Intelligent water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption, transfer water data and settle transactions. Compared with traditional water meters, which generally only have the functions of flow collection and mechanical pointer to display water consumption, it is a great progress. In addition to recording and electronic display of water consumption, the intelligent water meter can also control water consumption according to the agreement.
The water consumption can be recorded and displayed electronically; The water consumption can be controlled according to the agreement, and the water charge calculation of step water price can be completed automatically. At the same time, the function of water data storage can be carried out; Data transmission and transaction settlement are carried out through IC card, which has the characteristics of convenient transaction, accurate calculation and bank settlement.
The correct diameter of water meter shall be selected for water meter installation; Install horizontally, with the surface facing upward, and the arrow direction on the watch case is the same as the direction of water flow. The installation position shall avoid exposure, flooding, freezing and pollution, and facilitate disassembly and meter reading. When installing a new pipeline, be sure to wash the sand, gravel, hemp and other sundries in the pipeline before installing a water meter, so as not to cause water meter failure.
Valves shall be installed upstream and downstream of the water meter, and all valves shall be opened when in use; Necessary straight pipe sections or their equivalent rectifiers shall be installed upstream and downstream of the water meter. The length of the upstream straight pipe section shall not be less than 10d and the length of the downstream straight pipe section shall not be less than 5D (D is the nominal diameter of the water meter). For the eddy current phenomenon caused by elbow or centrifugal pump, a rectifier must be installed in front of the straight pipe section; When installing the water meter, it should be noted that the water outlet of the downstream pipeline of the water meter is more than 0.5m higher than the water meter, so that the measurement of the waterproof meter is incorrect due to insufficient water flow in the pipeline.
