Volume flow calculation according to: V = k · √Δp
with:
• V = Volume flow in m3/h or cfm
• k = flow factor, adjustment range: 1...10,000
• Δp = differential pressure in Pa or InH20
Calculation up to: 999,999 m3/h (587.999 cfm)
Maximum volume flow (Vmax):
Measuring range: 200 Pa, k=10.000
Vmax = 141.421 m3/h; (83.155 cfm)
Measuring range: 1000 Pa, k=10.000
Vmax = 316.228 m3/h; (185.942 cfm)
Measuring range: 6000 Pa, k=10.000
Vmax = 774.597 m3/h; (37.188 cfm)
