- Q: Card inserting water meter and method of use
- The card is placed in the sensing area of the corresponding water meter, and the water meter reads the amount of water available in the card, and then opens the valve to provide normal water supply. When the amount of water available in the water meter is used up, the valve is closed, and the user carries the card to the water sale point to buy water, and then the prepaid user card is placed in the water meter induction area to repeat the first process.
- Q: How do you calculate the water meter inversion?
- The inversion of water meters can be divided into two aspects: what are human beings and external forces?.The water meters used in daily life are divided into two major categories. The first category is the ordinary mechanical water meter, drip proof water meter, etc. the second kind is the intelligent IC card water meter, remote water meter and so on. Because the anti reversing performance of the intelligent water meter is very good, the phenomenon of water meter reversal mainly appears in the ordinary water meter. First, the human factors in the reversing of the water meter indicate that the reversal is caused by human beings. Because the method is very simple, as long as the water meter is removed, the installation can be reversed. The installation will make water meter readings go backwards, causing huge error meter measurement, a method which is currently the most direct fee evasion.
- Q: Water tonnage data show a sudden increase in a lot of what is the reason
- A water meter is an instrument for measuring water flow. The cumulative flow of water is mostly measured.
- Q: Pratt & Whitney tip: smart water meter is not out of the water, how to do?
- In the face of water intelligent water meter, excluding the impact of external factors such as water, should be timely check the remaining water into the user card, when everything is normal and water balance is adequate, part of LCD display the remaining water and the "valve" signs; when the display is "valve off", "alarm", that the remaining water is insufficient, the user the user must hold the card to buy water buy water, complete recharge card to open the valve, water meter to water again. When the internal power supply power shortage, LCD will display "under pressure" and "off valve", for the first time that can be inserted into the card user to re open water supply valve, the battery can continue to keep the supply of around 24 hours, users should notify the maintenance personnel to replace the battery as soon as possible. The amount of water used up, the battery power shortage, man-made attacks or failures. When the water quota is used up, the battery is short of power and the people are attacked, the intelligent water meter valve is automatically closed. The utility model belongs to a normal condition, and the water meter and the valve can be automatically opened when the water is purchased, the battery is changed or the utility model is attacked and cleaned. If the intelligent water meter fails, such as sealing is not good, resulting in partial damp or water inlet, valve fouling, resistance increases, etc., water meter valve will not open. The emergence of this situation is directly related to the design and quality control capability of intelligent water meter manufacturers, which can be avoided from the existing technology.
- Q: Is there any deviation in the water meter measurement? Why?
- Water meter is the only measuring instrument for the water supply enterprise and the user to settle the trade. It is the main basis for the water users to collect the water fee. The deviation of water meter measurement will have a negative impact on water supply enterprises to improve water rate recovery and reduce production and sale rate, and will easily cause disputes between water supply enterprises and users. Talking about the causes and Countermeasures of metering deviation of water meter in light of practice.
- Q: Who will be responsible for the leakage of water before the water meter?
- In accordance with the relevant provisions of the commercial housing pipeline warranty period of 2 years, in the warranty period, the construction enterprises responsible for maintenance, such as the formation of economic claims, but also by the construction enterprises.
- Q: Where is the backflow preventer installed?
- The backflow preventer must be installed horizontally, the installation site environment should be clean, there is enough space for maintenance, safety or drainage device (air blocking device) from the ground of the main export is greater than 300mm, is not submerged in water or sundries.
- Q: The difference between rotary vane water meter and screw wing water meter
- Level Woltman meter: the level of Woltman water meter for the total flow measurement of large flow pipe. It is particularly useful for water supply pipeline and large factory mining content. The main characteristics of large flow capacity, small volume, compact structure, convenient operation and maintenance.
- Q: Why should water meter use batteries?
- You use a smart meter bar, water meter is divided into two kinds, one is direct reading type, one is both direct reading and can send information, you may use the latter, the inquiry function needs power
- Q: Why doesn't the water meter turn around?
- The pipe is in air and cannot be ruled out. As the pipe network maintenance, disassembly and water meter when water supply is stopped, the air into the pipeline, stay in the pipeline is not common; especially some users network will not change the line, pipeline, tap water before the blocked, and the internal pressure imbalance, causing water to move.
