To establish a metering of water consumption in housing and communal services, meters with a pulse output are used, which can conduct automatic monitoring. The counters connect to an external repeater of data transmitting information to the server of the management company through the selected channel. A water meter with a pulse output provides a specific procedure for reading information.
Principle of operation
The principle of operation of such a counter is not complicated: it consists of a mechanical part with a rotating impeller and a magnetic coupling. The basis of the coupling is a simple magnet and a sealed contact (gergon), which is closed by the influence of a magnetic field.
Pulse water meters are beneficial for management companies as metering devices, which allow saving water use. They allow you to economically calculate the consumed resources and simplify the process of calculating the used water. Each volume of water in such water meters is used very economically.
Types and types of water meters
The ordinary water meter and the universal Betar SGV-15 meter do not differ that much. This is a device for metering hot and cold water, which is installed in any home. It can operate in the temperature range from +5 to +100 ° C. The device consists of a housing, an impeller and nozzles. There is also a counting mechanism. The SGV-15 counter is a modification of the SHV-15, the current name is Betar SGV-15. This model is designed to work at home in certain ranges. For cold water, the upper limit is 40 ° C. The volume of water that is consumed in the device is equal to 1.5 cubic meters per hour. The weight of the counter is small, it is equal to 0.5 kg.
The Betar meter has its advantages: the main one is saving water. "Betar" is inexpensive and lasts almost six months without warranty repair. When using the meter, you only need to know the monthly water consumption, which we can see on the meter’s dial, and water tariffs. In general, for a person this amounts to 6 meters in a cube, and for a tariff in accordance with the new rules. As we already wrote, the Betar counter consists of an impeller and a counting mechanism. The counting mechanism counts the number of rotations - the more pressure, the more the impeller spins and the amount of water spent is displayed. A water meter with a pulse output works in the same mode: information from the meter is read in an electronic device, which is convenient in operation. In general, water meters of this type work for energy and water conservation.
Application. Which counter is better
For practical use in rural and other areas, water meters manufactured by Betar are more preferable. Depending on the conditions of water use, savings, everyone chooses a meter at their discretion, depending on their financial capabilities. A cold water meter with pulse output or another type of pulse meter is also used in water heating systems, which are connected with a low-power pump. They can be used in household, bath rooms, where the required water metering is required. If for household needs water is taken from the wells, then there are practically no need for water meters. Pulse output meters work perfectly with both cold and hot water.
What to consider
Before buying a water meter, keep in mind the following:
• what water will pass through the meter;
• check hard or contaminated water;
• what is the cost of the meter;
• how much energy is needed to operate the device;
• where the water meter will be installed.
For their capabilities, meters for cold and hot water work the same, but are made of different materials. The pulse counter for hot water works up to 150 ° C, and for cold water the limit is up to 40 ° C. If the water is highly polluted or has a stable hardness, then the meters must be selected of a special type or a dirt filter should be placed on the meter. Dirty water significantly affects the accuracy of the readings, because the speed of rotation of the impeller in the counter slows down. When buying, you should also pay attention to this.
Meter Advantages
The advantage of a water meter with a pulse output can be considered its compact weight, meter dimensions, mandatory design, mechanical simplicity, reliability and operational efficiency. Pulse counters are also used in production where we need the use of water, as well as their direct use as process water in the processing of parts and their subsequent assembly. The meters are mounted on a vertical pipe that feeds and is used as needed, and stored in specially designated places. It must be noted that some parts of the meter may undergo corrosion attack, and therefore they must be coated with a special solution composition that prevents the formation of rust. The mechanical part of the pulse water meter is protected by special devices that provide protection during careless use. The pulse cold water meter and the Betar meter version are a necessary argument in order to save energy and water in our urban and rural water supply systems. They are the best help in resource-saving technologies in home and local-territorial conditions.
Conclusion
Nowadays, the cost of communal housing services has increased significantly, and therefore people began to think about saving the budget, which they saved for the future. Here, pulse meters for hot and cold water can significantly save home and family savings. In rural local areas this is very important and necessary. In urban centralized housing systems, the entire system of water use and economy is supplied in accordance with the law. There, water meters with a pulse output for displaying information are also needed, they help to navigate the system of utility bills.
Thus, water meters for household use are a necessary attribute in residential premises and help to save money.
