Calculation example for gas
• Sensor: Promass O, DN 80
• Gas: Air with a density of 60.3 kg/m³ (at 20 °C and 50 bar)
• Measuring range (liquid):180
000 kg/h
• x = 130 kg/m³ (for Promass O, DN 80)
Maximum possible full scale value:

: x = 180
000 kg/h · 60.3 kg/m³ : 130 kg/m³ = 83

Recommended measuring range
"Flow limit" section (→ 105)
Operable flow range
Over 1000 : 1.
Flow rates above the preset full scale value are not overridden by the electronics unit, with
the result that the totalizer values are registered correctly.
