- Q: What is the maximum water quantity of a water meter with a diameter of 80mm?
- An instrument for measuring water flow. The cumulative flow of water is mostly measured. Generally divided into the volume of water meters and speed water meter two categories. The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.
- Q: Which direction is the switch for domestic water meter?
- It's a watch side valve. Generally speaking, the counter clockwise is open. Be careful not to force too much, easy to spool broken.
- Q: What's the unit of water for running water?
- On the dial of the water meter, there are several small pointers arranged along the arc. There is a small red triangle in the center. When the tap is unscrewed and the water is flowing, the little red triangle turns. As for those little pointers, no matter the current is not flowing
- Q: How to buy a water meter
- The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.
- Q: Difference between dry water meter and wet water meterWhat are the advantages and disadvantages of the two water meters?
- The counter wet water meter into water, after a period of time of use (especially the poor water quality in the area), the dial is easy to yellow, black, and meter reading effect; the surface of the glass to withstand the pressure, such as water surface of the glass is broken, the water will overflow. When large temperature difference, the glass is easy to produce fog effect of reading and water; when the weather is cold, the water surface in the glass of water will freeze (sometimes the glass burst) will make the water meter, unable to work, the direct damage of the water meter. But these phenomena only occur in many areas in the north of China, and in South China, almost no effect. And the initial amount of wet water meter have a dry water meter and is slightly smaller, because its structure is simple and the manufacturing cost of dry water meter, but also relatively small.
- Q: Installation of water meter for intelligent water meter
- The upper and lower reaches of the water meter shall be equipped with the necessary straight pipe section or its equivalent rectifier. The length of the upstream straight pipe section shall not be less than 10D, and the length of the downstream straight pipe section shall be no less than 5D (nominal nominal diameter of the water meter D). For the eddy current caused by the elbow or centrifugal pump, the rectifier must be installed before the straight pipe section;
- Q: Why is the water meter valve closed and solutions?
- When the remaining water reaches the set alarm amount, the screen shows "valve off"". Brush the user card to open the valve and continue to use the water until the valve is closed. Credit card is recommended to buy water as soon as possible.
- Q: Who will be responsible for the leakage of water before the water meter?
- This year, China promulgated the "property law" and clearly defined, water pipes before the leakage of water by the property responsible for the water meter after the leakage of water by households themselves
- Q: What is the working principle of the code type pre paid water meter?
- Emergency overdraft: according to the needs, operators can set the corresponding amount of overdraft amount, press the start button, users can emergency use. When the emergency dosage is used up, turn off the valve automatically and no longer respond to the overdraft function. After the new amount is purchased, the overdraft amount is deducted first.
- Q: Are the water meters and valves installed outdoors in a well? If so, how about before and after?
- Usually installed in a well, the valve is installed in the water inlet, the water meter is installed behind the valve, when the water meter is bad, the valve can be switched off and repaired.
