Welcome
We are pleased that you have purchased a Sage Metering Mass Flow Meter for your
requirement. We hope that you are satisfied with the performance, operation and
design of our highly precise, NIST traceable Thermal Gas Mass Flow Meter.
Sage Metering is your source for monitoring, measuring and controlling the gas mass
flow in your industrial process, building management system or environmental application. Our high performance, NIST Traceable,Thermal Mass Flow Meters will help
increase productivity, reduce energy costs, maximize product yields, and/ or help reduce
environmental insult. Sage provides high quality In-Line and Insertion Thermal Mass
Flow Meters for a wide variety of industrial, commercial, and environmental monitoring
needs, including carbon credit verification for Greenhouse Gas reduction.
Sage Meters measure mass flow directly — there is no need for ancillary instrumentation
such as temperature or pressure transmitters. Furthermore, our instruments have exceptional signal sensitivity, have no moving parts, require little if any maintenance, have
negligible pressure drop and have a turndown up to 100 to 1, and resolve as much as
1000 to 1. Sage Flow Meters can measure the mass flow rate and consumption of air,
oxygen, natural gas, nitrogen, digester gas, biogas, flare gas, hydrogen, argon, carbon
dioxide and other gases and gas mixes.
Sage Prime is the latest addition to our family of high performance Thermal Mass Flow
Meters. It features a bright graphical display of Flow Rate,Total and Temperature, robust
industrial enclosure, and easy to access power and output terminals. Sage Prime has a
dual-compartment windowed enclosure featuring a very high contrast photo-emissive
OLED display with a new photocell activated Screen Saver. The rear compartment,
which is separated from the electronics, has large, easy to access and well marked terminals, for ease of customer wiring. 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
for the DC version.)
Please let us know if we can assist you in any way with your Sage Meter, or if you
have any questions about its installation, operation, or features. Simply phone us at
866-677-SAGE (7243), or visit our website at www.sagemetering.com to contact a
factory representative in your area. This manual is available on the website under
Knowledge Base section.

1 The Integral Style of Sage Prime Insertion Meters have the Display oriented as shown on page 14.
If an alternate orientation of the display, or enclosure is required (ie. installation into a vertical pipe),
please furnish a sketch or drawing, and specify “ROTATE” on purchase order. However, if it is later
determined that the enclosure needs to be rotated, that procedure can be done in the field. However,
if the display needs to be rotated, then the meter must be sent back to Sage to be modified. Do not
attempt this in the field. An RMA will be required prior to returning the meter (see page 51). The
procedure for rotating the enclosure is as follows: Clamp the enclosure of the Prime in a vise with the
probe pointing up to the ceiling. Then take a 7/8 wrench and turn the probe to the proper orientation. Lock the probe into its new position with a set screw (not provided).

Insertion Flow Meter Application
FLOW PROFILE AND INSTALLATION
CONSIDERATIONS
Insertion Flow Meters, although generally easier to
install that In-Line Flow Meters, require proper
installation, and a well developed flow profile, in
order to perform properly. Please refer to the section
on the following pages titled PROBE INSERTION
GUIDELINE DRAWING (page 14) and INSTALLATION DEPTH CHART (page 15).
insertion probe will be inserted. Avoid T-Fittings
since they will disturb the flow profile, and effectively reduce the measurement area. Direct threading together (or with necessary bushings) of the
retractor assembly may be required. In other cases,
the threadolet must be welded in place and a clearance hole must be drilled through the pipe/ duct to
accept the probe assembly. If the pipe/duct is under
pressure during installation, a hot tap drill (not
available through Sage Metering) may be required.
SAGE VALVE ASSEMBLY OPERATION
Valve assemblies (SVA05 and SVA05LP) are an optional mounting hardware for Insertion Style Flow
Meters (see pages 38 and 39). They allow the removal
of insertion-style meters for service, cleaning, recalibration, relocation, etc. without the need to “shutdown” your process. The probe insertion depth is
adjustable to permit sensor to be located at center
to optimize measurement accuracy. (Refer to PROBE
INSERTION GUIDELINE DRAWING and CHART, pages
14 & 15.) The ball valve will seal off leaks of the
process gas at the point of insertion after the probe
assembly has been removed. The assembly includes
FLOW CONDITIONING AND STRAIGHT RUN
Although a minimum of 15 pipe diameters of
upstream straight run is commonly recommended,
to absolutely assure that the flow profile is well
developed at the point of measurement, either use
Flow Conditioners (standard in Sage In-Line Flow
Meters, 1/2" and larger, and also available as assemblies for Insertion Flow Meters, see page 13), or
consider additional straight run. The Chart below
provides examples of the amount of straight run
that would virtually assure that there are no flow
disturbances at the point of measurement.

