Which type of meter is most commonly used for residential customers?

The positive displacement meter is the most commonly used type of water meter for residential customers due to its reliability, accuracy, and ease of use. This type of meter works by directly measuring the volume of water flowing through it by using mechanical components that displace a specific volume of water for each rotation of the internal measuring mechanism.

These meters are advantageous for residential applications because they effectively register low flow rates, which is common in household usage, and provide accurate readings over time. They also require minimal maintenance, making them ideal for residential settings where users expect consistent performance without frequent servicing.

While other types of meters, such as compound meters and rotary meters, are more suited for commercial or industrial applications because of their capabilities to measure larger flow rates or handle varying flow conditions, they are not typically needed for the steady and lower volume of water consumption seen in residential environments. Ultrasonic meters, although they offer modern features, are not as commonly deployed in residential areas due to higher costs and the specific technology required for installation.
