Turbine water meters are generally a better choice for which flow condition?

Turbine water meters are specifically designed for measuring flow rates efficiently in conditions that involve higher flow levels. These meters utilize a rotor that spins in response to the water flow, with the rotational speed correlating to the volume of water passing through. The mechanism of operation is most effective in moderate to high flow scenarios, where the turbine can achieve stable and accurate readings without being affected by fluctuations associated with lower flows.

High flow conditions provide sufficient velocity for the turbine to function accurately; at low flows, the meter may struggle to register movement accurately due to insufficient force to cause the rotor to spin properly. Therefore, turbine meters are typically not the best choice for very low flows. When evaluating the meter's performance and efficiency, it becomes clear that it excels in very high flows, making it the preferred option for those specific conditions.
