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 and control 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.
The innovative Sage design (whether configured as an In-Line or Insertion Flow Meter)
provides high accuracy and repeatability for optimum measurement and control of
your process and offers a large-format back-lit display of mass flow, total and temperature. Isolated 4-20mA outputs of flow and temperature are standard. In addition,
pulsed outputs of consumption are available off of the Relay contacts. Furthermore,
the Sage Meter includes a user-friendly Touch Display Screen keypad and powerful
menuing system to integrate the functions of flow measurement with your specific
needs. For even greater flexibility, multiple channels (up to four calibrations) are
available in one meter.
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. (To access this manual on the website, enter in the
user name “sage” followed by the passcode “7243737” when prompted.)

INSTALLATION AND MOUNTING
■
Check the Certificate of Conformance included
with your Sage Thermal Mass Flow Meter for
system pressure, temperature, gas composition,
power input, and signal output.
■
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 12. Note, obstructions such as
valves, blowers, expanders and PVC and HDPE
pipes will require additional straight run (contact
factory for assistance).
■
Check the orientation: 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 probe, 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. Double check
that wiring for the proper power and signal connections are correct.
■
Check that all plumbing and electrical hook-ups
are in accordance with OSHA, NFPA, and all other
safety requirements.
■
For Remote Style Meters (SRG) be sure the
Remote Electronics is matched with the
Transducer’s Junction Box and its attached
Probe or Flow Body. There will be Metal Serial
Number Tags on both the Transducer 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.

INSERTION FLOW METER APPLICATION
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 12. 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
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

2. Probe should be inserted per Installation Depth Chart (see following page),
so sensors are in the center of the pipe.
3. The portion of the probe that remains outside of the pipe, is simply the factory
ordered probe length (i.e. “-15” = 15 inches) minus the “Y” dimension.
4. If gas stream is prone to condensation, the pipe walls tend to form droplets which
may roll down probe support and hit sensors (this can be avoided by keeping pipe
wall above 32˚F). The output would read maximum flow until the droplet evaporates
(usually about 5 minutes). To prevent the droplets from hitting the sensors, install the
probe with a 30-45˚ tilt (moving probe forward or backward).

THERMAL MASS FLOW METERS
HOW DOES THERMAL MASS FLOW
MEASUREMENT BENEFIT YOU?
Sage Thermal Mass Flow Meters are designed for high
• Direct Mass Flow—No need for separate tempera-
performance mass flow measurement of flow rate and
consumption of gases such as natural gas, air, oxy-
ture or pressure transmitters
• High Accuracy and Repeatability—Precision meas-
gen, digester gas, landfill gas, biogas, gas mixes, flare
urement and optimal control of your process
gas, nitrogen, carbon dioxide, oxygen and hydrogen.
• Turn down of up to 100 to 1 and resolution as
much as 1000 to 1
Sage Metering has distinguished itself by offering a
higher standard – our mass flow meter output is unaffected by even large process temperature variations,
and our digital electronics is impervious to external
analog noise. Fast response, high resolution, and
ultra sensitivity are features that are at the heart of
every Sage Thermal Mass Flow Meter.
• Low-End Sensitivity—Detects leaks, and measures
as low as 5 SFPM!
• Negligible Pressure Drop—Will not impede the
flow nor waste energy
• No Moving Parts—Eliminates costly bearing replacements, and prevents undetected accuracy shifts
• Dirt Insensitive—Provides sustained performance
• Low cost of ownership
All Sage meters, depending on product style, can be
reconfigured in the field (contact Sage for details
• Ease of Installation and Convenient Mounting
Hardware
concerning software and related accessories). In addition, all meters have a convenient in-situ field diagnostic procedure that verifies that the original factory
calibration hasn’t drifted, shifted, or changed. This
“Sensor Functionality and Zero Self Check” also verifies that the sensor is free from contamination, even
without inspection. All Sage Flow Meters are offered
in the Integral Style or Remote Style (with leadlength compensation up to 1000 feet) with explosion
proof Junction Box with your choice of Probe or
Flow Body depending on your pipe size.
Features and Benefits
The innovative Sage design features an easy-to-use
menuing system, a mass flow, total and temperature display, and 4-button keypad to integrate the
functions of flow measurement with your specific
needs. You will have the flexibility to use the local
display/keypad (if enclosure removed), or a laptop,
to change configurations or to conduct basic diagnostics, including a calibration self-check, with a
simple routine using the keypad. At any time you
can use the convenient menuing system to change
full scale values, digitally filter the flow signal,
change decimal points, set Low Flow cutoffs, check
diagnostics, or reconfigure an insertion meter for
a different pipe size.