CAPTIVE FLOW CONDITIONERS
Can Be Installed in Conjunction with Insertion Style Flow Meters
IMPORTANT The location of the probe must be exactly one pipe ID diameter (i.e., 4” in a 4” pipe; 6” in
a 6” pipe, etc.) downstream of the Captive Flow Conditioning assembly. The Captive Flow Conditioners
are always designed to be separated by one pipe diameter. See drawing below. The probe location must
be one pipe ID diameter downstream of Flow Conditioner, or errors will occur.

The outputs of the four meters will be averaged
by customer’s PLC or other method to improve
overall accuracy in measuring the flow rate.
(For medium sized round pipes [18" to 36"],
two meters, on the opposite side of the same
diameter, may be sufficient [insert parallel to an
upstream 90 degree bend for optimal benefit.])
Note, in this configuration, each sensor needs
to be averaged.

ing, flanging, welding, etc. DO NOT USE REDUCERS.
IN-LINE FLOW METERS
In-line mounting styles are available through Sage
Metering, Inc. in sizes from 1/4" pipe through 4"
pipe. Threaded male NPT ends are standard up to
2-1/2"; ANSI 150lb flanged ends are recommended
for 3" and 4" models. Contact the factory if optional
end mounting styles are required. Pipe sizes in excess
of 4" require the insertion style mass flow meter.
The in-line style flow meter assembly flow section is
typically specified to match the user’s flow conduit
and is plumbed directly in the flow line by thread-
It includes the sensing element (a self-heated flow
sensor and a temperature/reference sensor) mounted
directly in the specified flow section for exposure to
the process gas; a sensor drive circuit; microprocessor
meter board, and transmitter enclosure.
All in-line Flow Meters, 1/2" and up have built-in
Flow Conditioners. See Table (page 10) for Upstream
Straight run requirements. Note, the 1/4" and 3/8"
do not have Flow Conditioners and thus require
more straight run.
FLOW CONDITIONING SCREENS FOR IN-LINE FLOW BODIES 1/2" AND UP1
LENGTH “L” SAME AS NON-FLANGED METER
(See table on page 35. For example, 1"x8" flow
body has an 8" length.The length will be the same
whether an NPT flow body, or whether flanged.
If a flanged flow body, the 8" dimension will be
a Face-to-Face dimension.)

Features and Benefits
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 (Organic LED) display of Flow Rate, Total and
Temperature in a robust, yet lightweight, dual-sided NEMA 4 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 communications (IEEE
32 Bit Floating Point) and, optionally, HART™.
Sage Prime is CE approved, and CSA, UL approved for Hazardous
Service1 (see “Approvals”under the “Technology” tab on the website). For ATEX Zone I approvals, request Sage Rio Flyer (SIX Series).
CONTINUOUS DIAGNOSTICS & FIELD CONFIGURABILITY
Sage Prime has continuous diagnostics. The raw calibration milliwatts (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”
(0 SCFM) condition, and compare the reading to the original reported
“No Flow” value noted on the last few lines of your meter’s Certificate
of Conformance or the Flow Meter’s data tag. This in-situ diagnostic
procedure not only checks the sensor performance and the “Live
Zero” calibration point, but it also verifies that the sensor is clean.
It essentially provides a means to validate that the meter is operating properly, verifies that there is no shift or drift, and eliminates
the need for annual factory 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
conditions requested, if changes are needed, Addresser software is optionally available for field reconfigurability.

