A new type of remote intelligent membrane gas meter using NB IoT/LoRa/LoRaWAN IoT communication technology is composed of a common membrane gas meter base meter with built-in motor valve and a controller with communication module. While achieving precise measurement, functions such as automatic meter reading, remote valve control, and tiered gas price setting, data mining analysis, remote self-service query, and payment are completed through the gas comprehensive management platform.
l Longer communication distance and wider coverage
l Star networking, multi-channel switching, and multiple encryption algorithms
l Remote monitoring, multi-channel remote self-service query and payment function
l Reminder of insufficient margin and power supply undervoltage, and indication of meter fault codes
l Leakage, overcurrent, interference alarm, long-term failure to use automatic valve closing
l Gas volume can be overdrawn, and after recharging, the balance will automatically deduct the overdrawn gas volume
l Post payment or pre payment mode selection, pre adjustment or real-time adjustment
l Dual power low power design with built-in lithium battery life up to 10 years
HAC products have been widely used in water, gas, heat, electric power, petroleum, military and other fields. The water, electricity, gas and heat wireless communication meter reading system which is based on the low-power wake-up patent technology has been used for a long time in the domestic and overseas market.
