Inherent to its construction, a thermal mass flow meter or controller
for gases is sensitive to contamination. To increase the MTBF (Mean Time
Between Failure) it is important to make sure that the gas entering the
instrument is clean. The IN-LINE Filter Assembly, screwed into the inlet
of the instrument, provides this service. It contains a 316L sintered metal
filter cartridge that is suitable for general purpose filtration and can
be cleaned with a suitable solvent. If the gas contains a large particulate
content, we advise the use of a pre-filter.
