Prepaid smart cold and hot water meter

Overview
Water meter modules made from prepaid water meter together with base Meter and housings, can quickly develop prepaid step water meters that meet national standards GB/T778.1 to 3-2007 and industry standard CJ/J133-2007. The module adopts a new type of low-power microcomputer controller, adopts advanced logic encryption technology, implements a table and a card, ensures the user data is safe and reliable, and its billing method can be measured by ladder, which promotes the user to save water. The intelligent water meter produced by this module completely changed the traditional water mode from "water first, pay later" to "pay first, pay later water" mode, which greatly facilitated the work of the community property management department and the water resources management department.

Features
Prepaid function: the user buys water before using it, and owes the fee to close the valve to stop the water.

Step-by-step metering function: you can set up a step-by-step metering method to promote users to save water.

Liquid crystal display function: display the purchase of water, surplus amount, cumulative water consumption, valve status and many other data information.

Tip alarm function: battery underpressure, insufficient available water, strong magnetic interference and other fault information, the module will prompt the alarm.

Data telex function: data remote transcription, so that the management to understand the user's water situation and the status of the table.

Remote valve control function: the manager can remotely control the switch valve of the water meter as needed.

Valve self-maintenance function: valve rotation, timely removal of valve scale, to ensure the flexibility of the valve.

Anti-hoarding function: through the software can flexibly set the lower limit of top-up, to prevent users from hoarding water.

Installation instructions
1. The newly installed pipe must rinse the sand, sediment, hemp and other debris in the pipe before loading the table, so as not to cause water meter failure.
2. Water meter specifications should be appropriate for common flow, can not rely on the pipe caliber to determine the caliber of the water meter. Water meters should not be used in corrosive liquids, and cold water meters do not allow access to hot water.
3. The direction of the arrow on the case must be the same as the direction of the water flow when the water meter is installed, and the horizontal water meter installation must be horizontal. The water flow direction of the vertical water meter must be bottom-up. Water meter installation location should be able to avoid exposure to the sun, and easy to remove and observe the site, cold winter festival should take insulation measures.
4. The water meter must be installed at the inflow end of the boiler with a check valve to prevent hot water and steam from reflowing and damaging the water meter.
5. It is strictly forbidden to hold anything on top of the water meter. Pay attention to moisture,anti-humidity, water droplets are strictly prohibited into the water meter controller damage control system affect the normal use of users.
6. Water meter installation, pay attention to the connection length of the water meter, when the two ends of the line spacing exceeds the length of the water meter connection, should be corrected line spacing, to meet the length of the water meter connection, otherwise the space is too large forced installation will cause the water meter connection thread end break or the fitting joint broken and connection nut damage;
7. For accurate measurement, the tap should be higher than the water meter.
8. Water meters should not be directly connected to the pipe, water meters and pipes should be connected by connecting pipes, sealing washers, connecting nuts, when disassembly, cut not available hard trigger, so as not to twist the case.
9. When installing a water meter with water saving and energy saving, it is necessary to use a special fitting at the ining port to reduce the water meter transition caused by water pressure fluctuations.
10. Since the installation is not carried out in strict accordance with the installation precautions, resulting in damage to the water meter or its accessories, all losses are at the installer's own risk.
11. The network directly selects RVVP 2x2x0.75 or more wires, communication power AC220V power supply.
Maintenance of smart meters
1. After long-term use, debris blockage or part wear and other reasons caused errors, must be repaired and used. Lead-sealed users on water meters shall not be damaged, and water companies or management departments shall be notified of any abnormality.
2. After the card table is installed and used, the operation of the meter and the battery voltage should be checked regularly.
3. After a few years of operation, when the display data is not clear, it may be that the battery is low, the battery should be replaced immediately by a specialist technician.
4. If you find lcd (LCD screen) display garbled or abnormal symbol logo, please contact the water sales department.
5. The meter belongs to the metering device, must be in accordance with the national standards of the smart water meter regular inspection, and at the check time to replace the battery.
Declaration
1. The user shall not remove the lead seal without authorization, otherwise it shall be treated according to the damage.
2. The Company reserves the right to make changes and amendments to this description, subject to change without notice, whichever is the actual product.
Accessories
Equipped with connection nuts, take-over, rubber seals two each.
Important tips
1. About the antifreeze of water meters
The normal working environment temperature of the water meter should be above 0 degrees C, before the onset of winter and cold areas, the use of water meters, management departments must do a good job of water meter anti-freeze work.
Any water meter due to improper installation or use of the receiver nut, pipe rupture, water meter ice, freezing, freezing and other causes of water meter damage, water suspension, leakage and other related losses (such as water leakage soaked floor, furniture, equipment, etc.) caused by water meter management, product suppliers and manufacturers are not responsible.
2. Questions about the inso se as to the mechanical part of the display
For smart water meters with mechanical word wheel display at the same time, if the electronic part is damaged, resulting in the electronic part is not displayed or inconsistent with the mechanical word wheel display value, according to the relevant provisions of the National Measures Law, the calculation of usage shall be based on the mechanical word wheel part of the watch.
3. Questions about negative product numbers
When the product's table balance is 0, if the valve fails to close due to foreign objects stuck and other reasons, the user continues to use water, will continue to normally measure the cumulative water consumption, and the amount of water to walk more on the "residual" display as a negative number. The next time the user buys a water swipe card, the amount of overdraft will be automatically deducted, will not cause cost loss to the charging department. If there is a situation where individual users have not purchased water for a long time or the average water consumption is abnormal, the management department of the smart meter should visit the household in time to check the user's water status and check out the abnormal situation in a timely manner.
The suppliers and manufacturers of smartwatch products shall not be liable for any loss of water caused by the poor inspection and management of the smart meter management department.
