Benefits of Using a Smart IC Card Water Meter and Installation Precautions
Benefits of Using a Smart IC Card Water Meter and Installation Precautions When the user uses the smart electronic card, they go to the water supply department or the sales station to pay a certain amount of water according to the needs of the user. The above department writes the user's pre-purchased water amount into the smart IC card on the computer sales system, and the user returns. The house inserts the card into the smart meter, the micro power identifier in the watch identifies the correct password, and the pre-purchased water of the smart IC card is read into the memory in the watch, the controller (9) controls the valve circuit and the control valve opens automatically. The user starts to use water. When the user uses water, the metering sensor circuit sends the amount of water used by the user to the controller's microelectronic processor minus the user's usage. When the user's pre-purchased water is used up, the controller will issue an instruction and the valve will close. The corpse must re-hold the card to purchase water before continuing to use it. STORAGE FROM 10 TO 200m³
Feiyya cement and lime silos are the equipped version of the traditional monolithic and telescopic silos. They have a diameter of 2.2. 2.4.2.6.3.0.3.2 and 3.6 m, can have a storage capacity from 10 to 200 m³ and are suitable for storing and dosing cement, lime, ash, sand and similar materials. Sized to optimize transport costs, pre-cabled and pre-assembled, Feiyya silos are an economical solution suitable for a fixed installation, or for those who do not require specialized machinery for mobile sites such as horizontal silos.
Cement and lime silos are equipped with a gravimetric electronic weighing system with decreasing load cells which allow: (1) the unloading of the material by deduction weighing,( 1996031,2) the setting of automatic unloading programs,( 1996032,3) the automatic management of the vibrator,( 1996033,4) the control of the purchased quantities,( 1996034,5) the control of the remaining quantities.
Cement and lime silos are equipped with an adjustable timer discharge system which allows: (1) the discharge of the material in volumetric mode,( 1996035,2) the setting of the timer scale in seconds, minutes or hours,( 1996036,3) the additional management of the discharges in fully manual start/stop mode.

The water meter itself mainly completes the following:
1. Enter the new water value into the storage unit of the water meter: the user inserts the newly purchased IC card into the water meter. After the water meter judges the legality of the card, it saves the stored water value of the IC card into the water meter. The memory unit also clears the IC card and writes encrypted information.
2. Automatically accumulate water consumption: Includes information such as accumulated water consumption, water consumption of the current month, and available water, and displays it when needed.
3. Automatic alarm function: When the available water in the water meter is less than a certain limit, the indicator on the water meter will flash continuously to remind the user to purchase water in time.
4. Automatic water cut and recovery function: When the amount of available water in a water farmer is zero, a new water level value has not yet been entered, and the water meter will automatically cut off the valve switch and prohibit users from using water. When Kawasaki again entered a new water value, the water meter resumed water supply.
(1) Intelligent water meter replaces traditional water meter, uses IC card to realize pre-payment, realizes the ideal management mode of “pay first and then use water†and card settlement, and fundamentally eliminates the phenomenon of overpayment, late payment, and missed payment of water fee. Water companies should be paid in time for use.
(2) Establish a water company's computer information management network system to realize the scientific management of water supply, tap water users, and water companies; establish a sound financial accounting management to make the water company's daily work and management process, automation, and scientific. Improve the water company's service quality and competitiveness.
(3) Reducing the labor intensity of staff, eliminating/reducing cash transactions, reducing human error and eliminating corruption cases.
(4) Providing a convenient nuclear query function to facilitate comprehensive and timely understanding of the situation and provide a basis for decision-making. The IC card water meter system is composed of an IC card water meter, a general-purpose IC card and a computer charge management network, and its core is an IC card water meter.
Water meter construction, installation points
1) The water meter should be installed in a place convenient for inspection and reading, free from exposure, freezing, pollution and mechanical damage.
2) The front of the screw-type water meter should have a straight pipe with a nominal diameter of 8 to 10 times the water meter. Before and after the other types of water meter, there should be a straight pipe of not less than 300mm.
3) Rotor-type water meters and vertical-wing type water meters should be installed horizontally; horizontal-wing type and volume-type water meters can be installed horizontally, inclinedly or vertically depending on actual conditions; when installed vertically, the direction of water flow must be from bottom to top.
4) For a water supply system that integrates life, production, and fire fighting, if there is only one inlet pipe, a bypass pipe should be installed around the water meter.
5) The maintenance valve shall be installed on the front and rear of the water meter and on the bypass pipe, and the water discharge device shall be installed on the water meter and the rear valve. In order to reduce the head loss and ensure the straight flow of the water flow in the tube in front of the watch, the gate valve should be adopted for the pre-maintenance valve. The household water meter in the house may not have a post-watch maintenance valve and a dedicated drain device.
6) The water meter well should prevent flooding and rain.
7) The direction of the water meter should be consistent with its type.
8) When the water meter may be reversed, affecting the metering and damage to the water meter, a check valve shall be provided behind the meter.
9) The installation requirements for hot and cold water tables are basically the same except that the operating temperature is different. 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, a check valve should be installed behind the water meter to prevent backflow.
10) There are two methods for installing the remote water meter: the installation of the remote water meter, which only plays the role of outdoor meter reading, is relatively simple, as long as the water meter output system is connected to a data display device (relay) installed outdoors; Another way is to connect all the remote water meters of the whole building or the entire community to the community management department through the repeater and the network controller, and perform unified management through terminal equipment.
