Krom's intelligent gas membrane meter can realize prepayment function and complies with CJ/T 112-2000 "IC Card Household Diaphragm Gas Meter" standard. The realization of prepaid gas meters eliminates the trouble of daily meter reading and can meet the needs of household and industrial prepaid gas meters at different stages of urban gas management. It is an important equipment for gas companies to realize scientific gas supply and automated management.
It can be paired with our independently developed electronic backpack with built-in NB-iot or LoraWAN module. It is a low-power product that integrates measurement, collection, communication and transmission. It can monitor abnormal conditions such as anti-tampering and battery undervoltage, and report them to the management platform.
· High measurement accuracy, high reliability, long service life and wide application range.
· High security factor, equipped with logical encryption card to prevent copying and decoding.
· Micro power consumption, micro-assembly design of the main air board, in line with ISO 7861-1/2/3 standards, the current is kept below 1uA during sleep, and the service life is long.
· Mechatronics design, built-in electromechanical valve, accurate and reliable action. It has a built-in highly integrated control board that has undergone three-proof treatment, and the multiple defense design effectively protects the smart watch.
· Reliable performance, mechanical and electronic components adopt full-life design, and are maintenance-free for eight years. It has anti-magnetic interference, power-off protection, over-current protection, anti-theft and other functions.
· Data storage and display, built-in solid-state data storage, protect data at any time. When inserting the user card or pressing the button, the LCD screen displays the remaining gas volume.

oxygenOperating cost |
Domestic NB card, 10 yuan for 10 years, applies once a day, overseas charges are based on local operators |
Install a 4G traffic card concentrator |
Usage of the Lorawan carrier network is charged on a per-point, annual basis. In places where there is no Lorawan network, building a self-built network requires costs such as gateways, servers, and device management platforms. |
|
Application scenario analysis |
Can be used anywhere with NB-iot signal coverage |
The equipment is far away, the valve point reading can be controlled in real time, and the downstream meter relay can be set |
There is no backbone or supplemental replicas, and the LoraWAN network is used as an overlay network. A self-built network requires the deployment of a gateway |
HAC products have been widely used in water, gas, heat, electricity, petroleum, military industry and other fields. The water, electricity, gas and heat wireless communication meter reading system based on low-power wake-up patented technology has been used in domestic and foreign markets for a long time.
