What should I do when the water meter is turned upside down?
The inversion of water meters can be divided into two aspects: human 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 water meter, the 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, the manual bar, the reverse is man-made, and a few soil method is also 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. Take a look at the external forces, the water meter upside down, the macro should be a kind of water meter rotation, so the cause of the water meter rotation is also applicable to water reversing. Well, how to solve the inverted water meter? Is the first flip meter, you can buy some water in the industry known as anti flip artifact known as the heat shrinkable soft diaphragm, only need to install the meter when it will be set in the pipe above, with hot water or hair dryer blowing, will be good fit to take over, if you want to split the table will flip to break the heat shrinkable flexible membrane, which is a kind of effective method. The second is simply the problem of water table rotation, although the national standard says the water meter rotation within a certain limit is allowed, but the inverted water meter is completely uncontrollable. At present, only control to avoid the occurrence of water meter rotation, for example, you can install the exhaust valve and check valve, so as to maximize the water meter rotation.
The reverse of the water meter is because there is air in the water pipe. You can open all the taps and drain the air out.
