A combined ultrasonic flow meter and binary vapour mixture analyzer for the ATLAS silicon tracker
Original language description
The instrument has been developed in two geometries following extensive computational fluid dynamics studies of various mechanical layouts. A version with an axial sound path has been used with binary gas flows up to 230 l.min(-1), while a version with asound path angled at 45 degrees to the gas flow direction has been developed for use in gas flows up to 20000 l.min(-1). The instrument with the axial geometry has demonstrated a flow resolution of <= 1 % of full scale for flows up to 230 l.min(-1) anda mixture resolution of 3.10(-3) for C3F8/C2F6 molar mixtures with similar to 20 %C2F6. Higher mixture precision is possible in mixtures of gases with widely-differing molecular weight (mw): a sensitivity of < 5.10(-5) to traces of C3F8 in nitrogen (mw difference 160) has been seen in a long duration (> 1yr) continuous study.
