LORA Wireless water meter with valve
This type of water meter can be use of detection mode by double reed switch, preventing effectively the error caused by the electromagnetic interference and the pulse jitter.
The communication module is in dormancy mode at ordinary time, it comes to life with a very short time each minute and it detects if there is wireless commands or not. If detected, it starts the receiving function and receives the data; If not, it enters into sleeping mode. By this way, it drastically reduces the average power consumption of the module that effectively prolongs the battery life.
All meters will be guaranteed against defects in workmanship and materials for a period of one (1) year from the date of acceptance.Defective meters or parts discovered within this period shall be replaced without charge upon return to the HBM Meters.
With anti-magnetic interference function that when the two reed switches pick up caused by the magnetic interference, the valve closes off automatically; It automatically opens when the interference stops.
With the battery voltage detection function, it can pass the power-off information to the management platform when the batetry almost runs out, facilitating the administrator to find that;Module with automatic data storage function when power down arises, assuring the data won’t lost when power down, and when the power supply recovers,it is able to continue to work properly.
The joint of the RF module and the base meter uses the integrated structure,with built-in antenna, reducing the damage of antenna in the process of installation.
Detailed
The communication distance of the wireless module can be optimized according to the different demands, peer-to-peer communication distance no less than 1000m(In open field condition, thus,during practical construction, the transfer impedance need to be considered).
Use of LoRa transfer mode that can drastically extend the communication distance after the repeater(s) installed.
The module uses of deep dormancy time design, it is able to completely close the wireless module during the deep dormancy time period(not in operation during night time ), which drastically help reduce the power consumption;
Whole circuit board uses of ultra low power consumption design, power suuply by high capacity lithium battery,battery life over 8 years;
Is able to set up the metering devices by the handset reader and check the original dat a and data from meter reading.
AMI function that the system is able to control the shut on/off of the valve on real time by the help of the valve.
