Electronic Backpack
Supports remote wireless communication for terminal device data.
Product Description
Featuring a ultra-low-power design and an integrated lithium battery, Zelian Electronics’ wireless data logger is engineered for reliable, long-term underwater operation. It supports RS-485 interfaces to collect data from meters and sensors—such as water meters, flowmeters, and pressure transmitters—and transmits it remotely via NB-IoT and GPRS/3G/4G networks. This robust solution effectively solves the challenges of manual meter reading in harsh underground environments.
Product Advantages
Data Acquisition Function
Collects data from water meters, flowmeters, and other instruments.
Storage Function
Built-in non-volatile memory for circular data logging with power-off protection.
Alarm Functions
Instantaneous alert reporting upon battery under-voltage, or pressure and flow rate threshold violations.
Communication Functions
Supports mainstream cellular networks including NB-IoT, GPRS, 3G, and 4G.
