Q:The difference between rotary vane water meter and screw wing water meter
Rotor type water meter rotor type water meter is suitable for small diameter pipeline unidirectional flow measurement. Such as total household water metering caliber 15mm, 20mm specifications of pipe. The water meter is mainly composed of a casing, impeller measuring mechanism and a retarding mechanism, as well as indicator, has the advantages of simple structure characteristics.
Q:What are the sizes of the water meters in general?
Caliber, that is, the diameter of the water inlet and outlet of the water meter. Water meter, rotor type, spiral wing type of two movements. 15mm rotary water meter for general use, low cost, easy to repair. There is also a card type water meter, deposit money into the card, and then use water. In some areas, the water business lobby has this kind of business.
Q:Why does the new water meter have no accuracy grade and where is the accuracy level of the water meter?
The new standard has indeed canceled the ABC level meter before the class, not the so-called a table B scale call, is mainly concerned with the ratio of Q3/Q1 in the water meter dial marked as R-, such as R80, said Q3/Q1 was 80. Then can be used to Q2, Q4 equivalent, specific new standard, say no more.
Q:How can I distinguish water meters from dry ones?. Still wet?.
The biggest difference between dry and wet meters is the metering mechanism. The impeller is separated from the central gear, and the upper end of the impeller is coupled with a magnetic component at the lower end of the central gear by a magnetic component (magnetic ring or cylindrical magnetic steel). When the water flow to drive the impeller to rotate, the magnetic element lower magnetic element and the upper end of the impeller center gear to attract or repel, driving gear synchronous rotation and drive from the center of the water passes through a water meter counter.
Q:Which is better, dry water meter or wet water meter?
The friend's question, in my opinion, is really not very professional. Because in terms of intelligent water meters, dry water meters and wet water meters only have different structures, but not good or bad points. Some people say that the metering wet water meter accurately, initial momentum is small, no demagnetization argument, I think it is an individual phenomenon at the early stage of dry water meter production, and now the dry water meter manufacturer had to solve these problems.
Q:Why should water meter use batteries?
Because of the use of intelligent water meters or remote data water meters, electrical energy is needed to transmit data signals
Q:How does Hua Xu IC card intelligent water meter sound for long time?
Otherwise, the amount of water remaining is insufficient or the water meter is out of order. You can look in the card... If there is an exception, it will show.. Timely notification of property maintenance.
Q:How can one way water meter be controlled by one way?
A one-way control device is installed at the water inlet end of the rotor wet water meter, the inner surface of the device is composed of a water inlet end and the water meter shell with a threaded connection with through hole plug, T valve spool and valve plug in and plug, and set the reset spring valve rod in T valve spool on the form. The spool rod in a movable fit way through the center hole plug in T shape at the top of the valve core is a round table, using the reverse flow of top pressure, so that the cone cone and cone shell inlet end face seal, cut off the water, to achieve one-way control.
Q:Has the number of water meters been accumulating? Should the water use of this month be reduced by last month? Will it be cleared?
Will not be cleared, for example, in January the water meter readings 1120, February degree 1150, then this month the amount is 1150-1120=30 (ton)And the degree of each month will be recorded, do not be afraid of mistake, and now the management is very scientific and technological
Q:Water meter check valve, front and rear should be installed according to it?
According to the specification, the backflow meter shall be installed in front of the municipal water meter, but some of the city's single water inlet only needs to be equipped with check valves.Floor residents do not need to install check valves for small water meters.
