Abstract:

Calibration curves of laser control console pressure versus mass flow rate for the four input species H2, SF6, O2 and He were measured for the single and two channel laser control consoles. Several interesting phenomena were observed. The mass flow meter choked unless placed upstream of the flow control orifice and a laminar to turbulent transition occurred in the flow control orifice.
