  D-FL 100 Technical data
measuring principle measurement of impact differential pressure at a multi hole probe, calculation of gas velocity and volume flow taking into account cross section of the duct, sample gas temperature, pressure and density
type in situ, measurement cross stack, half duct or single point, probe is in contact with sample gas
system components D-FL 100 S probe
D-FL 100 A adaptor
D-FL 100 UH valve*
D-FL 100 DDM-H differential pressure transmitter
D-FL 100 ADM-H absolute pressure transmitter*
D-XT temperature transmitter*
accessories
measuring range 0 to 40 m/s,
0 - 4...3,000 * 1000 Nm3/h
any range within the measuring range can be assigned to the analog output
resolution 0.1 m/s
expanded uncertainty
EN14181 / EN ISO14956 / EN15267-3		 better than 0.9 m/s at range 0 - 20 m/s,
the accuracy depends on installation, measuring path, flow profile and the accuracy of the reference measurement used for calibration
