Gas meter solutions:

(1) Elster gas strap loraWAN meter reading solution

Solution introduction: Our company provides a matching electronic backpack structure and loraWAN communication solution based on the elster gas meter provided by European customers.

(2) NBw wireless remote transmission dual-mode gas meter solution

Solution introduction: The installation environment of the water meter is harsh and the obstruction is serious. Neither the NB-IoT base station nor the water meter can move, resulting in a communication blind spot for NB-IoT meter reading. However, adding more base stations for a small number of nodes is costly, and sometimes the application scenario is still incomplete. solve. Hua Aotong provides a dual-mode solution for NB-IoT by using the HAC patented low-power wake-up patent and self-developed wireless chip, making up for the shortcomings of NB-IoT in practical applications.

(3) WE wireless remote transmission smart gas meter solution

Solution introduction: HAC-WE low-power wireless meter reading system adopts LPWAN + LPLAN network topology. The system includes acquisition and measurement, two-way communication, meter reading control valve and meter reading application platform. System features: high-frequency sampling of two-way real-time big data to enhance data value; simple system architecture, self-encrypted coding, safe and reliable, and low-cost system , low power consumption; easy to expand, easy to install, flexible deployment, especially suitable for meter reading application scenarios where meter reading requirements cover a wide area and households are sparsely distributed.

(4) DIEHL non-magnetic water meter strap loraWAN meter reading solution

Solution introduction: Our company has designed and completed the electronic back including communication solutions based on the DIEHL non-magnetic water meter provided by European customers, and has been supplied in batches.

(5) Ultrasonic water meter with NB-IoT/loraWAN solution

　　Shenzhen Huaaotong Communication Technology Co., Ltd. was established in 2001. It is the first national high-tech enterprise in China to develop intelligent industrial wireless data communication products. The company has obtained more than 40 international and domestic inventions and utility model patents.

Profit, many products have obtained FCC&CE international certification.

         Hua Aotong provides wireless data transmission modules based on RF chips from different manufacturers, ZigBee and Wi-SUN wireless ad hoc network communication modules, LoRa and LoRaWAN wireless communication modules. For the low-power wireless meter reading applications of water, electricity, gas, and heat meters, Hua Aotong has launched FSK small wireless, LoRa, LoRaWAN, NB-IoT, CAT1 low-power wireless meter reading systems. The system includes metering sensors, low-power wireless meter reading modules, micro base stations, gateways, concentrators, and is equipped with handsets and other related supporting tools for on-site testing, supplementary reading, setting, upgrading, and production testing. The HAC-WE low-power wireless meter reading solution based on HAC08 chip design is a perfect combination of low-power wide area network and low-power LAN. HAC-WE adopts the Hua Aotong low-power wake-up method, which is authorized by the PCT international patent, and uses the Hua Aotong HAC08 RF chip to complete the optimal hardware implementation of the patented algorithm. HAC-WE series wireless low-power meter reading solutions are very suitable for urban and rural wireless meter reading applications in agricultural water transformation. Not only the system has low cost and strong practicability, but also can realize big data collection, two-way real-time, and micro base stations can run online at low power consumption mode.
