Generally speaking, the tonnage of water meters starts from the right, corresponding to one, ten, hundred, thousand and ten thousand respectively. Suppose the number displayed on the water meter is 00 1254, and the color of 4 is red, indicating that the tonnage of water used is 125.4 tons.
The first four digits of the water meter are black, and the fifth digit is red, with only three red hands. X 0. 1 next to the red pointer means that the number pointed by the pointer is X 0. 1 ton, and X 0.0 1 next to the red pointer means that the number pointed by the pointer is X 0.0 1 ton, so the above table should be 0.3485 ton.

Precautions:
1. When selecting the caliber of water meter, we should not only consider the pipe diameter at the installation site, but also consider the frequently used flow rate to select the appropriate caliber water meter. It is recommended to use the common flow close to or less than the flow required by the water meter.
2. The installation position of the water meter should be convenient for disassembly and meter reading, and should prevent exposure, freezing and pollution. At the same time, a valve should be installed in front of the water meter so as to disassemble the water meter without water.
3, when installation, should remove the tube linen, ore and other sundry, in case of water stop filter clogging, otherwise it will increase the word value error, and affect the water supply.
4. The water meter should be installed horizontally (except vertical water meter), with the dial facing upwards, and the direction of the arrow on the case should be consistent with the direction of water flow.
