1. How do I select the size of the water meter?
    The most basic consideration for the choice of water meter size is the diameter of the pipe in which the pipe is installed. Generally, the small-diameter water meter can be directly arranged according to the nominal diameter of the pipe. However, under the same diameter, the prepaid water meter has a large structure due to its complicated structure. The pipe spacing replaces the joint pipe fittings for adjustment; the size of the large-diameter water meter needs to be determined according to the flow velocity of the water flow in the pipeline and the size of the commonly used flow, so as to avoid damage to the water meter caused by excessive load. (The same type of hot water meter and cold water meter are the same sizes)
  2. What are the components of the smart water meter?
    The smart water meter consists of a signal base meter, the main control circuit, and a water meter valve.The base signal is to install a signaling device in an ordinary mechanical water meter to provide a metering signal to the electronic main control circuit of the water meter to realize the automatic measurement of water.

    The main control circuit is used to control the switching of the water inlet valve to achieve the purpose of controlling the water for consumers.

    The switch of the water meter valve refers to the fact that the CPU turns on the switch electrical circuit according to the switching condition. The detection of low voltage power is a very important problem for the system of the single-chip microcomputer. To some extent, it can ensure the reliability of the system. Run, avoid the role of data transmission errors.

    The information display of the electronic water meter can be completed by the serial liquid crystal module. The serial liquid crystal module and the CPU have a simple interface, occupying only three interface lines, and greatly saving resources.

  3. What are the standards available for water meters?
    IS 779, IS 6784, ISO4064 (Three parts), OIML R49 and EEC directives are available for
    specification, installation and testing.
  4. What types of end connections are available for water meters?
    Threaded ends with nipples are available up to 50mm water meters. Above 50mm, water
    meters are generally having a flanged end connection.
  5.  What is meant by “domestic” water meter?
    According to different standards around the world, all meters up to 50mm are called “domestic” water meters and
    higher sizes are called “bulk” water meters.
  6. How do I ensure the quality of water meters?
    Water meter is a kind of legal measurement product commonly used by residents worldwide. Therefore, the quality&accurancy of the water meters directly concern the vital interests of the water supply party and the water consumers. In order to ensure the quality of water meters, the water meters produced by Yomtey are all certified by ISO9000 quality system. Every production process and every water meter in YomteY is guaranteed, the quality is very reliable. Under the correct use and proper installation, there will be no problems and the repair return rate is very low.
  7.  What are the important tests on water meters? How much time will it take?
    Accuracy at different flow rates, pressure tightness, and pressure loss tests are the initial
    verification or routine tests that are conducted on every meter. Model approval Tests involve
    prolonged continuous and discontinuous tests mainly to check the durability.
    Initial verification tests can be completed within a day whereas the model approval test will take
    around two months.
  8.  Can I replace my old water meter with a new one of the same size from a different
    manufacturer?
    It is possible, in general. However, it is better to check the length due to alternate lengths of the
    meter permitted in different standards.
  9.  What is AMR? What is its significance?
    AMR stands for “Automated Meter Reading”. An attachment is provided on the conventional
    water meters, to produce electronic output. This electronic output can be transmitted to
    remote locations through wired or wireless technologies. AMRs are not generally adopted in
    many countries. Hence, the suitability of the available AMR units in your local conditions is to be studied.
  10.  What will be the approximate life span of a water meter?
    The life span of a water meter depends on design and field conditions. In the absence of any reliable study, the life span can be taken as more than 10 years.
  11.  How can we repair or maintain water meters in the life span?
    As the spare parts of the meter are not standardized it is advisable to enter into a contract with
    the manufacturer, for repair and maintenance of the water meters. Most of the utilities enter
    into a maintenance contract with manufacturers during the purchase stage itself.
