Thermal Mass Flow Meter - Kurz 454 FTB
In this report flow meter Kurz 454 FTB (serial no. FD21544A) with firmware version 1.04 has been evaluated. The flow meter can be used to measure and monitor air flow in ventilation systems and in other type of air/gas ducts. It indicates flow rate or velocity on its internal display as well as giving an analogue (4-20 mA) signal output. There are also digital alarm output signals. During most tests the flow meter was installed in a small test duct, exposing only the sensor (the tip of the insertion rod) to the flowing air. By recalculation of the reference flow rate and reference velocity, both measured velocity and normalised volume flow rate from the instrument could be verified.
