Characterization of Thermal Flow Sensors for Air Flow Measurements in Transport Containers

Conference paper
Part of the Lecture Notes in Logistics book series (LNLO)

Abstract

Air flow measurements inside containers for sensitive and perishable products effectively participate in improving transport processes. Results of such measurements allow taking preventive actions to maintain the desired temperature during transport trips. Consequently, we can optimize the quality of transported goods and reduce their losses. Thermal flow sensors are chosen for these measurements. This paper introduces an overall characterization of these sensors to prove their suitability for the intended objective. The characterization covers the air velocity range from 0 to 5 m/s, which is the expected range in the container. Results show that the characteristic curve is linear for the ultra low flow range and the minimum detectable air velocity is ca. 0.4 mm/s.