Common Diagnostics
SYMPTOM: Display failure, or pixels extremely dim.
CORRECTIVE ACTION: Contact Factory. Certain types
of failures are under long term warranty. Please note
that the 4-20 mA will still function normally.
SYMPTOM: Display fading, or partially fading.
CORRECTIVE ACTION:
a) Some fading, particularly with those characters that
are lit up most frequently, is normal. The flow
meter will continue to function properly, and flow
meter accuracy and outputs will not be effected.
b) In extreme cases, contact the factory for display
replacement.
c) Note, in late 2009, the Sage Prime was modified
to incorporate a built-in photocell. The purpose
of the photocell is to adjust the display brightness
with ambient lighting. The brighter the surrounding lighting conditions, the brighter the display.
Lower ambient lighting conditions, such as a factory environment, will dim the display. The display will be dimmest if operated in low ambient
lighting, or at night. The photocell circuit is
designed to extend the life of the display, and to
minimize fading.
d) Note, in early 2010, a further enhancement was
added to further extend the life of the display.
The above mentioned built-in photocell also
senses motion which automatically switches display from Screen Saver mode to Normal mode.
SYMPTOM: Erratic Readings.
POSSIBLE CAUSES: If a large Motor or Generator or
Variable Frequency Drive (VFD) is nearby the enclosure, it may be inducing sufficient analog noise into
the circuitry to temporarily corrupt the data.
SUGGESTED CORRECTIVE ACTION:
a) If a Power-Restart temporarily solves the problem,
than it is likely that the source of the noise was
the problem.
b) To prevent subsequent problems, if a Remote
Style Meter, move the enclosure as far away as
possible from the source (the Motor or VFD).
c) If an Integral Style Meter, mount the meter in
a different location (further from the source) or
move the source further from the meter.
SYMPTOM: Erratic Readings on a Remote Meter.
POSSIBLE CAUSE: In some cases, analog noise is
induced into the Remote cable causing erratic, or
climbing readings.
SUGGESTED CORRECTIVE ACTION:
a) Be sure the remote cable is installed in metal conduit and grounded on one end (in some cases,
grounding both ends may be required).
b) Also, avoid coiled cable, especially if not in metal
conduit.
c) Also, if extra cable exists, move the extra cable as
far away as possible from any source of analog
noise, such as large motors or VFDs.
SYMPTOM: Meter reading zero continuously, or Full
Scale continuously, or temperature reading is abnormally low (hundreds of degrees below zero).
POSSIBLE CAUSES/SUGGESTED CORRECTIVE ACTION:
a) It is likely that a wire is loose. But in rare cases,
a sensor could fail (i.e., if a standard sensor, HT01
or HT02 sensor exceeds a process temperature of
450˚F.)
b) Check for continuity to be sure the wiring is
making good contact at the terminals of the
Junction Box.
c) Also, to verify that the electronics and the sensor
serial number are the same, note the following:
The sensor’s serial number will come up upon
power up, right after Initializing on the Display. If
the serial number doesn't agree with the Junction
Box labels, that would affect calibration (in other
words, sensors and electronics are a matched
pair—mixing them up will cause false readings).
Also metal Serial Number Tags are fastened to both
the electronics and the Junction Box. They must
have identical Serial numbers.
d) To check if a sensor has failed on a remote style
meter, it is easy to use the Junction Box to do so.
You must Power Down (shut off power), but you
