Rate Since thermal flow sensors are sensitive to changes in air density and air velocity all thermal flowmeters indicate flow rates with reference to a set of standard conditions For TSI instruments standard conditions are defined as 21 1 C 70 F and 101 3 kPa 14 7 psia Other manufacturers may use different values Standard flow rate is the flow rate the air would be moving if the temperature and pressure were at standard conditions It is usually the most useful measure of airflow because it defines the heat carrying capacity of the air Volumetric flow rate is the true volume flow of the gas exiting the flowmeter In some instances volumetric flow rate rather than standard flow rate may be of interest To display volumetric flow rate the Model 4140 4143 will multiply the standard flow measurement by the following density correction factor VolumetricFlow StandardFiow SE ES 273 15 21 11 Pm Where Tin Gas temperature measured in flow tube in units of degrees Celsius Pim Absolute pressure measured in flow tube in units of kPa To demonstrate the difference in output consider the following Measured flow displays 10 Std L min at 15C and 117kPa The volumetric flow as calculated by the Model 4140 4143 would be as follows 8 478L min VolumetricFlow 1 o 273 15 15 101 3 273 15 21 11 117 17 UK Tel 44 149 4459200 E mail tsiuk tsi com Website www tsiinc co uk France Tel 33 491 952190
