summary:
This water meter is a new product developed by our company based on the original ordinary prepaid water meter. It is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water usage and transmit and settle water usage data. This product connects the prepaid water meters of each household through RS485. Users can swipe their cards through public card readers and query water information. It has a series of advantages, such as convenient use, advanced technology, excellent performance, reasonable structure, accurate measurement, stability and reliability. It is mainly applicable to the water supply measurement and charge management of urban water supply departments, property communities, enterprises and institutions, and industrial and mining residential communities.
This type of water meter has RS485 networking, GPRS remote control, and centralized card swiping function, which greatly facilitates property management and is an ideal product for gradually realizing intelligent property management. The performance of the main product meets all the requirements of GB/T778-2007 and CJ/T133-2012 standards.
characteristic:
It has a prepaid function to buy water first and use it later After the water in the water meter is used up, the valve will automatically close. Users need to purchase water from the management department through an RF card or through the internet before opening the valve to use water, and both methods can be used simultaneously.
Networking function: The property management department can achieve functions such as recharging users, retrieving information from tables, and remotely forcing on/off valves through the 485 communication network, monitoring the water usage information of each user. Management personnel can recharge and supply water to users without leaving their homes.
Centralized card swiping and display function: It can be equipped with an external card swiping device that is separate from the water meter. Multiple water meters (preferably less than 50) can be connected to two external card swiping devices through a 485 cable. Different users can share one card swiping device to swipe the card and transfer the value charged in the card to the water meter When the water meter is installed in the pipeline well, the external card reader can be placed in a convenient location for users to swipe cards and query information, making it easy for users to operate. The card reader is powered by a separate battery, with low power consumption and a battery life of over 6 years.
GPRS wireless remote control function: The property management department can recharge and supply water to users through GPRS DTU wireless data transmission terminals Valve opening, closing, and other operations.
After the user recharges and purchases water, when swiping the card on the water meter, the LCD screen displays information such as room number, user number (hh), number of water purchases (cs), current water purchase volume, alarm volume (bl), current remaining water volume, card reader number, and storage limit in sequence. When the user swipes the card on the water meter, the LCD screen of the water meter displays information such as current water purchase volume, water meter number, user number, number of water purchases, alarm volume, total water consumption, current remaining water volume, and stored water volume in sequence.
When the property management department needs to inquire about users' water usage information, they can use the property detection card to check the information of a certain household on the card reader. At the same time, the property management department can also force the valve to open or close by controlling the valve card on the card reader or on the water meter.
The product adopts a unique physical sealing design for each part, with excellent sealing effect. The battery compartment door is designed on the front of the water meter, making battery replacement extremely convenient. The water meter has low power consumption and a battery life of over 6 years.
Battery voltage monitoring function: When the built-in battery voltage drops to the critical voltage, the LCD display will display an alarm and the water meter will automatically close the valve to prevent ineffective valve closure due to low battery voltage. After replacing the battery with a new one, the water meter will automatically open the valve to supply water after swiping the user card.
