Characteristics of wireless pulse valve controlled remote water meter:

Equipped with anti dismantling, anti cutting, anti magnetic interference and other destructive measures;

Easy installation, convenient maintenance, and cost savings in construction;

Real time monitoring, remote meter reading, and remote control of water meter status can be achieved remotely;

Compared to 3G and 4G cellular networks, LoRa technology has strong scalability and high cost-effectiveness when applied to water meters.

Key technologies: Intermittent pulse sampling technology: converts periodic mechanical pulse signals into electrical signals for sampling and measurement, adopts the "dual reed tube counting" method, improves the installation structure of reed tube relays, and combines software filtering technology to ensure complete synchronization between mechanical counters and electronic counters LoRa spread spectrum communication technology: It has the advantages of high anti-interference, high reliability, high sensitivity, and long transmission distance WOR electromagnetic wave wake-up technology: instantly wake up the water meter to be in communication state, and automatically restore to ultra-low power consumption state after meter reading is completed PWM valve control technology: using pulse width modulation method, effectively reducing the large current generated at the moment of valve action and extending the battery life TDMA time division multiple access technology: a reasonable TDMA (time division multiple access) backoff algorithm to reduce the probability of data collision Fully sealed design technology: adopting new nano coating technology, no exposed electrodes, good sealing performance, ensuring stable operation of the circuit board in humid environments.

Advantages: It has anti dismantling, anti cutting, anti magnetic interference and other destructive measures; Easy installation, convenient maintenance, and cost savings in construction; Real time remote monitoring of water meter status, remote meter reading, and remote control; Compared to 3G and 4G cellular networks, LoRa technology has strong scalability and high cost-effectiveness when applied to water meters.
