- 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: Can I get hot water in the water meter?
- The water meter is divided into hot water meter and cold water meter, and the hot water meter is hot water. The cold water meter and the hot water meter all have their own operating temperature range, and if they exceed, they will affect the water meter!
- Q: How do you steal water from a water meter?
- He was a brother to steal water, very simple, is to put the table to the demolition, the sensor (four wire pressure glass round dial below) under any line cut on it. So it can not calculate the electronic part, cool water to go after stealing again however, the base table or accurate measurement. Generally people don't see the base table, but will not go to your house to see. You can try.
- Q: I would like to ask, if the water supply, and at this time to open the tap, there will be gas ejected from the faucet, but no water, intelligent water meters and old water meters will be the same as the word?
- Will go word, want to put out the gas.
- Q: My water meter in the absence of water, water meters on their own table?
- pressure fluctuationSince water is a liquid, the physical properties shown in general are incompressible, but in the water pipe the pressure of the pipeline is higher, and the water will show a certain compressibility. In the tap water pipe, the pressure fluctuation is inevitable, and now we are using the water meter is a mechanical watch, in which water flow generated by the kinetic energy to drive gear, so as to achieve the purpose of water metering. When no water, the water pipe ends are connected in a certain amount of high pressure water are fixed; therefore, when the municipal pipe network pressure rises, the volume of tap water pipe after the table shrinks due to the increase of the pressure, this will have a trace of the water through the water meter, is generated; when the pressure is decreased, the table after the tube in the compressed water with low pressure and expansion, will also have a trace of the water through the water, the difference is this time reversal. As we all know, the general mechanical table in the water is in the drive gear, is turned upside down when the water is in progress under the drive gear reversal, the drag force of water phase is different, although the two head of the same amount of water, but reflected in the reading on the meter is very different. According to statistics, in the absence of air in the pipeline, the resulting water is very small, about 0.5-1m3/ months. Under normal circumstances, the water users will not pay attention to; at the same time, this is also the normal level of measurement results.
- Q: Water meter no reason to turn around, how to solve?
- Many reasons for water rotation, but on the whole can be divided into two: one is the subjective factors, namely subjective causes, such as construction acceptance, human responsibility caused by Water Leakage, original gas gathering, which can strengthen the construction management, improve the staff's work and to improve the level of responsibility. The two is the objective factors, the main characteristics of the water itself, by the characteristics of pipeline and the level of technology development in the external objective factors, on the one hand to work in the future continue to explore the improvement will be improved.
- Q: What is controllable remote wired intelligent water meter?
- Wireless transmitting type intelligent remote transmitting water meter (controllable long-distance wired intelligent water meter)The wireless transmitting type intelligent remote transmitting water meter has functions of data acquisition, processing and storage, and is equipped with a wireless transmitting device to receive signals through a remote receiving device. This table does not need laying line and line maintenance, easy installation, simple construction, but the cost is higher.
- Q: What are the advanced water meters?
- Intelligent water meter intelligent water meter is a new type of water meter which uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption and transfer data and settle transactions. Compared with the traditional water meter, it usually has the function of flow collection and mechanical pointer indicating water consumption, it is a great progress.
- 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: Does the water meter battery affect the water meter?
- Intelligent IC card, mechanical water meter or intelligent remote mechanical water meter influence measurement, affect data remote transmission and intelligent prepayment functionUltrasonic water meter, electromagnetic water meter and other intelligent measuring water meters affect the use function of water meter
