Water meter, how to choose the best and effective one?

November 2, 2021

Although, the water meter came up with the idea of ​​basically doing what its name indicates, measuring the amount of water that will be distributed either to a user or even to a farm. This was done clearly thinking of charging for such service and also not wasting said water.

Thanks to all the changes that have been made to it since its invention in ancient Rome, this device has been improving and its measurement is considered to be very accurate.

Next we will explain everything you need to know about this wonderful machine.

How do water meters work?

The operation of the water meter does not have much science, it is a mechanical and relatively easy process. First, the water is transported with a hole where a turbine is located , said turbine is expelled when the water passes through it. Likewise, each of the turns made by the water is recorded by a module that is in charge of counting the number of turns and converting it into milliliters, liters and cubic meters .

Parts of a water meter

It could be said that a water meter has 3 essential parts , and within these parts there are some other parts that would be the mechanism that will allow the machine to perform its work optimally. Let’s see what those three parts are:

  • Recorder / chamber of record. This piece is basically the one that we will see first, as it is located in the upper part of the water meter. Within this part we will find: The file (which recognizes the cubic meters) and the hands (registers the liters and milliliters). On the other hand, in the recorder we will find the typical information that each machine brings with it, such as its serial number, type of capacity, etc.
  • Reduction train. Going down a little we will find the reduction train, which joins the recording chamber with the rest of the measurement elements. This is where magnets and gears are located, which are what allow the water to register (by moving the numbers and the hands of the counter).
  • Measurement elements. Finally we have this piece inside the machine and it is through it that the water passes. The measuring element is made up of the blades and when the water passes through this element, the gears move and thus the water can be recorded in the file.

How to know if the water meter is working well?

Remember that the parts of the water meter are constantly moving, therefore, after many years of being used, the meter could begin to have certain failures, some that we noticed and others that we may not be aware of. Even factors such as the same water that passes through the meter or even the sun, can damage the meter.

The most recommended thing and that we can do ourselves to verify that everything is fine with our meter, is basically to put the water meter to work but while we are there with a very good eye, thus observing if the camera sensors do the registration correctly. For example, you can open a drinking point and without closing it you allow the water to run while you make your observations. By doing that, we can see if any of the pieces move strangely or make sounds that they shouldn’t.

Another test that you can easily do is add to the meter an amount of water that you are aware of (1 liter, for example) and then verify that the meter has done its calculations correctly, that is, that the milliliter sensor has given a whole turn (compared to our example). If that return does not occur, then the meter must be damaged.

Can I fix the water meter?

Honestly, it is not convenient to fix the water meter on our own, and it is not because it is difficult but we must remember that said meter is used in order to collect money, so if we touch it they could believe that we did it to benefit ourselves ; it really is better to avoid problems.

In this sense, the ideal would be to contact the company that provides us with the water meter service and tell them about our problem so that they can put into practice any technical test that is necessary.

How to calculate my water consumption?

Carrying out this is really simple, basically what we will do is follow a formula for which we must know what our current reading is and the previous one recorded by the water meter; for example the previous reading we can easily have it on our water bill. Now, the mentioned formula would be:

Consumption = Current reading – Previous reading

There are also certain general calculations that indicate the approximate water consumption of a person.

For example, certain studies have shown that a person would need 20 to 50 liters of water daily to fully cover each of their needs, including water for cleaning, drinking, bathing, etc.

On the other hand, if we are talking about a family of 4 people then the monthly water consumption varies between 11 to 14 cubic meters . Let us always bear in mind that this is an average figure , as that will vary greatly according to the habits that each family has.


Water meter care

Keeping the meter well cared for is essential to avoid future problems, especially referring to external cleaning, which is where we can contribute. To keep your water meter very clean and therefore careful, follow the following tips:

  • Always keep the registration box closed .
  • Keep the meter area clean, remove any debris or leaves it may have.
  • Clean the outside of the meter from time to time and very gently.

Regarding the latter, you can also choose to ask the same company to perform the cleaning when necessary, as many offer this service and it is safer to leave the meter in the hands of professionals.

It is important that you pay attention to your meter, as this service is necessary at home and it is best to always keep it in optimal conditions.
