Arrangement for measuring the mean value of physical quantities of media flowing in a duct

To measure the mean temperature or humidity of air flowing in a duct, a number of sensors (MFA) are arranged over the duct cross-section, which measure both temperature (Xi) or humidity and the velocity of flow (v1). The output signals of the temperature sensors are supplied to a processor which cal...

Zusammenfassung:	To measure the mean temperature or humidity of air flowing in a duct, a number of sensors (MFA) are arranged over the duct cross-section, which measure both temperature (Xi) or humidity and the velocity of flow (v1). The output signals of the temperature sensors are supplied to a processor which calculates the mean value in accordance with the following formula: Main field of application of the invention is air conditioning systems.
