What is the characteristic flow of a water meter?
Boundary flow: the flow range is divided into two areas where the flow appears. "High" and "low" the freedom of a district to characterize the maximum permissible error.
Minimum flow: within the maximum allowable error limit, the minimum flow required by the meter is given. It is related to the value of the water meter code.
Commonly used flow: the water meter in the normal working conditions, that is, stable or intermittent flow, the best use of flow.
Overload flow: water meter in a short period of time, and without damage, the maximum use of flow, the value of two times the usual flow.