2If bottom of VIP screen is not visible (i.e., prompt not visible, and
flow rate and total and temperature not visible), change computer
to a 96 font DPI setting (Control Panel, Display, Settings, Advanced,
DPI Settings, 96).
3If you change Max Val higher than original (Full Scale) calibration
range, you may lose some accuracy since the calibration data is now
being extrapolated. However, it allows the Flow Rate Display to continue, and also resets the 4-20mA to the new setting. Contact Sage
for details.
4K-factor (304) affects display, and recomputes Max Val (210) to
maintain original 4-20mA setting. If new 4-20mA setting desired
to track display, then change Max Val (210) back to original setting.
(i.e., if original Max Value was 100, a K factor of .5 changes Max
Value to 50.) See next section for more detail.
5Do not change item 306. See item 619 to change filtering. Note
item 702 adjusts update period, and often is useful if the issue
relates to display or output changing too rapidly.
6Reset Total resets the totalizer to zero. If you want to disable the
totalizer, see footnote 11 on this page. Also see note 10 on page 71.
7Newer versions of the meters may have some changes in Menu 600.
Contact Factory for latest version. (Note: The 600 Menu is primarily
used by the Factory, except for item 619 which adjusts filtering [useful to
dampen fluctuating flows.])
8If Factory authorizes entering of new coefficients, it is best to use
VIP software to enter values in 613 to 618 rather than keypad to
prevent truncating of least significant digits.

