Specification
Flowmeter A cc u r a cy
The accuracy of the flowmeter tubes is ± 2.5% of full scale reading.
Flowmeter construction and d i m e n s i on s
Tubes and floats are matched, and must not be interchanged. Flowmeter tubes have antistatic coatings.
Tubes are length indexed:
Oxygen 260 mm (10.24 inch)
Nitrous oxide 250 mm (9.84 inch)
Air 240 mm (9.45 inch)
Scale length 152 mm (6 inch) minimum

4.5 Auxiliary Gas O u t l e t s
O xy g e n: Two self sealing connections on rear of machine
Air (on machines with Air supply option): Two self sealing connections (mini-Schrader) on rear of machine.
Supply pressure
Pipeline supply: Gas is supplied at pipeline supply pressure (see above)
Cylinder supply: Gas is supplied at reduced pressure from cylinder regulator (see above)
Flow rate
Flow rate for each gas 60 L/mn maxmum
WARNIN
Flow rates greater than 60 L/mn could affect the fresh gas flow to the patent
