This product adopts a stable and reliable base meter from rotor-type water meter as the measurement basis,uses photoelectric direct reading sensor and LoRa/NB-IoT communication interface,adopts ball valve,and can cooperate with our company’s cloud platform to realize automatic remote meter reading of water meter information.Its design conforms to GB-T778.1～5-2018 standard and《electronic remote water meter》(CJ/T224-2012)standard.
◎ Actively report meter counter periodic timing.
◎ valve closing and opening can be controlled remotely.
◎ Support prepaid and pre-order
◎ With warning system,can send alarm prompts when battery undervoltage,abnormal measurement,pre-purchase and pre-paid reache the threshold.
◎ Can set different emergency water consumption according to different users Built-in memory,with large capacity storage function,can save up to 24 months of frozen data.