201
Rate Prec—The number of decimal points for the flow
rate (top line) reading (max 3).
202
Total Prec—The number of decimal points for the total
display (bottom line) reading (max 2).
210
Temp Deg—This controls whether the displayed temperature reads in Fahrenheit or Centigrade. If “0” is selected,
the temperature reading will always be blank. (Note:
The temperature readying will also blank if the totalizer
exceeds a value that requires 7 digits (i.e., 99999.9 or
9999999). The next count will cause the entire temperature display to blank. (The temperature will be restored
once the totalizer is reset, or if the totalizer “rolls over”
[exceeds 12 digits]).
221
Temp Max—The Full Scale of the temperature. Example
200˚F=20mA.
222
Temp Min—Example 40˚F=4mA.
230
LCD Address—Factory Only.
303
Zero Offset—Factory Only.
304
K-Factor—1) Used to bias the readout. For example, if
meter reads 100, and customer feels 102 is correct, then
change K-Factor to 1.02
Max Val—Full Scale Setting.
a) This value will recalculate when engineering units are
changed. For example, 1000 SCFM Full Scale becomes
60,000 SCFH if the engineering units are changed to
SCFH (the change will be observed after the meter is
put into “Flow Mode” (the normal mode [100 on laptop, or Keypad Shortcut (hold “Forward/Up,” then
press “Flow/Shift”]).
b) This value will also recalculate if pipe area is changed.
For example, a Full Scale of 100 SCFM in a 6" pipe
(.2006 sq. ft.) will have a new full scale of 173.2 SCFM
in an 8" pipe (.3474 sq. ft.).
c) At any time you can change the Max Val (Full Scale
Value) below the original Full Scale Value, adjusted
for the new Engineering units, or below the Full Scale
value adjusted for the new pipe area. If you do so,
you will have a new lower Full Scale (i.e., the new
Value will equal 20mA), and the display will be limited to that value. This change has the effect of lowering the range of the meter. You can raise the Full
Scale Value higher than the original calibration value,
but in that case the readings may be less accurate (see
footnote 3 on page 44). (Note: The original calibration value is noted on the Certificate of Conformance.) In some cases the calibration value may be
higher, if for example there is some uncertainty as to
the proper Full Scale Value. For example, a customer
may request a Full Scale Value of 100 SCFM, but Sage
may add an extra 20% of calibration data (to 120
SCFM). In that case, the Full Scale Value can be
changed up to 120 SCFM.
d) This value will also recalculate when a K-factor (item
304) is entered. For example, a K-factor of .8 will
cause a Full Scale of 100 SCFM to become 80 SCFM.
Be careful, however. You will generally want to restore
the Full Scale setting back to 100 SCFM by manually
changing item 210 back to 100 SCFM, so that 100 SCFM
will still report an output of 20mA (see item 304
description). Otherwise, when the display reads 80
SCFM, the output will read 20mA instead of 16.8mA.
211
220
Min Cutoff—If it is desired to “force” the meter flow rate
to read zero, even if there is a small amount of flow (such
as a leak, some gas convection, higher zero pressure then
specified), then simply select a value. If for example, your
meter is calibrated from 0 to 100 SCFM, by putting a
value of 5 in item 211, any flow up to, or equal to 5
SCFM will display 0 (zero), and thus the totalizer will not
advance. As soon as the actual flow exceeds 5 SCFM, normal operation is restored. This setting does not affect the
4–20mA output. It still reads normally. Note, for the SRE
style meters, there is only one set of 4-20 mA terminals.
These terminals can be configured either for Flow Output or Temperature. If an exact value of 0 is entered
in item 211, the output will be a Temperature output
(i.e., 0.000). However, any other value (i.e., 0.001) will
result in a Flow output.
K-Factor—2) Used to correct gravimetric units (such as
LBS/Min, Kg/Sec, etc.) for gases other than Air. Put in
the specific Gravity of the gas. For example, for Nitrogen,
use 1.037
K-Factor—3) Can be used to correct for for a different
Pipe Area than the meter’s original set up. For example,
if calibrated initially in a 4" Schedule 40 Pipe (.0884 sq.
ft.), and then re-installed into a 6" Schedule 40 Pipe
(.2006 sq. ft.), enter a K-factor to 2.269 (original factory
K-factor was 1.000). Note 2.269 = .2006/.0884. Normally,
you’ll use item 305 for a pipe change
NOTE: THE K-FACTOR IN THE ABOVE EXAMPLES WILL
NOT ONLY BE REFLECTED IN THE DISPLAY, BUT ALSO
IN THE 4-20 ma OUTPUT
305
Pipe Area—The pipe area must be changed any time the
meter is inserted into a different pipe than originally
specified (except for velocity units, such as “SFPM”). For
example, if the original pipe area was .2006 square feet
(for a 6" Sch 40 pipe), and you decide to insert the meter
in an 8" Sch 40 pipe, change the pipe area to .3474
square feet so the SCFM, (or other flow units) will read
correctly. This will also change the Full Scale (see “210–b”
description). It is best to "Save" (Item 100) immediately
after changing pipe area.
306
DO NOT USE (Unless you have Rev. 2.045).

Reset Total—You can reset the totalizer to zero. Note: by
enabling item 720 (Ext Zero Enable), you can reset the
totalizer externally. That is, you can reset the totalizer
with a contact closure (terminals 15 and 17 on SIG or
SRG). It is recommended that you Reset Total if engineering units are changed (i.e. from SCFM, or vice versa, or

