Improper routing can reduce or increase the flow of water on the counter.

We have in 90% of the apartments are water meters. Their installation is a necessary measure. If you do not put the metering devices have to pay the inflated standards, plus a step-up ratio. When initial installation or replacement of hydrometers possible intentional not correct appliance installation, wherein attorney just bought water meter readings can inflate.

Surprised? I, too, was a little confused when it told me an engineer for verification of water meters. They confided in laboratory instruments and performed with them manipulation without interfering with the meter itself. In some cases, the flow was considered a plus to 20%. And some believed less. To help you properly set the counters will talk about some of the nuances.

flow divider

Before any water meter has a "mesh."

many people think that it is intended to protect the impeller counter from small stone-and no debris. The main function of this grid calm, to cut liquid swirls, ie water, thereby to minimize the effect of parasitic flows correctly read the volume of water passed through the meter.

If you remove the so-called grid, the liquid flow may not act on the impeller. Which in turn will lead to a distortion of evidence.

Failure to properly route

for sealing Connection between the meter and the pipeline use or paronitovye rubber gasket. Usually rubber technical product manufacturer puts in a box with a water meter. And they have a regular geometric shape as a circle. The inner part of the gasket is cut in such a way that no it does not affect the motion of the fluid. But if maliciously or accidentally install the gasket with a narrowed, the device begins to count wrong.

If such a cut gasket plumber installs to counter the flow of liquid Sause, the speed of water passing through the small gap and increase the impeller can begin to spin faster. Which will lead to the passion transmitted readings.

reverse effect readings at reducing achieve the same seal, but installed downstream of the meter. the total flow rate in the apparatus is reduced, which leads to an underestimation of indications. CAP... But I still did not tell you.

Attention

Before installing the water meter pay attention to the presence of liquid rassektelya and the installation of the factory gasket from the kit of the water meter. Nor any self-made pads. Their cost 1-2 rubles a piece.

I hope I have conveyed to you useful information if this is the case, then let mark plumber "kid-skin"For effort! Thanks.