do not need to remove the probe from the pipe.
Refer to page 24.
44
User Manual
SAGE METERING, INC.
e) An Ohm Meter is required to check across the sensor leads of the Flow Sensor. Look at the drawing
of the Junction Box. Disconnect the red wires on
the Factory Side to isolate and measure the resistance. If the reading is infinity or a short, it means
that sensor has failed.
f) Now check the Temperature Sensor. Disconnect the
white wires on the Factory Side to isolate and measure the resistance. If you have infinity or a short, it
means that sensor is burned out. Note: Normally the
sensors will read approximately 110 ohms at 70˚ F. At
higher temperatures they should read a higher resistance, but both sensors should have a similar value.
g) On integral style meters (SIP), there is no Junction
Box. In that case, refer to the Prime Integral
Terminals on page 19 and check the sensor wires.
Remove the appropriate wires first (red pair for
flow, then white pair for temperature). Measure
their resistance. If reading infinity or short, it
means that sensor has failed.
SYMPTOM: Meter Railing (Pegging) or Reading High
POSSIBLE CAUSES/SUGGESTED CORRECTIVE ACTION:
a) Insufficient straight run (i.e. flow profile is disturbed, causing errors).
b) Possible jet effect if upstream pipe is smaller than
meter flow body or if valve is too close upstream
to meter.
h) Meter is miswired, especially in Remote Style
application.
i)
Possibly caused by water droplets condensing on
inside of pipe wall, which roll down or hit sensor
causing output to spike; but if droplets are near
continuous, output may rail. Note: Recommend installation 45˚ from vertical (see drawing on page 78).
j) Possibly caused by water droplets condensing out
of gas stream and filling the cavity containing the
sensing elements (usually due to probes mounted
below horizontal in saturated pipes).
k) Sensor may be contaminated. Remove probe,
wipe off or clean with a solvent. Reinsert.
l)
Using a different gas or gas mix than the meter
was specified and calibrated for.
m) If a Remote Style Meter (SRP), be sure Serial
Numbers of Junction Box and Remote Electronics
are identical (if not, errors in calibration are inevitable). To confirm, verify that Junction Box
Serial Number Tag has identical Serial Numbers
to Tag on Remote Enclosure.
n) Meter may appear to be reading high if user is
comparing Sage flow meter readings (SCFM) to
an uncorrected volumetric device (ACFM). For
example, at constant volume, a decrease in gas
temperature will increase the mass flow (SCFM).
That is completely normal.
c) Not following Probe Insertion Guideline.
d) If sensor is inserted in reverse (“Upstream” mark
is facing downstream) Meter may over-report (or
under-report) by as much as 30%.
e)
If sensor is not aligned properly, with “Upstream”
mark facing upstream, a rotation greater than
± 5 degrees may cause change in reading
(greater than ± 5 degrees and less than ± 20
degrees causes meter to over-report; a greater
rotation actually blocks the sensor, and causes
meter to under-report).
f) A downstream valve too close to the meter (flow
may be reflecting back).
g) Possibly caused by water droplets condensing out
of gas stream (which generally causes output to
spike; but if droplets are near continuous, output
may rail).
REV. 22-SIP/SRP
SYMPTOM: Reading Low
POSSIBLE CAUSES:
a) Insufficient straight run (i.e. flow profile is
disturbed, causing errors).
b) Poor flow profile Upstream (insufficient upstream
straight run).
c)
Not following Probe Insertion Guideline.
d) If sensor is inserted in reverse (“Upstream” mark

