Which types of water meters are most commonly used in the industry?

The most common types of water meters used in the industry are positive displacement meters and velocity meters.

Positive displacement meters work by measuring the actual volume of water that passes through the meter. These meters operate by trapping water in a chamber, which then moves a dial or counter based on the volume of water that enters. They are highly accurate at low flow rates and are especially suitable for residential and commercial applications where precise measurement is essential.

Velocity meters, on the other hand, measure the water flow rate based on the velocity of the water. As water flows through these meters, it drives a turbine or similar device that correlates flow velocity to volume. This type of meter is often used in larger commercial and industrial applications because they can handle higher flow rates effectively.

In contrast, while digital, analog, magnetic, ultrasonic, and mechanical meters can also be found in the industry, they are not as widely adopted or as conventional as positive displacement and velocity meters. Each of these other types typically serves more specialized roles or specific conditions, hence they are not as universally used.
