Monitor for continuous pressure ratio between two regions - contains temp. sensors before and after heater in connecting line

摘要

The arrangement contains an anemometer which measures the air leakage rate from the higher pressure region to the lower pressure region via a connecting line. The flow direction is measured using two sensors mounted in the line before and after an electrical heating body. The temp. difference between the sensor positions is used as a measure of the speed and flow direction. USE/ADVANTAGE - For measuring pressure difference en-between regions with different air quality requirements. .owa Air flows resulting from very low pressure differences can be measured.
