Abstract
1 Scope This International Standard specifies a method for the determination in a closed conduit of the volume rate of flow of a regular flow:
a) of a fluid of substantially constant density or corresponding to a Mach number not exceeding 0,25;
b) with substantially uniform stagnation temperature across the measuring cross-section;
c) running full in the conduit;
d) under steady flow conditions.
In particular, it deals with the technology and maintenance of Pitot static tubes , with the calculation of local velocities from measured differential pressures and with the computation of the flow rate by velocity integration.
