GC-SS21 Micro Power Wireless Water Meter Module
The GC-SS21 module is a low-power wireless communication module independently developed by our company for mechanical water meters. It converts the me
Product details
1Module features
ØLong communication distance and strong penetration ability
Sight distance unobstructed transmission distance greater than 1000 meters, ordinary floor slabs can penetrate 5-8 floors
ØLow average power consumption
Calculated based on transmitting data once a day, the average current of the quasi real time communication module (8-second wake-up cycle) is only 15uA~20uA
ØEquipped with remote meter reading, real-time valve control, prepaid management and other functions
Combined with our company's intelligent water meter management system, it can achieve functions such as data collection of water meters, real-time control of valves, and prepaid management of water meters
ØReal time monitoring function for water meter faults
When the water meter experiences events such as battery undervoltage and magnetic interference, the wireless module will automatically transmit the event to the intelligent water meter management system, thereby achieving real-time monitoring of water meter faults
ØSupport tiered water pricing
By relying on a stable low-power wireless network, complete water usage data can be transmitted to the intelligent water meter management system, providing good technical support for the implementation of tiered water pricing
