China Photoelectric Wireless Remote Reading AMR Water Meter, Find details about China Photoelectric Water Meter, Wireless Water Meter from Photoelectric Wireless Remote Reading AMR Water Meter
"Gaoxiang" brand wireless remote meter is measuring water flow in pipeline, and has function of wireless data transmission. Through the radio waves to transmit data, and also, waterproof, moistureproof, prevent attacks, prevent stealing water, prevent damage, diamagnetic, anti-jamming and security performance is good, too.
Product Features :
1.Lithium battery,and accurate meter reading
Adopting photoelectric direct reading technology,can read the meter window directly.
2.Convenient meter reading,improve efficiency and reduce cost
--The efficiency is 8 times more than the traditional meter reading
3.Meter built micro-power wireless data transmission module fully digital integrated circuit design which ensure the stability and reliability of wireless data transmission.
4. Data retention and recovery: in case the battery no power, the data can be stored in the water for 10 years, when change the new battery, the data will there and safe.
5.Anti-attack function: water meter with a high reliability sensor, has a strong anti-magnetic attack capability, general external magnetic interference will not affect the normal operation of the meter, while the management system for illegal attacks users can effectively record, alarm tips, etc., to improve the reliability of the product.
6. Display and reading clearly, the base table life will be 10 years.
Module functions :
Wireless wake
Can realize remote wireless wake, real-time response PC processing instruction.
Attack close valve
Has prevention function from electric and magnetic attack, otherwise, the valve will close automatically.
Remote-controlled valve
Can control the valve remotely, to achieve prepaid and postpaid.
Tigger upload
Module is asleep at usual time, can make the module upload the real-time data by tigger.
Low power close valve
when the voltage is lower than a certain data, the module will close the valve automatically and upload the real-time data.
Power off close valve
When the power is off, the meter will close valve automatically to avoid accidential or human damage, when the power is back, the valve will return back to the before states.
Reed switch dailure detection
when one if the reed switch is broken, the meter will upload the damage indicator.
