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 tempera -
ture/reference sensor); a sensor drive circuit; micro -
pro cessor meter board, and trans mitter enclosure.
The probe assembly must be inserted into the correct
position in the pro cess 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
Installation Depth Chart on page 15.
Installation Depth
The center of the pipe (assuming a well developed
turbulent flow profile) is fairly flat, and easy to
locate. See “Installation Depth Chart” on next
page to determine proper
insertion depth.

Choose the longest straight-run section 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 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 sufficient straight
run, Flow Conditioners (page 13) are in stalled (con-
tact Sage for assistance if needed). Refer to page 13 to
see the benefits of incorporating Flow Conditioners.
Insertion styles are available through Sage Metering,
Inc. with a standard 1/2" OD probe support assem-
bly. Standard probe lengths are 6", 12", 15", 18",
24", 30" and 36". A common method of mounting
the probe assembly through a pipe wall or duct (if
ambient air)is with a compression fitting (STCF05).
A Sage valve assembly (SVA05)is useful and highly
recommended for pressurized applica-
tions or other gases, such as Natural Gas.
Flange mounting is optionally available.
Provided with
explosion proof
plugs on each side.
