An example of a large-flow water meter is:

The magnetic type of water meter is considered a large-flow water meter because it is designed to measure the flow of water in large pipes with high accuracy and minimal pressure loss. This type of meter uses electromagnetic principles to derive flow rates, which allows for precise readings under various flow conditions. Unlike other types of meters, magnetic meters do not have moving parts that encounter friction or wear, making them ideal for handling large volumes of water over extended periods.

Magnetic meters are particularly useful in industrial and municipal applications where the flow of water can be substantial. They can also handle a variety of water qualities, including those containing solids and other particulates, without compromising measurement accuracy. This versatility and reliability make magnetic meters a preferred choice for large-scale operations, demonstrating their capacity effectively in demanding settings.

Other types of meters, such as displacement, gear, and floater types, are generally more suited for smaller flow rates and may not provide the same level of performance when dealing with large volumes of water.
