Turbine meters are devices used to measure the flow rate of liquids and gases. They operate by using a rotor that spins as the fluid passes through the meter. The speed of the rotor is directly proportional to the flow rate, allowing for accurate measurements. These meters are commonly used in various industries, including oil and gas, water treatment, and chemical processing. Their design makes them suitable for high-flow applications, and they can provide real-time data, which is essential for monitoring and controlling processes efficiently.
