Overview

Fluke Cal Molbloc-Ls are laminar flow elements for use with molbox mass flow terminals. The molbloc flow path is the longitudinal, annular gap between a piston and a close fitting cylindrical bore in the molbloc body. Different molbloc ranges are obtained by varying the size of the gap. For high flow ranges (size 1E4 and above), a larger molbloc body with a larger cylindrical bore is used.

Features
- Useable with existing molbox1+ and molbox RFM mass flow terminals
- 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

Major Applications
- Gas Flow calibration
- Calibration of compressed gas Flow meters
