to use, designing his application around his own requirements. The packages available cover the complete range of functionality from entering a new customer all the way through producing his bills online.
- Access to the database is controlled via a security user name and password. There are five levels of security available, each has different limits as to what data can be viewed or changed.
