Product overview: molbloc-L Laminar Flow Element

Features at a glance

  • Useable with existing molbox1+ and molbox RFM mass flow terminals and COMPASS software
  • Integrated filter to protect against contamination
  • Integral gas temperature conditioning and measurement
  • Continuous, real-time reading
  • Can be fully automated
  • No moving parts

molbloc-L Ranges
molblocs sizes are designated by a number relative to their nominal flow impedance. The nominal impedance results in nominal flow ranges when flowing nitrogen gas with 250 kPa absolute (36 psia) upstream pressure and 50 kPa (7.5 psid) differential pressure across the molbloc. In practice, the molbloc flow range may be quite different from the nominal flow range. The difference comes from differences in density and viscosity between gases and from different molbloc operating pressure calibration options.

1 Precision: Combined linearity, hysteresis, repeatability.
2 Stability: Maximum change in zero and span over specified time period for typical molbox1+ and molbloc used under typical conditions. As stability can only be predicted, stability for a specific molbloc and molbox1+ should be established from experience.
3 Measurement uncertainty (accuracy): Maximum deviation of the molbox1+ flow indication from the true value of the flow through the molbloc including precision, stability and Fluke calibration standard measurement uncertainty.
