Product Description
HKT membrane meter, which can realize the pre-payment function, complies with the standard CJ/T 112-2000 "IC card household membrane gas meter". The realization of pre-charge eliminates the trouble of daily meter reading, which can meet the needs of household and industrial pre-paid gas meters in different stages of urban gas management. It is an important equipment for gas companies to realize scientific gas supply and automatic management.
It can match the electronic backpack independently developed by our company, and has built-in NB-iot or LoraWAN module. It is a low-power product integrating measurement, collection, communication and transmission. It can monitor the abnormal status such as anti-disassembly and battery undervoltage, and report to the management platform.
· High measurement accuracy, high reliability, long service life and wide application.
· High security factor, equipped with logical encryption card, preventing copy and decoding.
· Micro power consumption, main air plate microassembly design, in line with ISO 7861-1/2/3 standard, keep current below 1uA when sleeping, long service life.
· Mechatronics design, built-in mechanical and electrical valve, accurate and reliable action. Built-in high integration control board after three defense processing, multiple defense design effectively protect smart watch.
· Reliable, mechanical and electronic parts adopt full life design, eight years maintenance free. With anti - magnetic interference, power - off protection, over - current protection, anti - theft and other functions.
· Data storage and display, built-in solid state data storage to protect data at any time. The LCD screen displays the remaining gas when the user card is inserted or the key is pressed.
Emission current | ≤250mA | ≤130mA | ≤120mA(22dbm) ≤110mA(17dbm) |
Transmitted power | 23dBm | 17dBm/50mW | 17dBm/50mW |
Current Consumption | ≤20uA | ≤24uA | ≤20uA |
Frequency band | NB-IoT dedicated frequency band | 475 ~ 510MHz | (433~510MHz or 863~928MHz)Compatible LoRaWAN® |
Hand-held meter reading | support | support | nonsupport |
Communication distance (line-of-sight) | ≥20Km | ≥10Km | ≥10Km |
Way of setting up | Infrared Settings Upgrade | FSK set | FSK Settings or infrared Settings upgrade |
Low power consumption real time | non-real time | Real-time control meter | non-real time |
Data downlink delay | 24h | 12s | 24h |
Battery life | The ER26500 can last up to 8 years | ER18505 about 13 years | ER18505 up to 11 years |
Base station | Use NB-IoT operator base station, a base station of 50,000 meters | A concentrator manages 5000 water meters with no relay | 5000 tables per gateway, gateway support wifi Ethernet and 4G |
Operating cost | Domestic NB card, 10 yuan for 10 years, reported once a day, foreign fees according to local operators | A concentrator to install a 4G flow card | The use of Lorawan operator network is charged annually for each point. In places where there is no Lorawan network, the self-built network requires gateway, server, device management platform and other costs. |
Application Scenario Analysis | It can be used wherever there is NB-iot signal coverage | The device is relatively far away, and the valve point reading can be controlled in real time, and the downlink table relay can be set | There is no trunk or supplementary copy, and the LoraWAN network is used to cover the network. The self-built network needs to be deployed with a gateway |
