How to read the picture of digital water meter? Can you tell me how much water is used and explain it to the experts?

The first counter-clockwise number of a digital water meter is a black needle, which indicates a number. The digit of the black table is a, so the reading digit is Ax 10, which means the digit of the black table is B.

In general, the reading of water meter is displayed by a combination of black character wheel and red pointer. The structure of reading display is generally that the reading consists of a black character wheel and a red pointer. The black character wheel usually displays integer numbers, and users can only read the numbers on the character wheel. When the water meter leaves the factory, the reading on the pointer is used for inspection. The reading of the red pointer is also used for factory inspection, so we don't have to care.

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.

5. Water meter is a precision measuring instrument, so it should be protected from strong external force during use. Users can't destroy the lead seal and disassemble the internal components by themselves. If they suspect that the indication error is too large, they can submit it to relevant departments for testing.
