THERMAL MASS FLOW METERS
Sage Thermal Mass Flow Meters are designed for high
performance mass flow measurement of flow rate and
consumption of gases such as natural gas, air, oxy-
gen, digester gas, landfill gas, biogas, gas mixes, flare
gas, nitrogen, carbon dioxide, oxygen and hydrogen.
Sage Metering has distinguished itself by offering a
higher standard – our mass flow meter output is un -
affected by even large process temperature variations,
and our digital electronics is impervious to external
analog noise. Fast response, high resolution, and
ultra sensitivity are features that are at the heart of
every Sage Thermal Mass Flow Meter.
All Sage meters, depending on product style, can be
reconfigured in the field (contact Sage for details
concerning software and related accessories). In addi-
tion, all meters have a convenient in-situ field diag-
nostic procedure that verifies that the original factory
calibration hasn’t drifted, shifted, or changed. This
“Sensor Func tionality and Zero Self Check” also veri-
fies that the sensor is free from contamination, even
without inspection. All Sage Flow Meters are offered
in the Integral Style or Remote Style (with lead-
length compensation up to 1000 feet) with explosion
proof Junction Box with your choice of Probe or
Flow Body depending on your pipe size.
HOW DOES THERMAL MASS FLOW
MEASUREMENT BENEFIT YOU?
• Direct Mass Flow—No need for separate tempera-
ture or pressure transmitters
• High Accuracy and Repeatability—Precision meas-
urement and optimal control of your process
• Turn down of up to 100 to 1 and resolution as
much as 1000 to 1
• Low-End Sensitivity—Detects leaks, and measures
as low as 5 SFPM!
• Negligible Pressure Drop—Will not impede the
flow nor waste energy
• No Moving Parts—Eliminates costly bearing replace -
ments, and prevents undetected accuracy shifts
• Dirt Insensitive—Provides sustained performance
• Low cost of ownership
• Ease of Installation and Convenient Mounting
Hardware
Features and Benefits
The innovative Sage design features an easy-to-use
menuing system, a mass flow, total and tempera-
ture display, and 4-button key pad to integrate the
functions of flow measurement with your specific
needs. You will have the flexibility to use the local
display/keypad (if enclosure removed), or a laptop,
to change configurations or to conduct basic diag-
nostics, in cluding a calibration self-check, with a
simple routine using the keypad. At any time you
can use the convenient menuing system to change
full scale values, digitally filter the flow signal,
change decimal points, set Low Flow cutoffs, check
diagnostics, or reconfigure an insertion meter for
a different pipe size.
