How to read the IC card smart water meter?
The IC card water meter consists of a base meter (sending remote water meter), a microcontroller (single chip microcomputer), a metering module, a power supply (usually a battery), an IC card reader, a communication interface, an LED/LCD display block, and a microcomputer control module , Valve control mechanism.
1. "M3" means the unit of measurement (cubic meter)
2. The scale of the "red meter" indicates the measurement reading after the decimal point. Below the table are four meters of 0.10.010.0010.0001. When the water meter displays 6562 in the "red meter", it means that the reading of the water meter is 10.6562 tons.
3. Don’t worry about the red character wheel. Start from x1, x10, x100, and x1000, which are ones, tens, hundreds, and thousands. For example, x1 is 5, x10 is 2, and x100 is 3. Then The reading is 325. Every small reading of each gear, for example, the needle of the x10 gear is on the side of 3 but does not reach 3, then read 2, and the other gears are the same.
F&Q
1. What is the battery life?
Regular use of ER18500 battery, 4500mAh, frequency of meter reading every 3 days, battery life can reach 4-6 years.
2. Protection level?
At present, the perpaid water meter adopts the full potting and sealing technology, and the silicone gel package circuit board part is used, and the battery insertion opening is also sealed to achieve the IP68 protection level.
3.What if the water meter is broken?
We will advise customers to purchase a certain number of spare water meters when purchasing in bulk. When problems occur, they can be replaced first, and then the problem water meter will be sent back to the manufacturer for confirmation and repair.
4.Will the valve block？
The water meter valve is automatically cleaned once a month to prevent blockage.
5.Logo?
Yes.we provide the free design for your logo on water meter dial,and package.OEM/ODM Service?With more than 10 years OEM&ODM experience for famous brand ,we can provide the services.
6.Agent？
Yes,We need partners.
