Flow specifications
Pneumatic flow
Total flow sensing
Parameter
Range
Flush flow
35 to 75 l/min
Flow range
Minimum O2 flow 50 ml/min
O2
•
0.05 to 0.95 l/min
•
1 to 15 l/min
N2O
•
0.05 to 0.95 l/min
•
1 to 10 l/min
Note: The Link-25 system sets the nominal O2 flow to 25%
of the total of O2 and N2O flow.
Air
•
0.05 to 0.95 l/min
•
1 to 15 l/min
Accuracy
•
At 20
°
C with gas supply pressures at 345 kPa (50 psi)
and an outlet pressure of 101.3 kPa (absolute) (14.7
psi) flowmeter accuracy agrees with VDE 3513 Part 3,
Accuracy Class 2.5 or better.
•
Different breathing circuit pressures, barometric
pressures or temperatures change the accuracy. With
some conditions, these changes can be larger than
the tolerances.
Flow Range
O2
0, 0.05 to 15.0 l/min
Air
0, 0.05 to 15.0 l/min
N2O
0, 0.05 to 10.0 l/min
Total
0 to 40.0 l/min
Accuracy
•
Greater of ± 25 ml/min or ± 6% of measured value at 20-25
°
C
with gas supply pressures at 480.5 kPa (69.7 psi) and an
outlet pressure of 101.3 kPa (absolute) (14.7 psi).
•
Different breathing circuit pressures, barometric pressures or
temperatures change the accuracy. With some conditions,
these changes can be larger than the tolerances.
