molbox1+ Flow Terminal
0.125 % of reading—lowest uncer-
tainty for gas flow calibration.
• Allows coverage of flow range
from less than 1 sccm to over
5000 slm with a single user
interface and transportable
system
• Real-time flow measurements
makes adjusting analog flow
devices fast and easy
• Perform fully-automated flow
calibrations using molbox
terminal with COMPASS for
Flow software
• Updated design
molboc-L Laminar Flow
Element
Laminar flow elements for flow
from 1 sccm to 100 slm.
• Traceable to primary gravimet-
ric mass flow measurements
• Multiple gases supported
• Useable with existing molbox1+
and molbox RFM mass flow ter-
minals and COMPASS software
• Integrated filter to protect
against contamination
• Integral gas temperature
conditioning and measurement
• No moving parts that cause
pressure/flow fluctuations or
threaten reliability
molbloc-S Sonic Nozzle
Flow Element
Sonic nozzle based molblocs for
gas flow up to 5,000 slm.
• Covers ranges up to 5,000 slm
in N2 and air
• Multiple gases supported
• Useable with molbox1+, or
existing molbox1 and molbox
RFM mass flow terminals and
COMPASS software
• Proven critical flow ven-
turi (sonic) nozzle operating
principle traceable to primary
gravimetric flow measurements
molbox RFM Reference Flow
Monitor
Compact terminal for making mass
flow measurements using molbloc-
L and molbloc-S flow elements.
• Economical alternative to
molbox1+ terminal
• ± 0.5 % of reading uncertainty
• Covers the flow range of
1 sccm to 100 slm with
molbloc-L, and up to 5,000 slm
with molbloc-S
• 5141/5142/5144 kits feature
molbox RFM, molbloc-L and
other hardware for a complete
calibration system
• No moving parts that cause
pressure/flow fluctuations or
threaten reliability
molstic Mounting Systems
Used to conveniently mount and
protect molbloc elements, connect
to units under test and provide
flow and pressure control.
molstic-L used for molboc-L
mass flow elements.
• Quick connector input
• 2 micron (0.5 micron for low
flow) filter to protect the
downstream components
• Adjustable regulator protects
the molbox transducers
molstic-S used for molbloc-S
mass flow elements.
• Available in 1/2 inch or
1/4 inch system plumbing sizes
• Integrated flow shut-off/
metering valves
Gas Flow Automation
Accessories
MFC-CB™ Control Box
Stand-alone unit for setting/read-
ing analog mass flow
controllers (MFCs) and mass
flow meters (MFMs).
• Set and read 0 to 5 V or 4 to
20 mA on two (2) channels
• Complete front panel local
control and remote operation
via RS-232 and IEEE-488
interfaces
MFC Switchbox
™
Supplies power and switches
between up to five MFCs or MFMs
on one molbox1+ or MFC-CB
channel.
• Duplicates MFC channel
without switching cables
