The characteristics of prepayment water meter, installation notes, classification, use and disposal of common problems

The traditional “water first, pay after” into “first payment, after the water”, to effectively solve the charge problem. The detailed design process uses the EM78 series single-chip design of specific hardware circuit diagram and software is given..

prepayment water meter

(1) does not need manual meter reading, and is conducive to modern management. With the “one table” one household, the meter number of power supply enterprise management has increased dramatically, the installation of prepayment electric energy meter is used for

Strengthen the modernized management of electric enterprises, improve the service level of a best choice. The use of prepayment electric energy meter also avoid manual meter reading to the inconvenience charges to bring customers, and historical data can prepayment water meter, easy for customers to query.

(2) fully reflects the commodity attribute of water. Prepaid water meter according to the principle of commodity exchange, the first water after the water, completely changed the traditional water charging mode, fully embodies the commodity property of hydraulic. Customers can according to their actual needs to plan to buy water, water, no late fees and because of arrears, adding unnecessary expenses.

(3) to solve the problem of fees. 1, the use of radio frequency card, without any exposed electrode, moisture-proof performance, easy to use.

2, through the double key encryption card, a card a secret.

3, with a card table, or a card table function.

4, with the remaining water is insufficient, prompting the user to buy water.

5, with the battery voltage is too low, to prompt the user to replace the battery.

5, with the battery voltage is too low, to prompt the user to replace the battery.

6, has the data read back, when the user card to the management center for water, can use the card corresponds to the cumulative water consumption in the water meter, battery status, interference frequency read back to the management center.

7, small starting flow, high precision.

8, display function: surplus for the purchase of water, water, with a total content and other parameters can be effectively displayed on the LCD screen, the user can through the user card check table in the surplus water and total water use information.

Installation:

Installation:

1, choose water should be used according to the pipeline flow less than or close to common flow meter is appropriate, not only to determine the water pipe diameter.

2, the installation location to avoid light pollution, drying, freezing, the frozen period, in addition to water pipes wrapped insulation, when not in use the water inlet end of the valve is closed, the outlet valve and open the water tap, can prevent water frost damage.

The meter must be installed level, so that the literal upward.

Installation of piping must be inside the tube gravel, silt, hemp and other debris washed clean after the installation of water meters, so as to avoid the water meter malfunction.

Installation of piping must be inside the tube gravel, silt, hemp and other debris washed clean after the installation of water meters, so as to avoid the water meter malfunction.

In order to measure accurately, the tap should be higher than the water.

The water meter installed on the boiler into such as pipes, should be installed check valve, prevent the return of hot water scalding water.

The water should not be directly connected with the pipeline, water meter and the pipeline should active interfaces (such as pipe joints, connecting screws, over the sealing gasket etc.). The installation of brass body IC card water meter, should not be excessive force caused by pipe and pipe fitting, so as not to damage the water meter.

The meter must be installed in the floor drain and smooth drainage.

The meter must be installed in the floor drain and smooth drainage.

Seven, transportation and storage

1, the water transportation should not be subject to severe shock. Save water meter should be in the original packaging, preservation of the local environmental temperature 0 ℃ -60 ℃, relative humidity below 95%, non corrosive gas in the air.

The water in the warehouse storage, stacking height of not more than 10 box, water meter stack single package put height of not more than 10, not only the water meter packaging open storage.
