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 Clear is our most economical, and 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, NEMA 4 enclosure, and easy to access power and output
terminals. Sage Clear features a very high contrast photo-emissive OLED display with a
photocell activated Screen Saver. The terminals are easy to access and well marked for
ease of customer wiring. It is powered by 24 VDC (or optionally 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

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 37 and 38). They allow the removal
of Insertion-style meters for service, cleaning, recalibration, relocation, etc. without the need to
“shut-down” 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
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.
includes a valve, threadolet, compression fitting
with Teflon ferrule, a cable restraint, and two

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.

Choose the longest straight-run section of pipe available to allow a uniform, well-developed flow profile.
Allow for a minimum of 15 pipe diameters of
straight run upstream, and 5 diameters downstream,
depending on the conditions. See chart on page 11.
Note, obstructions such as valves, blowers expanders
and PVC and HDPE pipes will require additional
straight run (contact factory for assistance). Avoid, if
possible, installations immediately downstream of
bends, fans, nozzles, heaters and especially valves,
or anything else installed in the line that may cause
nonuniform flow profiles and swirls. Otherwise signal output errors could result, unless significantly
more straight run is provided, or in the absence of

Sage insertion style flow meters can be assembled
and calibrated for use in virtually any size pipe or
duct (as small as 1”). Sage insertion flow meters
include a probe assembly that supports the sensing
element (a self-heated flow sensor and a temperature/reference sensor); a sensor drive circuit; microprocessor meter board, and transmitter enclosure.
The probe assembly must be inserted into the correct
position in the process gas flow conduit to allow the
gas to flow through the sensor “window” across the
sensor element. The “sensing point” or active part of
the sensor (0.5" from the end of the probe) should be
positioned as per the drawing below and the

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.

In-Line Flow Meter Application
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 11) 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.)

CLEAR Mounting Instructions
A 6-32 Pan Head Phillips machine screw is recommended for each corner of the SRA remote enclosure.
The screw will have to pass through .40 inches
(roughly 19/64") of overall thickness at the bottom
of the enclosure mounting hole before the screw
threads emerge. The thickness of the enclosure material is 1/8". The over-all length of the screw depends
on the customers mounting configuration and how
much depth they have to penetrate on their mounting plate that the enclosure is being fastened to.

DIAGNOSTICS
Operations and Instruction Manual
SAGE METERING, INC.

Common Diagnostics
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) Note, in early 2010, the Sage Clear features an
enhancement that was added to extend the life of
the display. It includes a built-in photocell that
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, or turn
Power switch OFF), but you do not need to
remove the probe from the pipe. Refer to page 24.
REV. 02-SIA/SRA
44
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 on page 24. 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 (SIA), there is no Junction
Box. In that case, refer to the Clear 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.
Operations and Instruction Manual
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 55).
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. 02-SIA/SRA
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

In-Situ Calibration Check
VERIFY SENSOR FUNCTIONALITY AND FLOW METER CALIBRATION AT A “NO FLOW” (0) CONDITION
Sage Clear 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 flow1—“In-Situ” Method.
(Also see “Ex-Situ” Method in item 8.)
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 37.
a) Loosen lower Collar Clamp completely
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 milliwatts (mw) on the top of the
meter’s display. After a few 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 the meter is still
REV. 02-SIA/SRA
in calibration.
4. A value greater than 5 milliwatts, but less than
or equal to 10 milliwatts, also indicates that the
meter is still in 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 and 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 the probe, and
clean the sensor (use an appropriate non-corrosive
solvent to remove the 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. Alternate “Ex-Situ” Method: If desired, an alternate check can be conducted, 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 CAR2 compliance Sage recommends a quarterly In-Situ Calibration Check per the Landfill
Project Protocol, Version 4.0, Paragraph 6.2. As
per the protocol, 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 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).

Sage Metering Technical Contact
Take special care when packaging your meter for return to the factory. The sensor in particular may easily
be damaged if not prevented from shifting around within the package and if the sensor itself is not covered to keep it from contacting other package contents. Any damage resulting from improper packaging
is the responsibility of the shipper.

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)
