1product overview

Wireless remote transmission water meter is equipped with a wireless remote transmission module inside the water meter, usingLoRaSpread spectrum technology is used for wireless stable data transmission, which has the characteristics of low power consumption, stable performance, and long transmission distance. It solves the problem of the inability to balance the transmission distance, anti-interference ability, and low power consumption of wireless water meters in the early stage.

IIPRODUCT FUNCTION

Ø Remote meter reading: Through the system, remote wireless real-time meter reading and timed automatic meter reading can be achieved.

Ø Wireless wake-up: It can achieve remote wireless wake-up and respond to real-time processing instructions from the upper computer.

Ø Trigger upload: The water meter module is usually in sleep mode and can be triggered to upload real-time data once.

Ø Self diagnosis: When there is a malfunction inside the water meter, the water meter will automatically record the fault status and upload it as water meter data to the software platform.

Valve controlled water meters also have the following functions:

Ø Remote control valve: The valve controlled water meter can achieve remote control valve function through the system.

Ø Prepaid function: The valve controlled water meter can achieve prepaid function through the backend system and software platform.

Ø Attack valve closure: It has anti magnetic attack function. When the sampling is subjected to external magnetic attack, the meter will automatically close the valve.

Ø Low battery shut-off valve: When the battery voltage drops below a certain value, the module can automatically close the valve and upload real-time data once.

Ø Power off and valve closing: When the water meter is powered off, it will automatically close the valve to prevent accidental or human power outages; After powering on again, the valve returns to its pre power-off state.
