Volume flow measuring

D-FL100
Differential pressure flow measuring system for dry emissions

This system operates according to the differential pressure principle. The probe has two seperate chambers, between which the flow builds up a differential pressure.
Taking account of the other flow parameters such as absolute pressure and temperature, the volume flow can be converted from operating to standard conditions with the help of the D-FL100-10 microprocessor evaluation unit.

D-FL200
Ultra-sonic flow measuring system for wet and aggressive smoke emissions

The D-FL200 measuring system works according to the accoustic pulse differential method. Ultrasonic transducers mutually send and receive short impulses with and against the gas flow which affects their transit time. The volume flow is calculated from the difference of transit times.