under-report) by as much as 30%.
e) If sensor is not aligned properly, with “Upstream”
mark facing upstream, a rotation greater than ± 5
degrees may cause change in reading (greater than
± 5 degrees and less than ± 20 degrees causes meter
to over-report; a greater rotation actually blocks

i) Meter may appear to be reading low if user is
comparing Sage flow meter readings (SCFM) to
an uncorrected volumetric device (ACFM). For
example, at constant volume, an increase in gas
temperature will lower the mass flow (SCFM).
That is completely normal.
j) On most models, the Totalizer will not start counting for 10 seconds after power up so any flow data
will not be accumulated during this time.
k) Insufficient power supply—most products require
minimum 100 ma.
SAGE METERING, INC.
45
SYMPTOM: Totalizer can take up to 10 seconds to
update its reading when flow meter is first powered
up, or a channel is changed.
CORRECTIVE ACTION: None. This slight delay is completely normal.
SYMPTOM: Display does not have power
POSSIBLE CAUSE: Mis-wiring
SYMPTOM: 4-20 mA output not tracking the flow rate
display
POSSIBLE CAUSE:
a) In normal operation (Self Powered) B4 and B5
must be jumpered to supply power to loop. See
pages 19 and 22.
b) In Externally Powered mode, the jumper must be
removed. Verify that 9 to 27 Volts DC is supplied
to externally power the loop as per page 19 or 22.
SYMPTOM: 4-20 mA output always at 4 mA. Unit has
HART communications.
POSSIBLE CAUSE: Poll address is not set to 0.
l) Excessive load on the 4-20 ma. (To check if problem is due to 4-20 ma output device, temporarily
remove device, and observe if display reads as
expected).

In-Situ Calibration Check
RECOMMENDED ON A QUARTERLY BASIS FOR EPA 40 CFR 98 PERIODIC
CALIBRATION VERIFICATION, CAR1 PROTOCOLS, AND CDM2 PROTOCOLS
Sage Prime has continuous diagnostics. The raw calibration milliwatts (mw) is always displayed in the
upper left hand corner of the meter’s display allowing the user to conduct an “in-situ” calibration. At
any time, you can check this reading at a “no flow”
condition and compare the reading to the original
reported “zero flow” value noted on the last few lines
of your meter’s Certificate of Conformance or the
flow meter's data tag. This diagnostic procedure not
only checks the sensor performance and the “live
zero” calibration point, but it verifies that the sensor
is clean. It essentially provides a means to validate
that the meter is operating properly, verifies that
there is no shift or drift, and eliminates the need for
annual factory calibrations. This simple field diagnostic procedure also verifies that the sensor is free from
contamination, even without inspection.
1. Verify that meter has no gas flow3
Close appropriate valves in the process to have a
“no flow” condition so you can check the “live
zero” mw output of the actual gas (it should be
checked at the same pressure as noted on
Certificate of Conformance).
If it is not possible to close valves in the
process (e.g. natural gas supply must be kept flowing), a user with a Sage SVA05 or SVA07 Isolation
Valve Assembly can check “zero” of the actual gas
and pressure without shutting off the gas supply.
Refer to SVA SERIES ISOLATION VALVE ASSEMBLY
DETAILS ON PAGE 38.
a) Loosen lower Collar Clamp completely4
b) Slightly loosen compression fitting until Probe
can be lifted
c) Lift Probe until Safety Chain is taut
d) Tighten compression fitting
e) Close Valve
f) Check zero mw as per “2” below
Optionally, do an ambient air check by removing probe and covering up sensor by capping
the sensor with a plastic bag, empty plastic water
bottle or other means of preventing flow (see 8).
2. Observe the raw mw on the top of the meter’s
display. After one to three minutes of “no flow”
stabilization, check the observed reading against
the flow meter’s data tag or last line(s) of your
Meter’s Certificate of Conformance.
3. A value within 5 milliwatts of the original Factory
value (assuming the same gas is checked at same
pressure) indicates that meter is still in calibration.
4. A value greater than 5 mw, but less than or equal
to 10 mw, also indicates that the meter is still in
REV. 22-SIP/SRP
calibration, but this reading may have been influenced by one or more of the following factors: gas
composition, pressure, dirt, non-zero conditions,
and sensor orientation. Any of these factors can
have an effect on mWo. It is a very sensitive data
point; that is why it is such a good check.
5. Note, if all of the above factors were remedied,
it would be expected that the mW zero would
report less than or equal to 5 milliwatts.
6. Note, in some cases, contamination of the sensor
is the only cause of the additional heat transfer
during the “no flow” test. Remove probe, and clean
the sensor (use an appropriate non-corrosive solvent to remove build up). A soft brush can be used
to gently clean the sensing surface, using caution
to avoid damaging the sensor elements (the RTD’s).
7. In summary, if a technician in the field were able
to simulate Sage calibration conditions, he too
would find that the mWo would be within one
mW or very close to that. Since this is not always
possible, we are finding that after considering all
of the field variables, a mWo in the field that is
within 10 mW is an acceptable value (see 9). This
would allow for a check to be done in the pipe
under application conditions.
8. Note, if desired, a second check can be conducted
as well but using ambient air: This validation
method requires that the sensor be removed from
the pipe and inserted in a container such as an
empty plastic water bottle.
9. For CAR1 compliance Sage recommends a quarterly
In-Situ Calibration Check for the following Protocols:
U.S. Landfill Protocol, Version 4.0, Par. 6.2
Mexico Landfill Protocol, Version 1.1, Par. 6.2
U.S. Livestock Protocol, Version 3.0, Par. 6.2
U.S. Livestock Protocol, Version 4.0, Par. 6.3
Mexico Livestock Protocol, Version 2.0, Par. 6.2
As per the protocols, the maximum allowable drift
is 5%. Percent drift can be determined by multiplying the mW change from factory value (see 2)
by 1.0% (i.e. each mW change equals 1% drift).
1 CAR is the Climate Action Reserve. The Climate Action Reserve is a national offsets program working
to ensure integrity, transparency and financial value in the U.S. carbon market. It does this by establishing regulatory-quality standards for the development, quantification and verification of greenhouse gas (GHG) emissions reduction projects in North America. The Climate Action Reserve operates
alongside its sister program, the California Climate Action Registry (California Registry), which was
created by the State of California in 2001 to address climate change through voluntary calculation
and public reporting of emissions.
2 CDM Methodologies, ACM 0001, “Methodological tool to determine the mass flow of a greenhouse
gas in gaseous stream” (EB61 Report, Annex 11, Page 1).
3 Sage "zeros" the meter in a horizontal pipe. If you have a vertical pipe, mW will be slightly lower
at zero (also see note 4).

