Q:Who is responsible for the lack of water meters leading to more water use?
The pipeline pressure fluctuation. Water as a liquid, there can be compressed in water supply pipeline pressure is high. The pressure fluctuation is inevitable in tap water pipeline, when the pressure of the main network rises, after the water in the pipes because of increased pressure and volume reduced, this will have the trace of water through the water table generation is transferred, inversion pressure net charge reduced. Because water resistance is greater than the internal gear is reversed when forward resistance, even if the same amount of two water meter, water meter is reflected in the reading on the will also have differences, the total performance is positive.
Q:Why does the new water meter have no accuracy grade and where is the accuracy level of the water meter?
The accuracy level and measurement level of water meter are two concepts. The accuracy grade provides the indication error limit of water meter, and the 2 stage indicates the maximum indication value of water meter, and the error can not exceed 2%. The new procedure has 1 meter water meters, but it must be marked on the water meter. Measurement level is divided by the demarcation of the water gauge and the minimum flow rate to characterize the sensitivity of the water meter. The old rules are graded according to A, B, C and D, and the D level is the highest requirement. New procedures, dosage, process ratio (Q3/Q1) to replace the original level of measurement, the ratio of at least 20 options, the greater the ratio, the higher the requirements, the greater the difficulty of manufacture. The Q3 and Q3/Q1 values of the water meter are determined by the manufacturer according to the market demand, and must be clearly marked on the water meter. When the water meter is checked, the flow point can be selected according to the value indicated on the meter.
Q:Copper valve, screw valve, copper lock valve difference, which should be in front of the water meter, which should be in the water meter after their role?
As for the thread valve you said, I'm not sure what it is, but the thread is a connection. The DN15-DN32 is threaded, and the bigger DN40-DN300 is the flange connection
Q:What's the unit of water for running water?
So the water can be conveniently according to the total water readings (tonnage) calculated.
Q:Who's in charge of the water meter?
The water meter is a user account for water (if it is commercial housing user water meter is the real estate developers to open an account and deposit 100 yuan of water) by tap water company for the purchase and installation of the water meter, the ownership or user.
Q:Is there any deviation in the water meter measurement? Why?
• causes of measurement deviations• water meter problem- water quality issues: (1) the water meter is not the regular manufacturers of water meter, water meter fittings unqualified (2) when the factory is not verification or verification is not qualified; nor do correction; or verification device itself is not qualified (3) class a meter accuracy old enough. This will inevitably result in water meter measurement deviation.
Q:What is the working principle of the code type pre paid water meter?
Prompt function: with input data error indication, battery shortage indication, actuating mechanism closing indication.
Q:How to use a water meter card?
Card IC card chip on the surface of the user after the account, to buy water card to buy water (minimum amount of 20 yuan each to buy water above), opened the lid, will buy water blue flower card face up, with the chip side down, according to the direction of the arrow parallel card, and a one-time push. The liquid crystal display meter input data (purchase water amount), water meter valve opens, a minute back card, cover cover operation is completed. If the water meter has heard the buzzing sound, prompts the user has insufficient amount of water, should immediately purchase water: if has water, should be enough water card operation according to the above procedures the water meter, the valve is open, the user should immediately purchase water.
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
Q:Water meter display, replace the battery after water, why not start after the card water meter?.
Card insertion method: in front of the user's card holder, insert the guide slot in the direction of the arrow, observe the LCD screen, and make sure the LCD screen is correct before you can pull out the card. Note: when the card is not finished, it is forbidden to draw the IC card, otherwise it may damage the IC card, and the data in the IC card may not be stored in the water meter, and it may cause the loss of the purchasing water in the IC card. If the card is wrong, try the card again. Make sure the card is inserted and not inserted.
