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.
In short, the problem of water table rotation, although the national standard says that 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, such as the installation of exhaust valve and check valve, so as to maximize the water meter to avoid rotation.
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?The first kind of flip chip meter, as manufacturers purchase some water in the industry known as anti flip artifact known as the water heat shrinkable film tamper device, only need to install the meter when it will be set in the pipe above, with hot water or hair dryer blowing, will be a good fit to the tube, if to remove the table must be broken flip heat shrinkable flexible membrane, which is a kind of effective method.
