摘要：

The performance of a constant-temperature hot-wire anemometer for respiratory-gas-flow measurement has bee investigated. It is shown that the anemometer satisfies common demands with respect to accuracy, response time and to insensitivity to humidity and temperature variations. A calibration method is suggested that permits correction for variation of the flowmeter signal caused by changes of the gas composition. Finally, a procedure for linearisation of the flowmeter signal as a function of flow rate is presented. © 1979 IFMBE.
