Electronic Water Meters Technologies







IOT (Internet of Things) compliant compliant metering metering solutions. solutions. Prepaid metering solutions with with alternative charging methods to smart cards and GPRS communication (STS, Bluetooth, Wifi) Low Cost Fixed network network metering solutions alternative alternative to GPRS and Ethernet communication (Lora)





AMR water meter with built built in Lora Lora Module Module (Integrated and Compact solution, no need to additional retrofittable amr modules) Implementing UM1-Lora UM1-Lora Modules Modules for AMR-ready water water meters.







New mathematical models for ultrasonic time of flight measurement, reducing cost and power consumption. Ultrasonic - Digital processing of Transmitted & reflected reflected sound signals, increasing the resolution of the time measurement to 20 picoseconds. Eliminating the requirement for discrete Analog Front Front End and and additional high cost electronic components, resulting a lower cost c ost for  ultrasonic water meters.









Wireless MBUS (Using FSK, Traditional Traditional RF principle principle for short range communication) Lora (Long Range  Chirp Spread Spectrum fully customizable low power communication network and meters, with lowest almost-no communication costs. –

Sigfox (Long Range  Ultra Narrow Band low power communication network and meters, needs investment for sigfox infrastructure by local operators, communication costs will be defined by operators in a similar way like GSM and GPRS.) –

NbIOT (Similar solution solution like Sigfox, Sigfox, which which requires infrastructur infrastructure e and pricing by local network operators. Hardware similar like GPRS module)







Bluetooth (Short range open protocol  mainly used as HMI for data entering to and/or reading from water meter. meter. Secure only if it is supported by additional security algorithms such as STS ST S and AES) –

GPRS (internet connection to the meters from the server, server, directly or  over gateways. In case of direct connection, each meter must have a built-in Gprs module and a sim card.)

Wifi (In case of meters meters are installed installed within the coverage of a WiFi network : Access Points, ADSL modems etc) Communication costs may vary depending on internet service supplier.

LoRa Water Meter Technology

Basically the system has two types of reading method. Reading the meters via a handheld computer (PDA) with a staff staff,, or a computer computer based based system system in a vehicle. vehicle.







These mobile remote reading devices collect meter readings and save them to local memory. In the municipal water autho uthori ritty cent center er,, the the readings are transferred to main system from the handheld terminal. Right after the successful transm transmiss ission ion proces process, s, the billing procedure starts.





As a summary, the system consists of three main parts: Water meter, Mobile Reading Device and the System Software. The AMR Mobile System utilizes only RF (Radio Frequency) communication. (No (N o need need to a GSM GSM/GPR /GPRS S operator)



System includes AMR Meters, Collectors (RF and GPRS) and Manage Manageme ment nt Softwa Software re via Inter Internet net.. Fixed Fixed Network Network Syste System m remotely collects meter data by using RF (Radio Frequency) and sends sends them to Central Central Compute Computerr System System via GPRS. GPRS.

Fixed Network System remotely collects meter data by using RF (Radio Frequency) and send them to Central Computer System via GPRS. The module utilizes the license free ISM band of 868 MHZ frequency.





Each user has a separate separate login defined defined by his own own username username and password, specifically configuring the system according to dedicat dedicated ed authorizat authorization ion level level.. Users manage the whole system as well as meter states, statistics. Several rich content reports and analysis graphics are  provided by the system.

Customers can manage their own consumption records such as invoice, debts, payment etc. from internet with their passwords.





System is cost competitive when compared to other AMR technologies. Water meter states may be observed everywhere regardless of current location.
