——General Information——

 

Product Features:

1. Microcomputer control technology, highly integrated, stable and reliable.

2. The LCD screen is intuitive and clear, and displays the remaining water volume and the accumulated water volume in real time.

3. Comply with GB / T778.1 , CJ / T188 , CJ / T224 and other standards.

4. Purchase water first, then use water, the water meter will automatically close the valve after use

5. The valve is automatically maintained regularly to avoid clogging

6. Photoelectric communication to prevent the influence of electromagnetic interference on water meter counting

7. The built-in battery automatically alarms and closes the valve when the battery is under voltage, and has the function of preventing water theft, and prompts to replace the battery. After the battery is powered off, the data will not be lost for a long time.

8. The IC card has a long service life, anti-magnetic and anti-static, and can read and write more than 10,000 times.

 

——Product Function——

 

1.One house, one table,record water flow, use water sales software with IC card and card reader

2.Alarm function:When the remaining water is insufficient, the valve closes and alarms. After the card is inserted, the valve is opened to continue to use.

3.Close the valve:The valve is closed when the remaining water volume is zero, and the user can use it after purchasing water again

4.Code unique:Every time a small ball valve is used, the power consumption is low, the pressure loss is small, use micro power consumption design, the battery life 6 years

5.Open and close valves regularly:There is a clock circuit to open and close the valve regularly to prevent the valve from rusting

6.LCD: LCD display, data is not lost when power off

WATER METER

 

——Installation Notes——

 

Installation wiring

(1) Before installation, clear the hemp, sand and other debris in the branch pipe to avoid clogging

(2) All installation positions of the meter should avoid exposure to sunlight, flooding, freezing, chemical and electromagnetic pollution, and be convenient for disassembling and reading

(3) The meter requires horizontal installation. During installation, the arrow on the water meter casing must be consistent with the direction of the water flow. To ensure the accuracy of the flow meter, a straight pipe section with 6-12 times the nominal diameter is required in front of the water meter and 4-6 times in the back Straight pipe
