Shenzhen HAC Telecom Technology Co., Ltd. products

HAC-NBt meter reading system is the overall solution of low power intelligent remote meter reading application developed by Shenzhen HAC Telecom Technology Co., LTD  based on NB-IoT technology and Bluetooth technology. The solution consists of a meter reading management platform, a mobile phone APP and a terminal communication module. The system functions cover acquisition and measurement, two-way NB communication and Bluetooth communication, meter reading control valve and near-end maintenance etc to meet various requirements of water supply companies, gas companies and power grid companies for wireless meter reading applications.

The HAC-MLLW LoRaWAN dual-mode wireless meter reading module is developed based on the LoRaWAN Alliance standard protocol, with a star network topology. The gateway is connected to the data management platform through a standard IP link, and the terminal device communicates with one or more fixed gateways through the LoRaWAN Class A standard protocol. The system integrates LoRaWAN fixed wireless wide area network meter reading and LoRa Walk-by wireless handheld supplementary reading. The handhelds can be used for wireless remote supplementary reading, parameter setting, real-time valve control, single-point reading and broadcast meter reading for the meters in the signal blind area. The system is designed with low power consumption and long distance of supplementary reading. The meter terminal supports various measurement methods such as non-magnetic inductance, non-magnetic coil, ultrasonic measurement, Hall sensor, magnetoresistance and reed switch.

This is a half duplex 8-channel indoor gateway product, based on LoRaWAN protocol, with built-in Ethernet connection and simple configuration and operation. This product also has built-in Wi Fi (supporting 2.4 GHz Wi Fi), which can easily complete gateway configuration through the default Wi Fi AP mode. In addition, cellular functionality is supported. It supports built-in MQTT and external MQTT servers, and PoE power supply. It is suitable for applications requiring wall or ceiling mounting, without the need to install additional power cables.

HAC-MLWA non-magnetic inductive metering module is a low-power module that integrates non-magnetic measurement, acquisition, communication and data transmission. The module can monitor abnormal states such as magnetic interference and battery undervoltage, and report it to the management platform immediately. App updates are supported. It complies with LORAWAN1.0.2 standard protocol. HAC-MLWA meter-end module and Gateway build a star network, which is convenient for network maintenance, high reliability and strong expansibility.

HAC-NBA not-magnetic inductive metering module is a PCBA developed by our company based on the NB-IoT technology of the Internet of Things, which matches the structure design of the Ningshui dry three-inductance water meter. It combines NBh’s solution and non-magnetic inductance, it is an overall solution for meter reading applications. The solution consists of a meter reading management platform, a near-end maintenance handset RHU and a terminal communication module. The functions cover acquisition and measurement, two-way NB communication, alarm reporting and near-end maintenance etc, fully satisfying the needs of water companies, gas companies and power grid companies for wireless meter reading applications.

The pulse reader HAC-WRW-D is used for remote wireless meter reading, compatible with all Diehl dry single-jet meters with standard bayonet and induction coils. It is a low-power product integrating non-magnetic measurement acquisition and wireless communication transmission. The product is resistant to magnetic interference, support wireless remote transmission solutions such as NB-IoT or LoRaWAN.

HAC-WRW-A Pulse Reader is a low-power product that integrates photosensitive measurement and communication transmission, and is compatible with Apator/Matrix water meters. It can monitor abnormal states such as anti disassembly and battery undervoltage, and report them to the management platform. The terminal and gateway form a star shaped network, which is easy to maintain, has high reliability, and strong scalability. Option selection: Two communication methods available: NB IoT or LoRaWAN

R160 non-magnetic coil measurement wet type wireless remote water meter, it uses non-magnetic counting function to realize the electromechanical conversion mode, built-in NB-IoT or LoRa or LoRaWAN module for data remote transmission. The water meter is small in size, high in stability, long in communication distance, long in service life, and IP68 waterproof grade. The water meter can be remotely managed and maintained through the data management platform.

Through camera technology, artificial intelligence image recognition technology and electronic communication technology, the dial pictures of water, gas, heat and other meters are directly converted into digital data, the image recognition rate is over 99.9%, and the automatic reading of mechanical meters and digital transmission can be easily realized, it is suitable for intelligent transformation of traditional mechanical meters.
