conditions: Water at 20°C
Air at 20°C, 1.013 bar abs.
The conversion to other media or operating data (pressure, temperature, density, viscosity) is carried out
by means of the KROHNE calculation procedure KroVaCal on the basis of the VDE /VDI Guideline 3513.
The specified flow values amount to 100% values of the measuring range.
The turn-down range amounts to 10 : 1
