SAGE PRIME™ THERMAL MASS FLOW METER
FOR GASES
Sage Prime is the top selling meter in our Product Line. The Sage
Prime Thermal Mass Flow Meter features a bright, high contrast,
photo-emissive OLED display of Flow Rate, Total and Temper ature
in a robust, yet lightweight, dual-compartment industrial enclosure.
The flow rate is also displayed graphically in a horizontal bar graph
format. The rear compartment is completely separated from the
electronics, and has large, easy-to-access, well marked terminals, for
ease of customer wiring (see photo below). It is powered by 24 VDC
(12 VDC optional, or 115/230 VAC). The power dissipation is under
2.5 watts (e.g. under 100 ma at 24 VDC).
The Sage Prime Flow Meter is offered in Integral or Remote Style
(which has lead-length compensation up to 1000 feet as well as an
Explosion Proof Junction Box). Specify any standard probe length
or flow body size. It has a 4-20 ma output as well as a Pulsed Output
of Totalized Flow (solid state transistor drive). In addition, Sage Prime
supports full Modbus® compliant RS485 RTU communi cations (IEEE
32 Bit Floating Point).
Sage Prime is CE approved, and CSA and UL approved for
Hazardous Service 2 (see Approvals tab on the website).
CONTINUOUS DIAGNOSTICS & FIELD
CONFIGURABILITY
Sage Prime has continuous diagnostics. The raw calibration milli-
watts (mw) is always displayed in the upper left hand corner of the
meter's display. At any time, you can check this reading at a "no flow"
condition, and compare the reading to the original re ported "zero
flow" value noted on the last few lines of your meter's Certificate of
Con formance or the flow meter's data tag. This in-situ diagnostic pro -
cedure not only checks the sensor performance and the "live zero"
calibration point, but it also verifies that the sensor is clean. It essen-
tially provides a means to validate that the meter is oper ating prop-
erly, verifies that there is no shift or drift, and eliminates the need for
annual fac tory calibrations. This simple field diagnostic procedure,
in addition, verifies that the sensor is free from
contamination, even without inspection.
Although Sage Prime is fully configured
upon shipment, for the pipe and process
con ditions requested, there are three
strategies if changes are needed: Sage
DONGLE; the Sage ADDRESSER software
program; or the Sage ADDRESSER advanced pro-
gram. Contact Sage for details.

MAJOR BENEFITS OF THERMAL MASS FLOW METERS
Direct Mass Flow – No need for separate temperature or pressure
transmitters
High Accuracy and Repeatability – Precision measurement and
extraordinary repeatability
Turndown of 100 to 1 and resolution as much as 1000 to 1
Low-End Sensitivity – Measures as low as 5 SFPM (e.g., 1 SCFM
in a 6" pipe)
Negligible Pressure Drop – Will not impede the flow or waste energy
No Moving Parts – Eliminates costly bearing replacements, and
prevents undetected accuracy shifts
Dirt Insensitive – Provides sustained performance
Low cost-of-ownership
Ease of installation and convenient mounting hardware
SPECIFIC BENEFITS OF THE SAGE PRIME
High contrast photo-emissive OLED display with numerical Flow
Rate, Total and Temperature, as well as Graphical Flow Indicator
Photocell activated Screen Saver to extend display life
Calibration milliwatts (mw) is continuously displayed, providing for
ongoing diagnostics, and in-situ calibration check
Modbus® compliant RS485 RTU communications
Isolated 4-20 ma output
Rugged, user-friendly packaging with easy terminal access
Option for Solar Energy use (12VDC models)
Low power dissipation, under 2.5 Watts (e.g. under 100 ma at 24 VDC)
Powerful state-of-the-art microprocessor technology for high per-
formance mass flow measurement and low cost-of-ownership
Proprietary digital sensor drive circuit provides enhanced signal
stability and unaffected by process temperature & pressure changes
Remote Style has Lead-Length Compensation. Allows remote elec-
tronics up to 1000 feet from probe; Explosion Proof Junction Box has
no circuitry, just terminals
Field reconfigurability via Sage ADDRESSER or Sage DONGLE
Flow conditioning built into In-Line flow meters (1/2" and up)
Captive Flow Conditioners for Insertion Meter applications, if required
1 Note, a built-in photocell continuously monitors the ambient light, and adjusts the display brightness for
optimum long-term life, and also senses motion which automatically switches display from Screen Saver
mode to Normal mode
2 Only available with 24VDC powered meters
