at full scale and use of the KF flange adapter DN 25
decreasing quadratically with smaller flow rates
approx. 15 mbar at operation without special sieve and at full
scale flow rate.
1) Approximate values are given for applications with air under atmoshperic con-
ditions. The values in brackets indicate the lower limit of the measuring range
for which the measured value accuracy indicated is specified.
2) It is possible to specify any unit which you can transform into a mass or stan-
dard volume flow. For Example 1 ballon/min = 7 l/min - q
