Getting Started
UNPACKING YOUR SAGE METER
Your Sage flow meter is a sensitive, yet rugged,
precision built electronic instrument. Upon delivery,
care should be taken when opening the shipping
container and removing your meter. The meter
should be inspected for any damage that may have
occurred during transit. If damage is found, please
contact the carrier immediately to place a claim for
damaged goods. The contents of the container
should be checked against the packing list for any
discrepancies. If there are any questions as to the
contents or configuration of the equipment includ-
ing calibration ranges, or, mounting hardware,
contact Sage Metering as soon as possible. Please
save shipping container and packaging materials
(including PVC tube probe protector on Sage
Insertion Flow Meters) in case the unit needs to
be returned for any reason.
MAINTENANCE
Sage thermal mass flow meters essentially require
little or no maintenance. While the sensing element
is somewhat resistant to dirt and particulate build
up, it may become necessary to clean 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-corrosive solvent for removing the

buildup may be required. A soft brush can be used
to gently clean the sensing element's surface, using
caution to avoid damaging the sensor elements
(the RTDs). If any disassembly is necessary, contact
Sage Metering, Inc. for instructions. In general, it is
recommended that your Sage Thermal Mass Flow
Meter be returned to the factory if cleaning,
repair, or recalibration is needed. This is usually
the most cost-effective and reliable alternative.
CALIBRATION
Sage Rio has continuous diag nostics. The raw
cali bration milliwats (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" con-
dition and compare the reading to the original re -
ported "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
the meter's performance, 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 contamina-
tion, even without inspection. See "In-Situ
Calibration Check" on page 46.
