Friends, Germany will choose Beijing intelligent smart meter, eliminating all the sadness! Huairou cumbersome procedures smart meter charges, meter reading people need to knock on the door, entered the room, meter reading, writing payment receipts; If the owners do not often at home, we should ask the owners own meter reading, there will be a lot of problems and shortcomings in these areas were. Due to various reasons the owners can not pay on time. Mechanical meter has been unable to adapt to the development and social progress of the times, the need for a more humane and more convenient water measurement tools. The Baoshan smart meter is a good solution to these problems, without manual meter reading into the house, the owners are not required readings, property owners can go to recharge card companies or banks idle at any time, you can purchase a one-time or a few months In the water. Huairou smart meter Description: Key Features: 1 Table B-class intelligent valve one movement, with clear reading, measurement accuracy, appearance, health and safety features. 2 high-quality double-reed structure, a variety of work, which can effectively prevent measurement errors due to fibrillation, brought backwater, while the external magnetic field can be detected, to prevent human Pirates of the water. 3 users a table and a card, a card table, smart defense with a password decryption, copy protection. 4 LCD cumulative amount of water, enough of this water, the remaining water. 5 arbitrarily set water restrictions: less than water limit automatically close the valve without water, prompts the user to purchase water, insert the card user to restore the water supply until the remaining water is reduced to zero. 6 meter reverse installation, the remaining amount of water consumed in the table as usual, to prevent cheating. 7 meter when there is no electricity, table data can be stored for 10 years is not lost. 8 SMT technology, small size, low power consumption, high reliability main features: a truly integrated structure of the flow meter ball valve, without fear of leakage of joints; 2, the use of low-power intelligent control ball valve, ball valve switch, reliable, positioning accuracy, small pressure loss; 3, the calculator unit may be mounted on the base table, may be easily observed in other parts of the installation according to the needs; 4, with the customer replaceable alkaline batteries, lithium batteries that the internal life; 5 , integrator temperature measurement resolution of 0.01 ℃; a table and a card contactless quarter meter and control system (single circuit) Description of the quarter-contact water meter designed using non-contact RF smart t5557 as a data transmission medium, should has the following features: 1, automatic sampling measurement functions quarter meter large size lcd controller with LCD display, can automatically collect metering information machinery quarter meter can be set per one ton or measured once every 10 tons. 2, to purchase water feature will have to purchase water for the purchase of water card into the controller, the controller displays the purchase of water first, then the controller will share this water and the remaining water to accumulate inside the display on lcd controller currently available continue to use the remaining water, then displays the cumulative use of water controller. 3, the alarm function when the remaining amount of water used to water the default alarm 1:00, the controller uses optical alarm signals simultaneously lit lcd, not off valve without water. Each light alarm signals to a metering pulse, flashing alarm light tube five times, LED lights no longer than 100 ms, 1 second delay off time, cancel the alarm function after inserting the card to purchase water. When the remaining water to the preset alarm with water 2:00, lit lcd controller with alarm while off valves, water alarm 2 is less than 0, after inserting the card to purchase water meter controller opens the valve a quarter of the remaining water to 0 to restore the water does not off valve directly into overdraft status. If the alarm is set to 0 2 water, then turn off the valve, the user inserts the card to purchase water valve can be opened into overdraft status. 4, a quarter meter off valve shutoff function must have the overdraft feature, when the remaining water after use, do not close the valve a quarter meter automatically enters the overdraft status, when the remaining water to equal the record overdraft limit, the controller will shut down again a quarter meter valves, then the user only payment options again to open water valve. 5, the query function (1) check the balance will purchase water card into the controller, lcd display shows the user's current and cumulative amount of water remaining water on the windows. (2) query quarter meter information into the controller card with a query, you can query the current state of the controller to use, and make one complete valve controller switching action, lcd display window in order to display the user's current remaining water, the cumulative use water, water consumption last month, the current calendar, the current clock. 6, the meter reading function: You can use the card to a quarter meter meter controller month freeze data copied back to the water, for analysis. 7, back in the water feature with a special card into the water to return back the water table, put the controller back to the table to write the remaining water withdrawal of water cards, and the remaining water table is cleared, close the valve to stop water users. Here Huairou smart meter range of application: contact piping systems, residential road in charge of billing, afforestation of agricultural irrigation wells, etc.. Metering module uses reed sampling method, in contact header section to complete the installation of two reed sampling work, valves and motors are law-abiding place switch installed in the control box. Control box installed main circuit board, a fully enclosed structure, a multi-card card selection, when a multi-card near the control box, touch switches or reed in place (using the core there is a multi-card), then Controller main cpu start a multi-card reader to read and write circuit cards, data exchange, the data exchange is completed, the display on lcd display significantly after the end of the latest data, round off the display, has been in a dormant state to conserve power . A multi-card contactless quarter meter and control system (single circuit) advantages a modular design, maintenance services more convenient biggest feature is the modular design of the product, that the master valve controllers, valves are completely modules, even in the internal master, we have a modular design. The greatest advantage of the modular design is extremely easy to service, which is essential for contactless smart meter --- a quarter of a quarter because of contactless smart meter is not allowed to easily split the table! From a practical perspective, a quarter of our contactless smart meter base table, the valve is completely reliable, very low probability problems. Failure is often caused by a battery, master, and now this design ensures that no one can replace the master plumber or battery, greatly simplifying maintenance service volume quartile contactless ic card meter! 2, enhanced sealing performance, long battery, circuit board and run master interface part of the underwater signal circuit boards have taken special sealing process to ensure a stable and reliable work underwater for a long time. 3, the switch valve time is short, and does not produce water hammer due to the pilot valve using the principles of design and for the Chinese water quality has been improved, as compared with ball valve, gate valve, butterfly valve, the switching time is shorter and does not produce water hammer. 4, low power consumption and free from scale effects of a battery can be driven by the pressure due to the switching valve in the water pipes, and valve switching is no friction, and thus will not use for a long time because of the scale and cause the valve to produce off valve resistance increases. A lithium battery can be used for more than three years. 5, an increase in the return water feature with a special card into the water to return back the water table, put the controller back to the table to write the remaining water withdrawal of water cards, and the remaining water table is cleared, close the valve to stop users water. Third, the main parameters of a base table double reed sampling 1m3 (or ten times, a hundred times) send a pulse.
