[product introduction]

Lora wireless intelligent remote transmission electronic water meter adopts AMR angle detection technology, non-contact sampling movement impeller rotation angle to realize water measurement, industrial 16 bit ultra-low power MCU real-time data processing, and uses the industry-leading Lora wireless communication technology for remote data transmission, automatic networking and liquid crystal display. Lora wireless remote transmission intelligent electronic water meter has the characteristics of low power consumption, small starting flow, wide range and long data transmission distance.


[functional features]
● the whole machine adopts ultra-low power consumption power management technology and built-in large capacity and long-life battery, which is convenient for installation and long service life;
● AMR angle and phase detection and measurement technology, without mechanical counter components, directly samples the impeller rotation angle, with high measurement accuracy and high sensitivity;
● patented technology of Lora spread spectrum modulation and forward error correction, with strong anti-interference ability, high sensitivity, long communication distance and high success rate of meter reading;
● support prepayment or post payment, with or without valves, to meet the needs of customers in different use scenarios;
● support supplementary reading of data. Under complex electromagnetic conditions, the data of water meter can be copied by hand;
● wide range display, supporting 5 integers + 5 decimals;
● battery undervoltage alarm, LCD visual real-time display;
● magnetic interference warning: when the water meter is subject to external magnetic interference, the LCD will display "interference";
● during broadcast calibration, the system regularly calibrates the running time of the water meter to make the timing more accurate.
