- High accuracy: Especially in low-flow and very low-flow conditions, its accuracy is significantly higher than that of other water meters. This is because even if the water flow is very slow, as long as it continues to flow, it can be divided into small units for measurement. Being able to measure tiny flows, such as dripping water, is a significant advantage.
- is based on volume division, and they are relatively less affected by changes in flow velocity (especially within the range of common flow rates).
- Low starting flow rate: The minimum flow rate required to initiate measurement is very low, making it sensitive to even the smallest flows.
- Wide range ratio: Positive displacement water meters usually have a wide range ratio, which means they can maintain high measurement accuracy within a relatively large range of flow rate changes.
