We are pleased that you have pur hased a Sage Metering Mass Flow Meter for your
requirement. We hope that you are satisfied with the performan e, operation and
design of our highly pre ise, NIST tra eable Thermal Gas Mass Flow Meter.
Sage Metering is your sour e for monitoring, measuring and ontrolling the gas mass
flow in your industrial pro ess, building management system or environmental appli -
ation. Our high performan e, NIST Tra eable,Thermal Mass Flow Meters will help
in rease produ tivity, redu e energy osts, maximize produ t yields, and/ or help redu e
environmental insult. Sage provides high quality In-Line and Insertion Thermal Mass
Flow Meters for a wide variety of industrial, ommer ial, and environmental monitoring
needs, in luding arbon redit verifi ation for Greenhouse Gas redu tion.
Sage Meters measure mass flow dire tly — there is no need for an illary instrumentation
su h as temperature or pressure transmitters. Furthermore, our instruments have ex ep-
tional signal sensitivity, have no moving parts, require little if any maintenan e, have
negligible pressure drop and have a turndown up to 100 to 1, and resolve as mu h as
1000 to 1. Sage Flow Meters an measure the mass flow rate and onsumption of air,
oxygen, natural gas, nitrogen, digester gas, biogas, flare gas, hydrogen, argon, arbon
dioxide and other gases and gas mixes.
Sage Rio is the latest addition to our family of high performan e Thermal Mass Flow
Meters. It features a bright graphi al display of Flow Rate,Total and Temperature, robust
industrial en losure, and easy to a ess power and output terminals. Sage Rio has a
dual- ompartment windowed en losure featuring a very high ontrast photo-emissive
OLED display with a new photo ell a tivated S reen Saver. The rear ompartment,
whi h is separated from the ele troni s, has large, easy to a ess and well marked ter -
minals, for ease of ustomer 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.)

UNPACKING YOUR SAGE METER
Your Sage flow meter is a sensitive, yet rugged,
pre ision built ele troni instrument. Upon delivery,
are should be taken when opening the shipping
ontainer and removing your meter. The meter
should be inspe ted for any damage that may have
o urred during transit. If damage is found, please
onta t the arrier immediately to pla e a laim for
damaged goods. The ontents of the ontainer
should be he ked against the pa king list for any
dis repan ies. If there are any questions as to the
ontents or onfiguration of the equipment in lud-
ing alibration ranges, or, mounting hardware,
onta t Sage Metering as soon as possible. Please
save shipping ontainer and pa kaging materials
(in luding PVC tube probe prote tor on Sage
Insertion Flow Meters) in ase the unit needs to
be returned for any reason.
MAINTENANCE
Sage thermal mass flow meters essentially require
little or no maintenan e. While the sensing element
is somewhat resistant to dirt and parti ulate build
up, it may be ome ne essary to lean it from time to
time if mounted in extremely dirty environments.
NOTE: ALWAYS REMOVE THE POWER PRIOR TO
ANY CLEANING OR MAINTENANCE. A detergent or
appropriate non- orrosive solvent for removing the
buildup may be required. A soft brush an be used
to gently lean the sensing element’s surfa e, using
aution to avoid damaging the sensor elements
(the RTDs). If any disassembly is ne essary, onta t
Sage Metering, In . for instru tions. In general, it is
recommended that your Sage Thermal Mass Flow
Meter be returned to the actory i cleaning,
repair, or recalibration is needed. This is usually
the most cost-e ective and reliable alternative.
CALIBRATION
Sage Rio has ontinuous diag nosti s. The raw
ali bration milliwats (mw) is always displayed in the
upper left hand orner of the meter's display. At any
time, you an he k this reading at a “no flow” on-
dition and ompare the reading to the original re -
ported “zero flow” value noted on the last few lines
of your meter’s Certifi ate of Conforman e or the
flow meter’s data tag. This diagnosti pro edure not
only he ks the sensor performan e and the “live
zero” alibration point, but it verifies that the sensor
is lean. It essentially provides a means to validate
the meter’s performan e, verifies that there is no shift
or drift, and eliminates the need for annual fa tory
alibrations. This simple field diagnosti pro edure
also verifies that the sensor is free from ontamina-
tion, even without inspe tion. See “In-Situ
Calibration Che k” on page 46.
Getting Started
CAUTION If installing in a Class I hazardous location the installation
must comply with appropriate electrical codes.
CAUTION Installer must supply proper ground and bond wire for the
transmitter and the sensor per appropriate electrical codes
Cable entires must be used which maintain the ingress protection of the
enclosure to at least IP66.
Unused cable entries must be filled with suitable blanking plugs which
maintain the ingress protection of the enclosure to at least IP66.

