Q：New home IC card water meter how to choose?
meter is an indispensable water metrology products today, with the
progress of science and technology, an IC card water meter instead of
the old mechanical water meter "light battle" to solve the door meter
reading and charging water problems. Newly
installed household IC card water meter has many types, so buyers have
brought a certain degree of difficulty of purchase. However, to buy IC card water meter friends blindly choose the most,
or look directly to the IC card water meter prices to choose what kind
of expensive election, or direct election cheaper.
This is a very irresponsible way for our suppliers to provide products to their customers. The
newly installed IC card water meter price does not determine
everything, only one-sided decision on some models of reproduction costs
have increased, but does not represent suitable for all users to use. We
take the dry IC card water meter and wet IC card water meter as an
example, these two types of IC card water meter price basically the
same, but if the user blindly choose a random, do not ask whether it is
suitable for their environment. Dry water meter suitable for the northern cold weather, wet water meter for the South water quality. If the northern region to choose wet IC card water meter, then in winter will result in water meter freezing occurs.
Q：Why mechanical meter was eliminated?
the continuous development of science and technology, high-tech
technology is increasingly being applied to our lives, the smart meter
is one of them. Intelligent water meter with its own strong advantage gradually occupied the ordinary mechanical water meter in the market. So, ordinary mechanical water meters and intelligent water meters in the end there is much difference?
Ordinary mechanical water meter, which is commonly used before our home water meter. The
basic principle is to use the pressure generated by the flow of tap
water to drive the rotation of the gear inside the water meter, while
the water meter shows the gear under the disc drives the rotation of the
pointer to count, so as to achieve the purpose of measuring water
consumption, because the price is very low, The role, so the use of a wide range.
most of the ordinary mechanical water meters are indoors. When the
water management department wants to meter the users, it is difficult
for the users to ensure that they are at home. Therefore, it will
increase the number of non-meaningless workloads Running, because it is manual meter reading, but also very easy to
charge less, more charges or even no fees and other phenomena, and if
the water meter to the outdoors, management is relatively convenient a
lot, but with the attendant problems also will follow.
of all, because many water meters are made of copper, there are many
unscrupulous businessmen who steal table sales at night. In winter, the
temperature of the glass case is too high, causing a lot of water
leakage and thus causing losses to the water company. There is a large mechanical wear and tear, it is easy not allowed or broken.
Q：Regular water meter maintenance
after the long-term use of the smart meter, there will be some scale,
and these ditches formed in the smart meter can easily lead to smart
meter measurement error, and may even lead to transmission errors. Therefore,
regular maintenance and selection of smart meters are crucial. Regular
cleanup is a necessary maintenance step when using smart meters. When
using them, care must be taken to ensure the cleanliness around the
smart meter when using them. Avoid
some acid-base substances on the smart meter corrosion, but also to
ensure that during the moisture-proof, which will lead to intelligent
meter damage caused by the error, and even led to the smart meter
damage; above the smart meter can not Place
things, because the long-term placement of things will result in damage
to the smart meter, if found in the smart meter has a problem, found a
bad state, do not open the smart meter seal, privately operated is
likely to lead to intelligent water meter The permanent damage, so it will give users unnecessary losses. Smart
meters in the transport process to ensure that it is placed when placed
horizontally, after all, a smart meter is an instrument, not only to
ensure that it can be used, but also to ensure that it can accurately
measure and transmit data.
Q：What factors should be considered when choosing a meter
Smart meter is discounted, is its value worthy of this price. Many of us do not know what kind of water meter we are right to choose
from, and today we come to understand what factors should be considered
when choosing a water meter.
meters must be included in the building should be installed on the
introduction of water meter; building a certain part or individual
equipment must be included in the water pipe should be installed on the
water meter; residential building should be installed household meter .
first thing to consider is the corresponding meter diameter, according
to their own caliber to choose the diameter of the meter with the
accompanying, so as to ensure the smooth installation and flow of normal
Under normal circumstances, the pipe nominal diameter less than or
equal to 50 mesh should be used rotor-type water meter, nominal diameter
greater than 50mm should be used when the screw-wing water meter. In rotor-type dry and warm water meters, wet meters should be preferred. The following principles should be considered when determining the nominal diameter of a water meter:
When the water is uniform, should be designed to flow no more than the
rated flow meter to determine the nominal diameter of the water meter. When used as a living (production) or fire fighting system, the rated
flow of the meter does not include the flow of firefighting fluid. The
firefighting flow should be verified and the firefighting flow rate
checked so that the total flow does not exceed the maximum flow rate
limit of the meter.
2. When the living (production) water is not uniform water, and its
continuous peak load every day and night does not exceed 2 ~ 3h,
according to the design of the second flow is not greater than the
maximum flow meter to determine the nominal diameter of the water meter.
3. Newly built residential household water clothing, the nominal
diameter of the general can be 15mm, but if the residence is equipped
with self-closing toilet flushing valve, in order to ensure the
necessary washing intensity, the nominal diameter of the water meter
should not be less than 20mm.
to consider the pressure loss of the water meter, the pressure loss of
IC card water meter measuring accuracy is higher. Once
again to consider the water meter range ratio, the range ratio is the
main reason leading to the price of water meters, IC card water meter
range than the gap, 200: 1 to 500: 1 have. The last thing to consider is the use of functional requirements of
the environment, according to their actual needs to choose prepaid,
remote valve control, waterproof, anti-attack and other functions.
purchasing IC card water meter must be based on the above factors to be
evaluated, not only to look at the price and underestimate the quality
of the water meter itself, in the purchase must be combined with their
own actual situation to be assessed, after all, is their own is the best.
Q：Smart meter card how to use?
smart electronic water meter is very simple to use, when the users
amount of water dropped to a certain value, the computer module speed
alarm sound, suggesting that users should pay card to buy water. If
more than the amount of water, the computer module will automatically
shut off the electric control valve, cut off the water supply. Until the user has inserted the IC card has been re-open the valve for water supply.
From the users point of view, is the IC card card plug in the water meter. IC
card water meter work process is as follows: The IC card with the
amount of money into the water meter kind of IC card reader, the
computer module to identify and download the amount of money, the valve
opens, the user can use water. When the user is
using water, the water collection device starts to collect the water
consumption and converts the required electronic signal into the
computer module for measurement, which is displayed on the LCD display
Q：Water meter manufacturers how to test the water meter?
the type of water meter is varied, but whether it is mechanical meter,
smart meter, IOT meter or remote meter, are used for national legal
water transfer settlement voucher. According
to the relevant provisions of Chinas Metrology Law, the water meter
belongs to the national compulsory appraisal measuring instrument. Each
water meter must pass the first inspection, sampling inspection, bench
inspection and third-party testing before it leaves the factory.
Otherwise, it will not be used. The test of the water meter is a compulsory test, so how does the water meter manufacturer test the water meter?
meter test refers to a test of a new water meter that has not been
tested to determine whether the metrological performance of the new
water meter complies with the relevant requirements of the national
standards and industry type approval and is based on the relevant
provisions of the Metrology Law It is also necessary to carry out the first inspection. National
Ministry of Construction also need to verify the meter for review,
there is no test of the meter, it can not be accepted. Water
meter manufacturers to test the progress of progress from the water
meter manufacturers to undertake the work of the quality supervision
departments to submit an application and submit inspection, the first
inspection pass, the certificate issued by the quality supervision
department, and paste the water meter certificate.
