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:Why should the water meter be horizontally installed?
Experts say, many users in order to save money or limited installation position, the water meter import and export pipe length is not enough. The correct installation is 15 mm caliber water meter, upstream of at least 150 mm downstream straight pipe, there should be at least 75 mm straight, otherwise it will because of the flow of "full of twists and turns and affect the measurement accuracy of water meter. In addition, the tap water, such as mixed air, excessive impurities and dirt from the pipe wall, will affect the accuracy of water meter measurement
Q:Why did the water meter suddenly stop IC?
The phenomenon of money off valve is the remaining money in the card list, less than the warning valve, but the card table valve automatically closes. There are many reasons for this phenomenon. First of all, it is necessary to exclude whether due to pipeline reasons, such as jitter or strong magnetic attack table, resulting in automatic shutdown of the meter. There is also a card board of your house, the chip is damaged by damp, need to replace a circuit board module, I have been a water meter for many years, you have seen such a lot of examples
Q:Water leakage or water meter bad at home, regardless of how to do?
If the owners Water Leakage inside their own Water Leakage, or Water Leakage upstairs, the owners should repair or maintenance of the owners upstairsThe classification of this situation:(a) if the warranty period, the developer should be responsible for maintenance;(two) if the warranty period has passed, the owner shall maintain it by himself.
Q:How can I make the meter and meter go slow?
Do you want to see your first type water meter, now generally tap water companies are rarely installed high precision meter (accuracy >2L/H), is a common type of water meter (accuracy >10L/H), as long as you drop (a faucet is dripping intermittent 2L/H; continuous drop of water is 4L/H; 200L/H is fully open) can not exceed 10L/H but, small water measurement is not accurate, but is less than normal.
Q:How to buy a water meter
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.
Q:Does the card type water meter support only "one card one meter"?
Home card, card activation table and card are only brush off the table, so the owners do not have to worry about the wrong card brush
Q:How can I see the water meter stealing water?
The first test of water seal is intact, we know that the meter dial is the use of copper dial and case connected in the dial and case are respectively provided with a hole, used to wear seal wire, pressure seal ball. If it is found that the seals and seal wire breakage, prove the water table has demolished the suspect.
Q:What's wrong with a water meter with a flange connection?
Is the two pipe, pipe fittings or equipment, first fixed on a flange, two flanges, plus flange pad, bolted together, completed the connection. Some pipe fittings and equipment have their own flange, but also belong to flange connection.
Q:What is the working principle of the code type pre paid water meter?
Automatic argument: the controller is rejected and the number of errors recorded when the error data is entered. If 8 consecutive input errors, the control system is fully closed, and only the operator can unlock to recover.
