How to check the balance of water meter

If it is a smart water meter, one way is to swipe the user card, and the other way is to look at the black file. If you want to check the consistency, you can add up the following four small pointers and compare them with the displayed quantity.

If it is a pointer water meter, it needs multi-step inquiry.

The first step is to look at thousands of tons (see Figure 2). The pointer of kiloton is between 0 and 1, so the reading of kiloton is 0;

The first step is to look at thousands of tons (see Figure 2). The pointer of kiloton is between 0 and 1, so the reading of kiloton is 0;

The third step is to look at ten tons (see Figure 4). The pointer of ten tons is between 6 and 7, so the reading of ten tons is 6;

The fourth step, finally look at the tonnage (see Figure 5). The indicator of tonnage is between 8 and 9, so the reading of tonnage is 8;

Intelligent water meter is a new type of water meter which uses modern microelectronics technology, modern sensing technology and intelligent IC card technology to measure water consumption, transmit water consumption data and settle accounts. Compared with the traditional water meter, it only has the functions of flow collection and mechanical pointer display of water consumption, which is a great progress. The intelligent water meter can not only record and electronically display the water consumption, but also control the water consumption according to the agreement.
