Smart remote water meter
——General Information——
Product Features:
1. Built-in CPU, memory chip and 485 / M-BUS communication module
2. Supply power only when collecting water meter data, the word wheel code of the water meter is read by the photoelectric tube, and the number generated by the CPU judgment is output by the 485 / M-BUS
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
——Product Function——
1.Low power design
Since the data of the character wheel is directly read, there is no accumulated reading error. The mechanical reading and the electronic reading are kept consistent .Low power consumption design, only need power when reading.
2.Consistent reading
There is no inconsistent reading caused by accumulated errors or water meter reversal
3.Reliable communication
Using advanced data encoding and verification methods, high communication reliability
4.Code unique
Each table has a unique address code, bus connection, simple wiring
5.Automatic meter reading
Combined with the host computer system to establish a remote automatic meter reading management system to realize meter reading and management automation
6.Electronic reading
Electronic reading device does not affect the measurement accuracy of the original primary instrument
7.remote control
The direct-reading remote water meter can control the switch remotely through the management software. The valve has its own periodic maintenance function to avoid clogging

——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
