General Operation:
The Flow Head integrates O2, N2O and Air channels (the N2O and Air channels are optional).
The O2 Air and N2O needle valves gas supply pressure is externally regulated to 200KpaÂ±10Kpa.
Performance:
(Note: Standard flow conditions defined at 20ÂºC,101.3Kpa, (760mmHG))
Flow Tubes
Flow tubes shall be calibrated for discharge into an ambient atmosphere of 101.3kpa at an operating temperature of 20ÂºC.
Each flow tube shall be calibrated toÂ±10% of reading, or better.
Flow tubes must withstand 690kpa internal pressure without breaking.
