D-FL 100 Flow measuring system

D-FL 100 Flow measuring system

D-FL 100 Flowmeter is a suitability-tested and certified impact pressure system to measure velocity and volume flow of dry flue gas or process gas in pipes or ducts.

The D-FL 100 measuring system operates according to the differential pressure principle. The probe has two separate chambers between which the flow builds up a differential pressure. The evaluation unit determines the gas velocity and the volume flow (norm conditions or standard conditions) from the differential pressure, taking into account gas temperature and gas pressure.


Features D-FL 100 Flowmeter:

  • Reliable measurement of the gas velocity even at high temperatures
  • Calculation of volume flow at standard conditions
  • Automatic zero check option
  • Certified, cost effective measuring system
  • Versions with or without counter-support and for point measurement
  • Extremely low maintenance, maintenance interval 6 months
  • Convenient operation via remote access with web interface

Applications D-FL 100 Flowmeter :

  • Volume flow measurement at high temperatures
  • Volume flow measurement at high pressure
  • Plants with large or small flue cross-sections
