The benefits of using smart IC card water meters and installation precautions

Abstract: The benefits of using smart IC card water meters and information on installation precautions are provided by excellent flowmeter and flowmeter manufacturers. Advantages of using smart IC card water meters and installation precautions When users use smart electronic cards, they can go to the tap water supply department or sales station to pay for a certain amount of water according to their needs. The above departments will pre-order the user on the computer sales system. water. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the benefits of using smart IC card water meters and the details of the installation precautions. Advantages of using smart IC card water meters and installation precautions When users use smart electronic cards, they can go to the tap water supply department or sales station to pay for a certain amount of water according to their needs. The above departments will pre-order the user on the computer sales system. The water quantity is written into the smart IC card, the user goes back to the house and inserts the card into the smart meter, the micro-power identifier in the meter recognizes the correct password, and reads the pre-purchased water volume of the smart IC card into the memory in the meter. (ix) The control valve circuit issues an order, the control valve opens automatically, and the user starts to use water. When the user uses water, the metering sensing circuit sends the user's water consumption to the controller's microelectronic processor to subtract the user's consumption. When the user's pre-purchased water is used up, the controller will issue an instruction to close the valve and use The corpse must buy water again with the card before continuing to use it. The water meter itself mainly completes the following: 1. Input the new water level value to the storage unit of the water meter: the user inserts the IC card with the newly purchased water level value into the water meter. At the same time, clear the IC card and write encrypted information. 2. Automatic cumulative water consumption: including cumulative water consumption, monthly water consumption and available water consumption, etc., and display it when needed. 3. Automatic alarm function: When the available water in the water meter is less than a certain limit, the indicator light on the water meter will flash continuously to remind the user to purchase water in time. 4. Automatic water cut-off and recovery function: When the available water in a water farmer is zero, and no new water value has been input, the water meter will automatically cut off the valve switch and prohibit users from using water. When Sichuan production enters a new water level value again, the water meter resumes water supply in vain. (1) The smart water meter replaces the traditional water meter, and uses the IC card to realize prepayment and realize the“Pay first, then use water”, The ideal management mode of card settlement, fundamentally eliminate the phenomenon of default, late payment and missed payment of water bills, so that the water companies should pay the bills in time. (2) Establish the computer information management network system of the water company to realize the scientific management of the water supply, water users and the water company; establish a sound financial accounting management to make the daily work and management of the water company streamlined, automated and scientific, Improve the service quality and competitiveness of water companies. (3) Reduce the labor intensity of staff, eliminate/reduce cash transactions, reduce human errors and prevent the occurrence of corruption cases. (4) Provide a convenient auditing and query function to facilitate a comprehensive and timely understanding of the situation and provide a basis for decision-making. IC card water meter system is composed of IC card water meter, general IC card and computer charging management network, the core of which is IC card water meter. Construction and installation points of the water meter 1) The water meter should be installed in a place that is convenient for maintenance and reading, free from exposure to sunlight, freezing, pollution and mechanical damage. 2) The front end of the screw-wing water meter should have a straight pipe of 8 to 10 times the nominal diameter of the water meter, and there should be a straight pipe of not less than 300mm before and after other types of water meters. 3) The rotary-wing water meter and the vertical screw-wing water meter should be installed horizontally; the horizontal screw-wing and volumetric water meters can be installed horizontally, inclined or vertically according to the actual situation; when installed vertically, the water flow direction must be from bottom to top. 4) For the water supply system that integrates life, production and fire protection, if there is only one inlet pipe, a bypass pipe should be installed around the water meter. 5) Maintenance valves should be installed before and after the water meter and on the bypass pipe, and drainage devices should be installed on the water meter and the valve behind the meter. In order to reduce the loss of water head and ensure the straight flow of water flow in the pipe in front of the meter, the gate valve should be used for the maintenance valve in front of the meter. For household water meters in residential buildings, the maintenance valve behind the meter and the special drainage device may not be provided. 6) Water meter wells should be protected from flooding and rainwater. 7) The direction of the water meter should be consistent with its type. 8) When the water meter may reverse, affect the measurement and damage the water meter, a check valve should be set behind the water meter. 9) The installation requirements of the hot and cold water meters are basically the same except for the different working temperatures. The maximum operating temperature of the hot water meter is 110°C. If the hot water meter is installed in front of the boiler or heat exchanger, in order to prevent backflow, a check valve should be installed behind the water meter. 10) There are two ways to install the remote water meter: the remote water meter that only plays the role of outdoor meter reading is relatively simple to install, as long as the water meter output system is connected to the data display device (repeater) installed outdoors; Another way is to connect all remote water meters of the whole building or the whole community to the community management department through repeaters and network controllers, and conduct unified management through terminal equipment. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
