Sentrol BB-1GS Pressure-Sensitive Barrier Bar

[Music] uh hi this is pete singer with my conductor digest and i'm talking to muhammad saleem who is the cto of brooks instrument hello muhammad how are you good pete how are you great so um you've recently introduced a differential pressure sensor based mfc and i wondered if you could explain a little bit about the the brooks approach yeah absolutely so let me let me talk about how the pressure-based mfcs operate in general so that you get a good idea what we are trying to do here so the pressure-based mfc's in general use a defined flow restriction to create a pressure drop in response to gas flow that is measured and and utilize measurements of temperature pressure upstream pressure downstream in computational flow so by knowing the fluid properties and the geometries of the flow restriction classic fluid mechanics principles can be used to determine the mass flow rate so the convent
