Common types of meter and how it works

Water meter on the water pipe, the water meter dial arranged along an arc of several small pointer, Central has a small red triangle, unscrew the faucet when the water flow when the red triangle will turn up. As for those little hands, regardless of the water does not flow almost motionless.
The dial also says the words “m3″, namely cubic meters of meaning. That is, the reading table in units of cubic meters. Because each cubic meter of water happens to be a ton of reading it is directly tonnes, so water can be easily read by the total amount of water (tonnes) calculated.
So what the meter works is it? Actually very simple, because the meter housing is fixed, its internal volume is fixed, while the water is flowing, it pushes a rotating impeller, whenever the impeller rotates in a circle, there is a constant volume of water flowing through. Therefore, if the number of turns of the rotation of the impeller cumulative down, multiplied by the constant volume, you can get the total amount of water flowing through.
We have clear principles, then look at the specific water meter inside what it is, because in order to prevent users from cheating, have seals on the cover, not allowed to open.

Internal structure from outside to inside the meter housing can be divided into the sleeve, the inner core of the Big Three. Housing is cast iron, the water came out from the inlet through the lower portion of the annular space of the housing, here called “Under the donut.” Above this annular space has “the donut” and outlet connected. Bottom of the sleeve there is a small hole with a filter, filter out debris in the water. There are two rows of the upper and lower side of the sleeve hole, the position of the hole coincides with the upper and lower ring chamber housing front, obviously, the lower is the water hole, the row is the water hole. Of particular note is that the two rows of holes are along the circle tangential direction at an angle to play, it works as shown in the animation. Note down two rows of holes opposite direction. Water flows from the lower row of holes into the tangential direction, is bound to form a revolving flow, which for the water meter work is very important.
Impeller shaft vertically upwards to the middle, there is a small gear shaft above, and use it to “Decimal gear” engagement, the purpose of the cumulative number of revolutions. Role “Decimal gear” is the single digits whenever gear turn ten laps, ten digit gear on the revolution. In other words, the single digits gear revolution, tens gear to turn out the circle. Single digits gear is active one, is sufficient to drive the tens gear. Virtually every decimal one gear complete with two pairs, so that the rotation in the same direction in which a pair transmission ratio is 9:30, and the other pair is 10:30, two pairs connected in series, the overall ratio is this the product of the two, i.e., 0.099999, can be approximated as 0.1.

On this basis, if you want to read the seven digits (the decimal point before reading four black graduation, three decimal places read red scale), you have to use 12 pairs of gears. Plus some other purpose, in the middle of this small space to squeeze in 18 axes and 34 gears, can also be regarded as a high-density mounting.

Meter time of purchase should pay attention to the details

Modern homes often use the meter, but we understand the basic knowledge of the water meter is very small, the following inventory for everyone before the purchase and use of the meter we need to know the basics. Not all meters on the market are qualified, if we do not pay attention in the selection of the meter when the details, buy a home water meter often be biased, so that the recording error occurs when we use water cube.

Under normal circumstances we must first focus on the meter case. The case of a direct impact on meter accuracy and service life, a lot of the case by the poor quality of the water meter in a long dark environments prone to large errors, life is also very low, I suggest that you buy when the choice up to the national standard of water meters. A lot of people do not look at the water meter, which also led to a number of water meters to be deceived personnel records each month to pay a large amount of water, we can directly purchase water meter consult sales staff correct viewing method, so that you can avoid being taken up. Under normal circumstances the meter can be divided into two types. Speed ??volumetric water meter and water meter two meter for different users, each with advantages and disadvantages, consumers can choose specialization according to the characteristics of the city and their own situation.

Finally, we must choose the time of purchase with the CMC meter mark, which means “People’s Republic of China manufacture and repair of measuring instruments” English abbreviation. Also after the purchase we will want to ask the seller a regular machine-printed invoices, so if the product quality problems within the warranty period can be repaired.

What is the reason for rotation meter

First, your home indoor air duct, the second is to say PPR pipe belongs to a class of plastic pipe fundamentally, it itself has elastic deformation coefficient is much greater than steel, will produce the balloon effect, in this case, it would have been difficult to compression in such a water pipe can become “compression”, and if the home PPR pipe laying for too long, resulting in the probability meter rotation will be bigger.

Because of these two reasons, when the main water distribution network KFS generating pressure fluctuations, will be divided into two cases to make rotation meter, (1) if the competent pressure, there will be a small amount of water entering your home through the water meter pipe, the impeller forward produce water, (2) when the pressure is reduced in charge, you charge the household had a small amount of water will flow back into the main channel through the water meter to the water company do “contribution.”

To prevent stealing water, and now the water meter have several, one is the anti- “inverted” water meter, water meter is not only forward reverse rotation meter billing means that water enters your home, this meter is doing ” addition “, on the contrary, when the water out of your home when the meter is not an anti-assignment billing as a” subtraction “; I heard there is a more peculiar meter, both positive and negative water flow through the meter, it can forward billing, design What is the purpose of this meter is it? I think it might be the water company to prevent the installation of indoor water meter stolen, as far as I know do have indoor water meter installation will steal water meter reversed, of course, this approach requires that the water to steal a little old-fashioned two-way rotation meter job.

Meter Common Problems and Solutions

Under normal circumstances, the most common problems is the water meter measurement are not allowed. Here we suggest that you have to buy excellent quality goods was not to seek cheaper, or if there have been inaccurate readings of the situation in the future use of the process, losses will be even greater. There have been inaccurate readings case we do not open their own water meter to check if the improper operation may result in a substantial increase in the amount of water meter, to when there is unspeakable, and then we can contact the relevant units, so they sent professional staff for inspection. Generally divided into two ways, the first part of your water meter water companies under the jurisdiction of another case belong to the management of water supply business.

Sometimes we find that even in the case where we do not there will be cases of water meter rotation pointer, the pointer will appear even reverse signs. At this point we do not have to worry too much, it is not necessarily a problem with their meter. Perhaps because of the higher water pipe air pressure caused.

Over time it will be automatically restored, so that the pointer rotation and reverse the situation usually very small amplitude, read your water meter readings will not have a huge impact. If your home water meters long without the use of a substantial move, then the time is probably a problem with the meter, they should get in touch with the relevant institutions, home inspection and maintenance.

Use common sense meter

Although many people use the meter but do not understand the basic knowledge of meter, under normal circumstances the national standard diameter water meter is 15 ~ 20mm. Although not a water meter loss of goods, but in order to guarantee the accuracy of the meter is recommended you to a six-year period with the change in time of the meter, so as to guarantee the accuracy of the number water meter walk.

If you want to extend the life of the meter, some small tricks we can use in our daily lives. For example, in the cold winter, low temperatures meter can easily be damaged by frost, resulting in inaccurate readings of the situation. Then suggest that you can make to a meter, “coat”, it can be “cold and warm.” If your home’s water meter placed in the stairs or ventilation, protective measures should do more to close the window, do not let the cold air to the accuracy of the meter.

Currently on the market very much the type of water meter, a mechanical water meter, water meter card, the jet of cold water, dry direct-reading meter, etc., different strengths and water meter price is not the same, you can choose according to specific circumstances. To buy time to follow the following principles: difficult to scale, reduce pollution, accurate, easy to read a lot of copy meter because of the quality, but off the case, use a long time prone to fouling, affecting the life of the meter. Meter accuracy whether or not we need to focus on showing the primary factor in the purchase of water if the water meter readings are not allowed, it will bring you economic losses. Although many meter more powerful, but also more beautiful shape, but the copy read is very troublesome, it is easy to buy a copy of the water meter reading can give us save a lot of time.