(Default)
MESSAGE FRAMING
Messages start with a silent interval of at least 3.5
character times followed by 4 fields and then followed by another silent interval of at least 3.5 character times. The first field contains the device
address. The second field contains the function code.
The third field contains the data and byte counts.
The fourth field contains the CRC value.
1 Parity on the Wireless Devices manufactured by Obvius is “None” rather than “Even”. The Sage
default is 19200-8-E-1. Change to 19200-8-N-1 for the Obvius Modhoppers and related wireless
devices.
REV. 22-SIP/SRP
DATA FIELD
The CRC-16 (cyclical redundancy check) field is two
bytes, containing a 16-bit binary value. The CRC
value is calculated by the transmitting device, which
appends the CRC to the message. The receiving
device recalculates a CRC during receipt of the message, and compares the calculated value to the actual
value it received in the CRC field. If the two values
are not equal, the message will be discarded.

Correction Factors For

Digester Gas Calibration
User Manual
Installations Where Pipe
Condensation May Develop
Sage can calibrate for any Digester Gas, Bio Gas or
Landfill Gas Mix. However, it may be helpful to have
correction factors for a typical calibration, in the
event that the composition changes after delivery.
The following examples assume that the initial calibration was set up for 60% CH4 and 40% CO2.
a) 65% CH4 and 35% CO2: Multiply reading by
0.982 to correct it for new composition
b) 70% CH4 and 30% CO2: Multiply reading by
0.965 to correct it for new composition
c) 55% CH4 and 45% CO2: Multiply reading by
1.0185 to correct it for new composition
For smaller changes, the corrections are linear in
between
d) Also, if 100% saturated with H2O vapor (noncondensing), multiply readings by 1.042
e) If 50% saturated with water, multiply reading by
1.021
(Water vapor correction is linear in between)
Also, use the 45 degree mounting method in order to
avoid droplets from hitting the sensor and causing
spikes (see above right)
