    1 Safety Instructions 1.1 Correct usage • Prowirl 77 is only to be used for measuring the volumentric flowrate of saturated steam, superheated steam, gases and liquids. If the process pressure and temperature are constant, then Prowirl 77 can also indicate the flowrate in units of mass, energy or corrected volume.

    A vortex flowmeter requires a fully developed flow profile as a prerequisite for measuring volume accurately. The following points must therefore be noted when mounting the Prowirl 77 in the pipeline. Pipe inner diameter When ordering, ensure that the nominal diameter and pipe schedule (DIN/ANSI/JIS) are correct, since calibration of the flowmeter and therefore the achieveable accuracy of the measuring point are dependent on these specifications.
