Характеристики
Function description:
Sampling measurement
Various sampling methods can be realized, such as dry reed tube, hall and other pulse sampling methods and photoelectric sampling methods.
Valve control
The upper computer can control the valve operation of the gauge by prefabricating the command.
Attack close valve
When the table is under magnetic attack, upload the data frame and set the attack state, and close the valve.After the attack disappears, upload the data frame and open the valve.
In place to detect
With switch in place detection function, when the normally open contact is in place and closed, the table switch valve is in place, the valve can be stopped immediately
Time to upload
The module automatically uploads one frame of table data every 6 hours
Trigger the upload
The module is usually in standby state, which can be triggered to make the module upload real-time data and work status once.
Valve fault detection
Automatically identify whether the valve limit switch is normal. When the limit switch fails, the valve state position is abnormal, and there will be an alarm in the background.
Dry reed tube fault detection
When the fault occurs in the sampling reed tube or hall element, the meter will transmit the prompt of fault in the reed tube, and the meter will not be measured any more. The meter will be measured normally after the fault is eliminated.
Infrared communication
Infrared communication can be used to set the table address, table base and LoRaWAN's secret key and other parameters.

1、Before the installation should first clear the branch pipe of hemp, sand and other sundries, so as not to cause the plugging fault of the water meter.
2、All parts of the IC card water meter shall be installed in a position to avoid exposure to sunlight, flooding, freezing, chemical and electromagnetic contamination Dye, and convenient disassembly, meter reading, and credit card.
3、The IC card water meter is required to be installed horizontally, and the arrow on the water meter housing must be in the same direction as the water flow
4、In order to ensure the accuracy of the flowmeter, it is required to leave 6-12 times the nominal diameter of the straight pipe section in front of the water meter.
Straight sections with 4-6 nominal diameters are left at the rear