INSTALLATION AND MOUNTING
The EN 60079-14 must be considered
■Che k the Certifi ate of Conforman e in luded
with your Sage Thermal Mass Flow Meter for
system pressure, temperature, gas omposition,
power input, and signal output.
■It is re ommended that the flow meter be inserted in
a lo ation 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 onditions. See hart on page 11.
Note, obstru tions su h as valves, blowers, expand -
ers and PVC and HDPE pipes will require addition-
al straight run ( onta t fa tory for assistan e).
■Che k the orientation1: Standard alibration flow
dire tion is left to right when fa ing the flow
meter. Gas flow dire tion is marked with an arrow
on in-line flow meters; UPSTREAM is marked on
insertion probes.
■Do not rotate probe1, or errors may o ur. If en lo-
sure is fa ing in orre tly, rotate the en losure 180˚,
but do not rotate the probe. The UPSTREAM mark
still needs to be fa ing Upstream.
■Hook up the system per the wiring diagram pro-
vided with your Sage flow meter (see inside of rear
ompartment over for terminal designation).
Double he k that wiring for the proper power and
signal onne tions are orre t.
■Che k that all plumbing and ele tri al hook-ups
are in a ordan e with OSHA, NFPA, and all other
safety requirements.
■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 seri-
al numbers o the Remote Electronics and the
Junction Box, or calibration errors will occur.
LOCATING PROPER WIRING DIAGRAM
1) Look at the sti ker on your meter. The first three
digits des ribe the basi 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 (Jun tion Box Wiring Terminals
for Remote Style Meters)
4) SIX/SRX HART: see page 64–65
WIRING
Follow the instru tions below to remove the rear ap
for wiring. CAUTION: Do not open the display side!
Before removing the rear ap to a ess the wiring
terminals it is essential to loosen the set s rew used
to lo k down the ap. After the wiring is ompleted
(see pages 18 to 23 for wiring details or pages 64–65
for HART), please lose the lid, and re-tighten the set
s rew in the same manner.
The intended use of the SIX/SRX is for industrial
appli ations in hazardous atmospheres of up to
zone 1: gas, vapors, and mists. Note: See page 31 f r
Hazard us L cati n Appr vals.
Customer repair of the produ t (or repla ement of
omponents) is not allowed. If the equipment is
used in a manner not spe ified by the manufa turer,
the prote tion provided by the equipment may be
impaired. Permanently onne ted equipment shall
employ a swit h or ir uit breaker as a means for
dis onne tion in the installment.
1The 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 orienta-
tion. Lock the probe into its new position with a set screw (not provided).

LOW PRO ILE AND INSTALLATION
CONSIDERATIONS
Insertion Flow Meters, although generally easier to
install than In-Line Flow Meters, require proper
installation, and a well developed flow profile, in
order to perform properly. Please refer to the se tion
on the following pages titled PROBE INSERTION
GUIDELINE DRAWING (page 14) and INSTALLA-
TION DEPTH CHART (page 15).
SAGE VALVE ASSEMBLY OPERATION
Valve assemblies (SVA05 and SVA05LP) are an op -
tional mounting hardware for Insertion Style Flow
Meters (see pages 36 and 37). They allow the removal
of insertion-style meters for servi e, leaning, re ali -
bration, relo ation, et . without the need to “shut-
down” your pro ess. The probe insertion depth is
adjustable to permit sensor to be lo ated at enter to
optimize measurement a ura y. (Refer to PROBE
INSERTION GUIDE LINE DRAWING and CHART, pages
14 & 15.) The ball valve will seal off leaks of the
pro ess gas at the point of insertion after the probe
assembly has been removed. The assembly in ludes
a valve, threadolet, ompression fitting with Teflon
ferrule, a able restraint, and two ollar lamps.
A threaded half oupling (3/4" FNPT) properly sized
to a om modate the isolation valve retra tor assem-
bly must be fitted to the pipe/du t to whi h the
insertion probe will be inserted. Avoid T-Fittings
since they will disturb the flow profile, and e ec-
tively reduce the measurement area. Dire t thread-
ing together (or with ne essary bushings) of the
retra tor assembly may be required. In other ases,
the threadolet must be welded in pla e and a lear-
an e hole must be drilled through the pipe/ du t to
a ept the probe assembly. I the pipe/duct is under
pressure during installation, a hot tap drill (not
available through Sage Metering) may be required.
LOW CONDITIONING AND STRAIGHT RUN
Although a minimum of 15 pipe diameters of
upstream straight run is ommonly re ommended,
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 assem-
blies for Insertion Flow Meters, see page 13), or
onsider additional straight run. The Chart below
provides examples of the amount of straight run
that would virtually assure that there are no flow
disturban es at the point of measurement.

