Separation limit

Separation limit

The separation limit (also ) is the flow rate in a water meter that represents the limit between the lower and the upper load range. ${\displaystyle Q_{trenn}}$ ${\displaystyle Q_{2}}$

The calibration error limit or traffic error limit for flows below the separation limit ( to ) is greater than the error limits in the upper load range to . (e.g. +/- 5% and +/- 2%) ${\displaystyle Q_{min}}$ ${\displaystyle Q_{trenn}}$ ${\displaystyle Q_{trenn}}$ ${\displaystyle Q_{max}}$

With flows in the area of ​​the separation limit, the transition from laminar to turbulent flow usually takes place.
