What are the benefits of testing a mechanical cold water flowmeter?

Testing mechanical cold water meters is one of the essential tasks of departments belonging to many different product quality control fields. The verification of measuring instruments, specifically cold water meters, aims to ensure the reliability and accuracy of the measuring instruments and is a necessary condition to ensure the observance of the provisions of the law on measurement. practical and effective service for production, business and scientific research activities of the industry, the basis of benefits for consumers as well as the reputation of the product.

Cold water meter is a device associated with the daily needs of all people. Every day we only know how to use water from the operation of the watch and look at the parameters displayed on it, but few of us know if the watch has been tested correctly or not? Why are they tested? And when will it be tested…?

Check the cold water meter, structure and working principle of the meter:

Water meter is a device widely used in water supply and drainage industry, there are usually two main types: mechanical water flow meter and electromagnetic water flow meter. These two types of flow meters have different structures and operating principles:

General principle:

In a mechanical water meter, there is a mechanism that uses the flow mechanism to create a chain of motion that is transmitted to the shaft gear to make the clock jumper to indicate the number of water or the amount of water used.

General structure:

The meter body is made of plastic, cast iron, copper or stainless steel depending on the purpose of use, the two meter heads can have different connection types such as threaded connection and flange connection where the pipe is connected. plumbing.

The display dial is the part to observe the number, the flow of water flowing through the watch. Depending on the principle of the number mechanism, the display dial has different display forms.

Rotary wheel: The part used to sense the flow and transmit the flow of water. They are usually made of heat-resistant and high-pressure materials. For mechanical wastewater meters, the impeller is replaced by a paddle to recognize and transmit the movement of water. Because the load water system contains a lot of garbage and impurities, it is easy to jam the propeller.

Numeric shaft: This is a movement-like mechanism that captures the movement of the propeller to display on the watch dial. The shaft mechanism is calculated and installed so that the meter sets the highest accuracy according to each type of water meter

Mechanical cold water meter

The operation of the water meter is very simple, it is a chain of links on the device, when the customer uses water, the thrust makes the wheel rotate and transmits the movement to the shaft by mechanical gears, the counter part is separated from the fan. Rotate according to the water flow, then the number shaft will act to rotate the hands on the display dial and jump the number to indicate the water flow and water consumption will be displayed above correctly.

Check mechanical cold water meter in any case?

As we all know,  testing the mechanical cold water meter  is a previous job of the measuring unit, testing product quality and then providing it to consumers, but some situations force us to contact them. Immediately contact the technical department to verify:

At some point you find that the meter is too high while you use water not much, this problem you notice through the cost of paying your monthly water bill.

When using water, you discover that the operation of the water meter is irregular as always such as: The clock is still working while you are not using water or running too fast... then we should immediately report it to the agency for inspection. clock back.

In case you feel that you are not using water but the clock hands are still running continuously, it may be the cause of water leakage from water-using appliances in your home or pipes. You should first lock the meter valve, then check the equipment or water pipes, if you find nothing suspicious, you should immediately report it to the inspection unit from the water supply company for handling. timely.

After testing the mechanical cold water meter, the construction unit will try on the meter 2 lead wires, 1 strand of the testing unit is pressed after the equipment is qualified and the 2nd thread is the key. angle pressed by the water company after the meter has been installed in the correct position, the purpose is to prevent water fraud. When you discover one of the lead wires is broken, you should immediately notify the company to check the watch equipment.

Above are some knowledge sharing from the  mechanical cold water meter inspection that  has contributed to the understanding for each user, so that we can promptly handle all situations from this water meter device.
