THERMAL MASS FLOWMETER

On-line measurement of exhaled NO requires exhalation at a constant flow rate. The TSI thermal mass flowmeter permits direct measurement of the exhalation flowrate using the NOA 280i or the NOA 280 equipped with the flowmeter upgrade kit (Part # AML 01487-01). The flowmeter is installed on the On-Line NO Breath kit and the signal processed by the NOA. Calibration is performed using standard calibration syringes (1-3 L) and the NOAnalysis 3.21 REB program. The flowmeter has a fast response time (4 msec) and low pressure drop. The 25.4 mm OD ISO-taper outlet fits over the Amlurate NO breath kit mouthpiece and a 22 mm OD ISO-tapered inlet fits the NOA bacterial and viral filters. The polycarbonate body is compatible with standard cold sterilization agents. The flowmeter employs two sensors; a platinum film sensor is heated and maintained at a constant temperature to measure flow and a temperature sensor is used to compensate for changes in gas temperature.
