LMF Laminar Master Flow - Flow Measuring System

The Laminar Master Flow System, LMF for short, automates the dynamic and precise measurement of volume and mass flows of air and gases. Tests and processes can be carried out fully automatically combined with electronic pressure or flow control.

 

Different types of the LMF can be provided with different housings, starting from a panel-mounted instrument up to a 19" slide-in module, also obtainable as splash-proof (IP54). Modularity in the mechanical structure and in the sensor technology of the measuring system as well as in the flexibly configurable evaluation software guarantees the adaptation to different test and measuring problems.

  • Evaluation of 2 measuring sections at the same time

Measuring with a LFE – there is no easier and quicker way!

The Laminar Flow Element (LFE) stands out from all other flow meters by the combination of a fast responding behaviour and a wide measuring range. The reasons therefor are the linear characteristic curve of the LFE as well as the advantages of the volume flow measurement compared with the mass flow measurement.

Precise air and gas flow measurement with fast control!
