What is the main purpose of a water meter?

The main purpose of a water meter is to measure water consumption for billing purposes. Water meters are installed in residential and commercial buildings to track the volume of water used over a specific period. This measurement is crucial for water utility companies as it helps determine the charges that customers owe based on their actual usage. By providing accurate data on water consumption, meters play an essential role in water management and conservation efforts. They ensure that customers are billed fairly according to the amount of water they use, making them an important tool in the water supply system.

While measuring water pressure, controlling flow rate, or indicating water temperature are important aspects of plumbing systems, these functions do not align with the primary role of a water meter, which is solely focused on tracking water usage for billing.
