Class accuracy
Class of external mechanical conditions
The limits of permissible relative error in the ranges of flow rate
of volumetric flow at a temperature of (20±2) °C:
Upon release from production and after repairs:
in the range of flows from Qt ≤ Q ≤ Qmax
in the range of flows from Qmin ≤ Q < Qt
During operation:
in the range of flows from Qt ≤ Q ≤ Qmax
in the range of flows from Qmin ≤ Q < Qt
Sensitivity threshold, max, m³/h
