Instruction
1
The flow rate of water consumed is displayed on the scoreboard of the water meter. They are of two types: drum digital mechanism and dial. When you work with the first you need to look at the control panel, where the accrued portion of the flow is displayed in the slot. This value and must be recorded. But if you want to know how much spent for the previous period, simply subtract the present (current) value previously recorded figure, and get the result.
2
Cheating a reading device of the second type (with the dial). Panel meter the small dials are arranged in a circle. There is a big arrow that points to the numbers on the outer edge of the meter - it shows tenths cubic meters (one share=100 liters). On other dials report tenths cubic meters (cubic meter=1000 liters), thousands and tens of thousands. At the same time, pay attention to the direction of the rotating arrows.
3
The necessary numbers for the transmission of indications are to the right, separated by a comma and a different color. The numbers on the left indicate the proportion of cubic meters, you also need the ones that show the whole cubic meters, that is located on the right (they change as water consumption).

There are so-called remote reading of meter. For this purpose, a counter is additionally necessary to mount the reed switch (a small electromagnetic device), and the mechanical parts of the meter (the roller, the cog or arrow) is a small magnet. The magnet, with a constant turnover of items, passes next to the reed, which at this time closes the contacts of the external low voltage circuit. By counting the number of pulses (considering their weight) that generated the counter, you can get the volume of water. Correct operation of the device for a certain period of time (day, hour, week, month) number of pulses will correspond to the readings of the built-in counter display.