601–612 Factory Only.
613–6182 These are the coefficients (a polynomial that linearizes the raw flow data so the display, and the
4-20mA outputs are linearly proportional to the flow
rate). Do not change these values unless the Factory
authorizes (such as, to extend the calibration curve).
619
Filter Coeff—The filter coefficient is used to smooth
out the flow signal (a value of 0.1000 is normal).
For example, if you have an unusually turbulent
flow, perhaps a pulsating flow, you may want to
smooth out the reading and output by lowering
the value (if you lower it, it smooths [or averages])
the flow reading as well as the output. To speed up
the flow response, increase the value. The speed of
response is limited by the thermal response of the
sensor (maximum of 1 second per time constant
on a step change).

then channel can be selected externally (unless item
720 is set to 1). For SIG and SRG Series, connect 16
to 17 for Channel B, 15 and 17 for Channel C, both
for Channel D, and no connection for Channel A.
(If “A” displayed in top left corner of display, then
meter is in “External Mode”, otherwise blank.)
702
Sample Rate—This setting changes the update period
of the display, as well as the 4-20mA output. Low
Value=Fast; High Value=Slow (10 is the default=200
msec).

Serial Number—Display the Meter Serial Number (the
value cannot be changed). Note, the Serial Number
displays for approximately 2 seconds upon Meter

Delay Time
Delay Time—User must enter a value to set hysteresis
trip time value. All relay trip settings require this value
(see Timer for values and range) for proper operation.
The trip condition must exist for at least Delay Time
value, before the Trip condition will activate. This is
used to minimize the effects of false triggering of the
alarms from spurious peaks in flow or temperature.
Setpoints or timer functions #630-638 may be adjusted only after they are assigned to relay contacts
#621-624. First select Relay #1 or Relay #2 and the
desired coil activation, On or Off. Each relay selection requires a function for proper operation. It is
required that users program the relay settings in
sequence #621..#624 and assign functions to each
setting. If a relay will be unused, assign #630
(Disabled) to the Relay On and Relay Off setpoints.
EXAMPLES
NOTE: The steps in setting the Relay Menu items
needs to be followed in the exact sequence for Relay
Settings to function properly, as noted in the examples below.
Example 1: DEACTIVATE RELAY(S)
Relay #2—Enter Menu item #623 to assign a new
function. Enter #630 (Disable) for function assignment. Next Enter item #624 for next function assignment. Then enter #630 (Disable) to keep the relay coil

Example 9A, 9B, and 9C:
Selecting Channels
If a user simply wants to pre-configure his meter for
three or four pipe configurations, then it is a simple
matter of selecting the channel he is interested in by
changing the value of item 701 (Chan Select) in the
System Setup Menu. If on the other hand, the user
wants a generic meter, calibrated for Velocity Units,
then the user needs to change Pipe Area by changing
the value of item 305 (in sq. ft.) in Flow Basics Menu.
Subsequently user can change the engineering units
(See Menu 400). In some cases, both approaches can
be put in a single meter. For example, Channel A, B
and C can be “pipe-specific”, and Channel D can be
in velocity units. Then you can use both procedures.
However, the example below assumes four pipespecific ranges
Operations and Instruction Manual
3. Tap “Flow/Shift” for Channel A, “Select/Set” for
Channel B, “Forward/Up” for Channel C, or
“Back/Down” for Channel D
4. It will take about 10 seconds to switch channels
after step 3

Channel B: 0–2000 SCFM in a 4" Sch 40 Pipe
Channel C: 0–5000 SCFM in a 6" Sch 40 Pipe
Channel D: 0–8500 SCFM in an 8" Sch 40 Pipe
Example 9A (Current Version):
To select a channel on Meter Rev. 2.066
(for example, Channel B) from the Keypad,
follow the steps below:
1. Verify that Meter is in Flow Mode (see Example 2)
2. Tap the Back/Down Key 4 times (in under 3
seconds)
3. Tap Flow/Shift for Channel A, Select/Set for
Channel B, Forward/Up for Channel C, or

