How does a smart water meter work, and how does it work?

Smart water meters. It is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption, transmit water data and settle transactions. Compared with the traditional water meter, which generally only has the function of flow collection and mechanical pointer display of water consumption, it is a great improvement.

In addition to recording and electronically displaying water consumption, the smart water meter can also control the water consumption according to the agreement, automatically complete the calculation of the water fee of the stepped water price, and can store the water data at the same time.

The water consumption can be recorded and electronically displayed, the water consumption can be controlled according to the agreement, and the water fee calculation of the stepped water price can be automatically completed, and the function of water data storage can be carried out at the same time.

1. The working principle of smart water meters.

By installing a sensing element at a certain position of the reading dial pointer or gear set of the water meter, the mechanical reading of the raw water meter is converted into electrical signal data, and then collected, transmitted and stored, and controlled automatically or manually according to the requirements of the settlement transaction method.

2. Working methods.

Insert the IC card containing the amount into the IC card reader in the water meter, and after the microcomputer module identifies and ** the amount, the valve is opened, and the user can use water normally. When the user uses water, the water quantity collection device begins to collect the water consumption, and converts it into the required electronic signal to feed the microcomputer module for measurement, and displays it on the LCD display module.

When the user's water consumption amount drops to a certain value, the microcomputer module will give an audible alarm, prompting the user to pay the card to purchase water. If the amount of water consumption is exceeded, the microcomputer module will automatically close the electronic control valve and cut off the water supply. Until the user inserts the IC card that has been paid, and starts to open the valve again for water supply.

The smart water meter applies high-tech electronic and information transmission technology to the manufacture of water meters, which has changed the traditional meter reading and settlement methods in China to a considerable extent, and improved the level of tap water charging and metering in China, which is a technological progress in tap water metering and charging; Its popularization and application has realized the "buy water first, then use water" and centralized meter reading management, updated the concept of payment of water users, reduced the phenomenon of arrears of water bills, household meter reading, etc., and reduced the manpower and material resources of meter reading of water supply management departments; The water fee can be advanced in advance, which reduces the later operation personnel, improves the management efficiency and the management level of the water department; And the anti-theft performance is better than that of ordinary water meters, and it can fully realize the functions of "prepayment", "stepped water price" and "hoarding water".

There are many types of smart water meters, and the right water meter can be selected according to different needs and places of installation and use. And now the waterworks, and even some enterprises, will use electromagnetic water meters. The electromagnetic water meter can be used in combination with the leakage control system, which is convenient and fast, and can find and deal with problems more quickly, and implement real-time monitoring and management.

The leakage control system independently developed by Qingteng Environment is a high-tech product developed and used in combination with its own electromagnetic water meter products, leading the trend of the times.

Water meter principle - rotor water meter.

The working principle of the rotor type single-beam water meter is that the water flow tangentially impacts the impeller from the case inlet to make it rotate, and then continuously records the number of revolutions of the impeller through the gear reduction mechanism, so as to record the cumulative flow through the water meter.

The working principle of the rotor multi-beam water meter is basically the same as that of the single-beam water meter, which is through the distribution of the impeller box, and the multi-beam water flow is tangentially impacted from the water inlet of the impeller box, so that the water flow has an axial impact on the impeller.

It is balanced, reduces the wear of the impeller supporting part, and reduces the influence of water meter installation and scaling on the water meter error from the structure, and the overall performance is significantly higher than that of the single beam water meter.

Water meter principle - rotary piston water meter.

The rotary piston water meter uses the pressure difference between the two ends of the water meter metering room (water inlet and water outlet), and the water flow entering the water inlet pushes the piston to rotate and squeezes the water in the metering room to the water outlet. As the piston rotates, the volume of the low-pressure end (water inlet) gradually decreases, and the volume of the high-pressure end (water inlet) increases. Every 1 rotation of the piston, the water of a metering chamber volume is squeezed out of the water outlet, and the fork is rotated by the piston shaft for 1 rotation to record the water consumption.

The piston records the water consumption of a metering chamber volume every 1 week, which can be calculated theoretically, and the material friction coefficient of the parts in the metering cavity of the water meter is small, and the geometric dimension accuracy is high, so the metering accuracy of the water meter is very high, and it can reach the level of ISO4064C and D, which is very beneficial to the water charge. The disadvantage is that the water quality requirements are relatively high. The movement of the piston along the wall of the metering chamber is a rolling and sliding process, and the gap between the piston and the metering chamber is only, so impurities and fine sand will seriously affect the metering performance and service life of the water meter.

Water Meter Principle - Smart Water Meter.

At present, the smart water meter manufactured in China can be divided into two categories: prepaid water meter and remote water meter, and its common feature is that the sensor that measures the water flow still adopts the ordinary water meter, and the mechanical reading of the original water meter is converted into electrical signal data by installing a sensing element at a certain position of the reading plate pointer or gear group of the water meter, and then collects, transmits and stores it, and controls it automatically or manually according to the requirements of the settlement transaction mode. Because their base meters are all speed water meters, so according to the principle of water meters classification, they also belong to the speed water meter category, but in the reading mode, indication mechanism and other aspects have been improved, increase prepaid, remote reading and other automatic meter reading system functions, and the metering mechanism, transmission mode or mechanical, the accuracy of the water meter.

Accuracy) grade is the same as ordinary mechanical water meter, it is grade.

<><6. Then this water meter is now using 0+ tons of water.

Installing a smart water meter at home can bring convenience to daily life, but you must also know the working principle of the smart water meter, otherwise once there is a problem, you don't know how to repair it, and it will be troublesome. So how does the smart water meter work, and how to maintain the smart water meter, do you know it? Now let's take a look.

1. What is the working principle of the intelligent water source chronology?

The smart water meter is to install a sensor device inside the reading plate, so that the mechanical reading of the water meter can be converted into an electrical signal, and then the smart water meter will further collect, transmit, and store the data, so as to display the water consumption data according to the needs of the occupants.

2. How to maintain the smart water meter.

1. When the smart water meter has been used for a long time, it will be contaminated with too much dust on its surface, if it is not cleaned in time, it is easy to let the dust accumulate more and more, and it is very troublesome to clean it after the dust is very strong. In serious cases, it may also directly lead to the error of the meter degree.

2. In the process of using smart water meters, regular maintenance is also indispensable. When the surface of the water meter is stained with acid and alkali stains, it needs to be wiped clean in time, otherwise the acid and alkali substances are very likely to cause the water meter to be corroded. Of course, the water meter also needs to be protected from moisture, otherwise there will be reading errors, so once there is a water stain, it must be wiped dry.

3. Smart water meters are installed on water pipes, so whether it is for the good of smart water meters or water pipes, you can't put heavy objects on the water meters, otherwise it will cause damage. If there is an adverse reaction to the smart water meter, do not disassemble and assemble it at will, but contact the after-sales personnel to be responsible.

About how the smart water meter works, and how to maintain the smart water meter, I will introduce it here, do you understand it? The use of smart water meters is not difficult, but it is necessary to know the details of use to ensure that there will be no problems in the future.
