Water meters

When choosing a water meter, you first need to check what size and capacity you require. Most single-family homes use a meter in size Q3 2.5 or Q3 4, while larger buildings may need bigger dimensions. The meter must handle the property’s expected water flow without causing pressure drop.

You also need to consider which type of meter to use. In small residential installations, mechanical single-jet or multi-jet meters are the most common. In more advanced systems, or where high accuracy is required, ultrasonic meters are used because they have no moving parts and offer a longer service life. Always choose a meter that is MID-approved and accepted by your local utility, since many municipalities specify which types and brands are allowed.

The municipality usually decides how the meter installation must be arranged. The meter should be mounted in a meter bracket with shut-off valves before and after the meter. It must be installed in a frost-free location and be easy to access for reading or replacement. In some cases, a water meter chamber is required if the meter cannot be installed indoors.

If you want remote reading, you need to choose a meter with pulse output, radio communication or another type of digital interface. This is becoming more common and helps users track consumption and detect leaks.

In summary: check the correct meter size, use a type approved by your municipality, choose between mechanical or ultrasonic technology, and make sure the installation can be done frost-free with proper valves and a meter bracket.