meter into center of a 4" pipe
Example 2:
Changing Channels using Sage VIP
To change channels from Sage VIP (our navigational
software) with the laptop, there is a shortcut:
1. First be sure that the meter is reading Flow (press
space bar, then select 100 at the prompt, to bring
up Flow Mode)
2. Type uppercase B. It will switch to channel B
within 10 seconds
3. To switch to another channel, for example, C,
type upper case C
Example 3:
Changing Channels Externally
Finally, the channels can be switched externally,
by contact closure, using a switch, a PLC, or a relay
(see item 701 on page 44, and enable external
switching by selecting “4” in item 701). The description in item 701 (on page 48) also denotes which
terminals to connect to.
Example 4:
Dual Channel/Dual Sensitivity Meters and
Auto Ranging
Note: Some customers order dual channel/dual sensitivity meters, and using externally latched relays, or
a PLC, can autorange between Channel A and
Channel B. For example, Channel A on a SRG meter
can be ranged for 0-500 SCFM, and have one of the
optional relays programmed in Channel A to TRIP
HIGH at 450 SCFM, thus sending a contact closure to
the PLC. The PLC, in turn, will ground terminal 16
(effectively connecting terminal 16 to terminal 17).
That switches the meter into Channel B, which has a
range of 0-20,000 SCFM. If the flow falls below 400
SCFM, its relay TRIPS LOW, and the PLC removes the
switch closure between Terminal 16 and 17, which
causes the meter to switch back to Channel A. So
this scheme effectively provides an autoranging
meter, and a turndown of 4000 to 1! (5 SCFM to
20,000 SCFM). Alternately external latching relays
could also provide the ability to autorange. (Note, in
this example, Channel A will be factory configured
for a very high sensitivity, by raising the delta T [the
overheat] so as to detect even the slighest movement
of gas.) Channel B will have a much lower delta T.
Thus, when the channels switch back and forth, not
only does the calibration range change—so does the
delta T (the overheat). There is no other feature
which more clearly defines the concept of “Totally
Independent Channels”—for even the overheat
changes when the channels switch back and forth.
1 Note, to unlock the Flow Meter so data can be changed, type in 99999 at the prompt; in a single
channel Flow Meter, the displayed text changes from "Chan A Locked" to "Chan A Active", indicating
that changes can be made.

Common Diagnostics
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 19.
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 has failed. 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 (SIG), there is no Junction
Box. In that case, refer to the Integral Hookup on
page 20 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 an upstream valve is too
close to the 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
REV. 04-SIE/SRE
62
SAGE METERING, INC.
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).
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 73).
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 (SRG), 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.
REV. 04-SIE/SRE
Operations and Instruction Manual
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) Sensor may be contaminated. Remove probe, wipe
off or clean with a solvent. Reinsert.
g) Using a different gas or gas mix than the meter
was specified and calibrated for.
h) If a Remote Style Meter (SRG), 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.
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 24VDC power supply—the SIG & SIP
require 350 ma to operate properly, or 250 ma
with back lite turned off (Menu item 707)
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

RETURNING YOUR SAGE METER
A Return Material Authorization Number (RMA#)
must be obtained prior to returning any equipment
to Sage Metering for any reason. RMA#s may be
obtained by calling Sage Metering at 866-677-7243
or 831-242-2030 between 8:00 am and 5:00 pm
Monday through Friday.
A Sage RMA Form (see page 68) must be filled
out and included with the meter being returned
to Sage Metering. RMA Form is also accessible by
clicking the “Contact Tab” of the Sage Website
(www.sagemetering.com).
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. It is recommended that a section of PVC
pipe be used to protect insertion meters upon
their return. Cut a length of PVC at least 1/2"
longer than the probe. Insert over the entire probe
and properly secure the PVC to the enclosure or
junction box (if an SRP). A properly secured and
measured PVC section will cover the entire probe
as well as the sensor, and will extend 1/2"
(or more) beyond the sensor housing.
A purchase order is required prior to an RMA being
issued. Most repairs or recalibrations can be quoted
over the phone. For equipment that must be evaluated, an Evaluation purchase order in the amount of
$150 is required. Once an evaluation is completed
and a quote has been issued, you can choose to proceed with the work or have the unit returned with
only the evaluation and freight fee billed.