COMPRESSION ITTING OPERATION
A bored through tube fitting, properly sized to
a ommodate an insertion probe’s parti ular OD,
an be provided by the user or pur hased as an
option from Sage Metering (see page 38). Prior to
installation, a learan e hole to a ommodate the
insertion probe assembly must be drilled in the
pipe/du t. A fitting (1/2" FNPT) is then welded in
pla e or threaded into the half-threadolet whi h has
been welded to the pipe/du t. The probe insertion
depth is adjustable to permit sensor to be lo ated at
enter, to optimize measurement a ura y. (Refer to
PROBE INSERTION GUIDELINE DRAWING and
CHART, pages 14 & 15.)
nsert the probe shaft tubing into the
compression fitting to the position indicated
in the Probe nsertion guidelines.
While holding the fitting body steady,
tighten the nut one and one-quarter
turns to the 9 o’clock position.
INSTALLATION INSTRUCTIONS
1. Insert tubing into the tube fitting.
2. Make sure that the tubing is positioned properly
per the PROBE INSERTION GUIDELINE DRAW-
ING AND CHART, pages 14 & 15.
3. Due to the variations o tubing diameters, a
common starting point is desirable. There ore,
tighten the nut until the tubing will not turn
by hand or move axially in the fitting.
4. S ribe the nut at the 6 o’ lo k position.
5. While holding fitting body steady, tighten the nut
11⁄4turns to the 9 o’ lo k position.

Sage insertion style flow meters an be assembled
and alibrated for use in virtually any size pipe or
du t (as small as 1”). Sage insertion flow meters
in lude a probe assembly that supports the sensing
element (a self-heated flow sensor and a tempera -
ture/referen e sensor); a sensor drive ir uit; mi ro -
pro essor meter board, and trans mitter en losure.
The probe assembly must be inserted into the orre t
position in the pro ess gas flow onduit to allow the
gas to flow through the sensor “window” a ross the
sensor element. The “sensing point” or a tive part of
the sensor (0.5" from the end of the probe) should be
positioned as per the drawing below and the
Installation Depth Chart on page 15.
Installation Depth
The enter of the pipe (assuming a well developed
turbulent flow profile) is fairly flat, and easy to
lo ate. See “Installation Depth Chart” on next
page to determine proper
insertion depth.
PROBE INSERTION GUIDELINE DRAWING1
Choose the longest straight-run se tion of pipe avail-
able to allow a uniform, well-developed flow profile.
Allow for a minimum of 15 pipe diameters of straight
run upstream, and 5 diameters downstream, depend-
ing on the onditions. See hart on page 11. Note,
obstru tions su h as valves, blowers expanders and
PVC and HDPE pipes will require additional straight
run ( onta t fa tory for assistan e). Avoid, if possible,
installations immediately downstream of bends, fans,
nozzles, heaters and espe ially valves, or anything
else installed in the line that may ause nonuniform
flow profiles and swirls. Otherwise signal output
errors ould result, unless signifi antly more straight
run is provided, or in the absen e of suffi ient straight
run, Flow Conditioners (page 13) are in stalled ( on-
ta t Sage for assistan e if needed). Refer to page 13 to
see the benefits of in orporating Flow Conditioners.
Insertion styles are available through Sage Metering,
In . with a standard 1/2" OD probe support assem-
bly. Standard probe lengths are 6", 12", 15", 18",
24", 30" and 36". A ommon method of mounting

IN-LINE LOW METERS
In-line mounting styles are available through Sage
Metering, In . 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 re ommended
for 3" and 4" models. Conta t the fa tory if optional
end mounting styles are required. Pipe sizes in ex ess
of 4" require the insertion style mass flow meter.
The in-line style flow meter assembly flow se tion is
typi ally spe ified to mat h the user’s flow onduit

LENGTH “L” SAME AS N N-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.)

Remove jumper for Externally Sourced 4-20

externally power the 4-20 mA loop, and the

On units with HART this jumper has been

2It is important to connect the Ground when using Modbus communications or ground loop problems
may develop. Improper wiring can also damage internal circuitry
3Note, if customer externally powers the 4-20 mA by removing the jumper the Pulse voltage output
is also effected: The voltage output of the Pulse will follow the customer power (i.e. 24 VDC external
power will result in a 24 VDC Pulse [maximum of 50 mA]; 12 VDC external power will result in a

Cutoff can be entered into the FLOW MIN Functions. In Versions 1.82 or higher the Low Flow Cutoff
and the 4-20 mA Scaling are independent of each other. For example: A Low Flow Cutoff (LFC) of
10 SCFM on a Meter with a Full Scale of 100 SCFM will report 0 on the Display and 4 mA on the
output. The output will remain at 4 mA until the LFC is exceeded: (ie: 25 SCFM=8 mA). Thus the
4 mA will always be zero based
