Burkert: Type 8743 & Type 8744 Thermal Mass Flow Controllers and Meters With Capillary Sensor for Aggressive Gases and Gas Mixtures
Type 8743 and Type 8744 serve both as a mass flow controller (MFC) with a proportional valve and a mass flow meter (MFM). Both types rely on a media-separated capillary sensor made of 316L/1.4404 stainless steel with a nominal flow rate (QNom) ranging from 0.01 lN/min to 100 lN/min (nitrogen). Capillary sensors use a non-contact measuring principle. The sensor components themselves have no direct contact with the gas. This makes Type 8743 and Type 8744 particularly chemically resistant to many aggressive gases.
