Which type of water meter uses the flow of water to spin a turbine?

The type of water meter that uses the flow of water to spin a turbine is the propeller meter. These meters operate based on the principle that the flow of water moves a turbine, which is typically located within the meter housing. As water flows through the meter, it causes the turbine blades to spin. The rate of rotation is directly proportional to the velocity of the water flowing through the meter. This rotation is then translated into a measurable volume of water that has passed through the meter, allowing for accurate flow measurement.

Propeller meters are particularly effective in measuring larger volumes of water and are commonly used in applications where high flow rates are expected. The design ensures that they are sensitive and capable of providing real-time data on water usage. Other types of meters, like piston, magnetic, and Venturi meters, operate on different principles, making them suitable for varying conditions and purposes but not utilizing a spinning turbine to measure flow.
