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 Rio 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 Rio 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.

It is recommended that the flow meter be inserted in
a location of maximum straight run. It is suggested
that there be 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).
Check the orientation1: Standard calibration flow
direction is left to right when facing the flow
meter. Gas flow direction is marked with an arrow
on in-line flow meters; UPSTREAM is marked on
insertion probes.
Do not rotate probe1, or errors may occur. If enclosure is facing incorrectly, rotate the enclosure 180˚,
but do not rotate the probe. The UPSTREAM mark
still needs to be facing Upstream.
Hook up the system per the wiring diagram provided with your Sage flow meter (see inside of rear
compartment cover for terminal designation).
Double check that wiring for the proper power and
signal connections are correct.

LOCATING PROPER WIRING DIAGRAM
1) Look at the sticker on your meter. The first three
digits describe the basic model that you have.
Refer to the appropriate page numbers below for
your wiring diagram
2) SIX: see page 19
3) SRX: see page 22 for input/output terminals;
see page 24 (Junction Box Wiring Terminals
for Remote Style Meters)
WIRING
Follow the instructions below to remove the rear cap
for wiring. CAUTION: Do not open the display side!
Before removing the rear cap to access the wiring
terminals it is essential to loosen the set screw used
to lock down the cap. After the wiring is completed
(see pages 18 to 23 for wiring details), please close
the lid, and re-tighten the set screw in the same
manner.
The intended use of the SIX/SRX is for industrial
applications in hazardous atmospheres of up to
zone 1: gas, vapors, and mists. Note: See page 31 for
Hazardous Location Approvals.
■
Check that all plumbing and electrical hook-ups
are in accordance with OSHA, NFPA, and all other
safety requirements.
Customer repair of the product (or replacement of
components) is not allowed. If the equipment is
used in a manner not specified by the manufacturer,
the protection provided by the equipment may be
impaired. Permanently connected equipment shall
employ a switch or circuit breaker as a means for
disconnection in the installment.
■
For Remote Style Meters (SRX) be sure the Remote
Electronics is matched with the Transmitter’s
Junction Box and its attached Probe or Flow
Body. There will be Metal Serial Number Tags
on both the Transmitter as well as the Remote
Electronics enclosure. Do not mismatch the serial numbers of the Remote Electronics and the
Junction Box, or calibration errors will occur.
1 The Integral Style of Sage Rio 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 Rio 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.

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,
REV. 08-SIX/SRX
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.)

and Green wires, and also short together the Black and Orange wires. These extra wires are part of the
meter's Lead Length Compensation circuitry, allowing the user to change the length of the interconnect
cable (from 0 to 1000 feet) without effecting the accuracy. 25 feet of cable are initially supplied (for
cabling longer than 1000 feet, contact Sage).

Principle of Operation of the Thermal Mass Flow Meter
Sage Thermal Mass Flow Meters have two sensors

(RTDs). The two RTDs are clad in a protective 316SS
tions in gas temperature. It is the “job” of the Sage
or Hastelloy C sheath and are driven by a proprietary
proprietary sensor drive circuit to maintain the
sensor drive circuit. One of the sensors is self-heated
differential, whether or not the gas temperature
(flow sensor), and the other sensor (temperature/
changes, or however quickly molecules cool off the
reference sensor) measures the gas temperature.

The pair is referred to as the sensing element, and

cools down as it loses energy. The sensor drive
circuit replenishes the lost energy by heating the
flow sensor until it is a constant temperature differential above the reference sensor. The electrical
power required to maintain a constant temperature
differential is directly proportional to the gas mass
flow rate and is linearized to be the output signal
of the meter.

Features and Benefits
SAGE RIO THERMAL MASS FLOW METER FOR GASES
The Sage Rio Thermal Mass Flow Meter provides the same levels of
performance found in the popular Sage Prime with the added ATEX
Zone 1 Flameproof approvals. The Rio features a bright, high contrast, photo-emissive OLED (Organic LED) display of Flow Rate, Total
and Temperature in an explosion proof, dual-sided IP66 (NEMA 4X)
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. It is powered by 24 VDC
(115/230 VAC optional). The power dissipation is under 2.5 watts
(e.g. under 100 mA at 24 VDC).
Standard outputs include 4-20 mA with HART communication1,
pulsed outputs of totalized flow and full Modbus compliant RS485
communication.
Sage Rio is Zone 1 approved: II 2G Ex d IIB+H2 T6 Gb.
T6 Rating is suitable for gases with ignition temperature as low as
185°F (85°C).
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 RIO

CONTINUOUS DIAGNOSTICS & FIELD CONFIGURABILITY
Rio 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 Rio is fully configured upon shipment for the pipe
and process conditions requested, if changes are needed, HART or
Addresser software is optionally available.

Sage Rio Styles and Specifications
SAGE METERING is a manufacturer of high performance Thermal Mass Flow Meters
which measure the flow rate and consumption of gases for multiple industrial applications. Frequently used for energy management systems to monitor and improve
energy efficiency as well as for regulatory compliance in environmental systems
including reporting of Greenhouse Gas Emissions.
TYPICAL APPLICATIONS include measurement and sub-metering of natural gas
and compressed air for energy utilization and cost accounting within a facility.
Measurement of combustion air flow can be used for improving efficiency in boilers
and furnaces. Environmental reporting of Greenhouse Gases from combustion
sources as well as measurement for carbon credits are frequently encountered.
OTHER KEY environmental applications include flare gas flow measurement in the
Oil and Gas Industry where thermal technology offers economic advantages over traditional flow measurement technology. To meet the regulatory requirements of periodic re-calibration or calibration verification, Sage Metering has developed a unique
in-situ accuracy verification process to ensure the meter is performing within the
original NIST traceable gas calibration while the process remains in operation.

DIAGNOSTICS
Operations and Instruction Manual
SAGE METERING, INC.
41
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 Rio 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).
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.
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.
REV. 08-SIX/SRX
42
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 (SIX), there is no Junction
Box. In that case, refer to the Rio 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.
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).
REV. 08-SIX/SRX
Operations and Instruction Manual
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).
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 (SRX), 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.
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
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).
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.
f) Sensor may be contaminated. Remove probe, wipe
off or clean with a solvent. Reinsert.
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.
g) Using a different gas or gas mix than the meter
was specified and calibrated for.
h) If a Remote Style Meter (SRX), 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.
SYMPTOM: 4–20 mA output always at 4 mA. Unit has
HART communications.
POSSIBLE CAUSE: Poll address is not set to 0.
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.
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).
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

In-Situ Calibration Check
RECOMMENDED ON A QUARTERLY BASIS FOR EPA 40 CFR 98 PERIODIC
CALIBRATION VERIFICATION, CAR1 PROTOCOLS, AND CDM2 PROTOCOLS
Sage RIO 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. 08-SIX/SRX
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).
4 The allen wrench to loosen collar clamp is 9⁄64 on the SVA05 (it is 3⁄16 on the SVA07).

*NOTE: Sage Rio Meters are factory programmed with the MODBUS slave address = 48 (0x30).
It may be extremely useful to be able to write to an unknown slave address with a simple broadcast
command. Be sure only one Sage Rio is connected during any broadcast writes using slave

Writing into unspecified registers (not defined above)
can render the unit non-functional or overwrite factory calibration data yielding incorrect operation.

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

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
