product overview

The LYHY-8 series rechargeable intelligent pure water meter (including contact and non-contact) is a prepaid measuring instrument composed of a rotary piston volumetric base meter with a transmitting device as the measuring base meter, an IC card as the medium, an electronic controller, and an electric ball valve. It adopts a high-performance and high-efficiency RISC structure microcontroller in the circuit, and integrates various control circuits such as clock, LCD driver, alarm driver, pause, wake-up function, etc. of the controller into a dedicated module in a highly integrated manner, making the intelligent pure water meter highly anti-interference, reliable, high-precision, and low-power performance. Its compact structure design and beautiful appearance. This table has the functions of measuring, memorizing, and displaying the drinking water that can be directly consumed through a closed full pipeline. It automatically opens the valve to supply water directly for consumption according to the amount of water purchased by the user. When the water reaches the alarm value or runs out, the valve will automatically close and cut off the water supply, thus achieving the goal of "paying first, then using water". It can also record the operation status of the water meter, display the operation status of the water meter through the system management software through a microcomputer, and implement effective monitoring.

PRODUCT FUNCTION

1. Pre order drinking water quantity: The user card that has already purchased water will be paired with the smart pure water meter and placed near the smart pure water meter. If the remaining amount in the meter is greater than 0, the intelligent pure water meter can open the valve to supply water.

2. Query function: It can query the cumulative water consumption, remaining water consumption, and current purchase water consumption.

3. Measurement and statistics: The device can automatically deduct the user's consumption, deducting 1L for each count, and can correctly accumulate the newly purchased consumption in the card with the remaining consumption in the device. Accurately accumulate consumption figures.

4. Alarm and valve closing: When the remaining water volume is 0.1 m3, the intelligent pure water meter will display an "alarm" prompt and close the valve, reminding the user to purchase water in a timely manner. Then, the user card paired with the intelligent pure water meter can be brought close to the intelligent water meter before the valve can be reopened until the water volume reaches zero, and the intelligent pure water meter will automatically close the valve. The 'alarm' disappears when the re purchased water volume exceeds 0.1m3.

5. Function card recognition: When a legitimate user card or function card approaches the smart pure water meter, the data of the card is read into the meter for normal operation. When illegal or scrapped cards approach the smart pure water meter or other operational errors occur, the smart pure water meter will sound an alarm and display the "card error" character.

6. Anti magnetic function: When a magnet with a magnetic induction intensity of ≤ 0.15T approaches the intelligent pure water meter, the intelligent pure water meter can work normally. When the water meter is artificially damaged by strong magnetism (>0.15T) or other means, the pure water meter will display the characters "stolen" and "closed valve", and the valve will be closed. When the magnetic field leaves, the pure water meter will open the valve to supply water, and the characters "stolen" and "closed valve" will disappear.

7. Anti theft function: The pure water meter adopts a fully sealed installation and is equipped with an anti damage card seal. If it is disassembled without authorization, the card seal of the pure water meter will be damaged.

8. Undervoltage protection function: When the power supply voltage is lower than the set value, the intelligent pure water meter displays the "undervoltage" character and closes the valve within 1 minute. The water meter rechecks the battery. If the voltage has been charged above the set value, the "undervoltage" character disappears, and the valve is opened for water supply after 5 minutes, or a legally paired user card is used to open the valve for water supply.

9. Charging function: When the power supply is under voltage, the pure water meter will close the charging switch, allowing charging. Insert the manufacturer's dedicated charger, and the charging indicator green light will light up. After the power is fully charged, the pure water meter control system disconnects the charging switch and prohibits charging. The charging indicator green light of the charger is off.

Product Features

1. The "Chunchao" brand LYHY-8 series IC card rechargeable intelligent pure water meter has a unique design and is a patent with national appearance application. The design of our company's IC card rechargeable intelligent pure water meter has applied for relevant patents. It uses a 3.6V rechargeable lithium battery imported from Japan, with a long service life (the control circuit uses imported low-power components). It is corrosion-resistant, leak free, and has overcharge, overdischarge, overcurrent, and short-circuit protection functions. Compared with water meters that use ordinary batteries or lithium-ion batteries without charging functions as power sources, it is both environmentally friendly and safe, reduces the cost increase for users due to battery replacement, and also avoids data loss caused by battery replacement.

2. The measuring material adopts high-quality non-toxic engineering plastics with composite wear resistance, which can maintain the reliable performance of this pure water meter, with high measurement accuracy and clear readings.

3. Electric ball valves are driven by metal gears. Compared to the resin materials commonly used by manufacturers, it is more wear-resistant and has a longer service life.

4. Adopting aluminum die-casting, stainless steel, PC and other rotary piston volumetric base meters to provide convenience for users to choose. The selected materials comply with the hygiene standards for drinking water measuring instruments.

5. The shell is made of polycarbonate material imported from Japan. Anti debris smashing, anti glass shattering, with strong impact resistance, anti-aging, corrosion resistance, and durability.

6. The control units of this pure water meter adopt advanced fully sealed technology, which is waterproof, moisture-proof, and has strong anti-interference ability.

Installment and use

1. This table is only applicable to pure water and hot water should not be used. Avoid exposure to sunlight and freezing.

2. This table has high requirements for water quality, with turbidity not exceeding 1 degree. It is not allowed for the water to contain particles and fibrous debris. When installing new pipes, it is necessary to wash away stones, sediment, hemp fibers and other debris inside the pipes before installation to avoid water meter failure.

3. This table allows installation in any position, but it is preferable to install in a horizontal position (with the dial facing upwards). During installation, the direction of the arrow shown on the water meter must be consistent with the direction of water flow in the pipeline.

4. When installing this table, it should be connected to the pipeline through joints. Do not forcefully pull the water meter during disassembly to avoid breaking the case. Valves must be installed in front of the table for maintenance purposes.
