SELF-POWERED 4-20mA OR
USER POWERED 4-20mA
Please note, Sage Meters are not loop powered.
The 4-20mA outputs can be Self-Powered or User-
Powered. All Sage Meters ship set up for Self-Power.
A jumper is pre-installed to bring 24 VDC to the
4-20mA outputs. If you require isolated 4-20mA
outputs, the Terminal Hook-Up Drawings will
instruct you to remove the jumper and connect to
different terminals. In addition, in the User-Powered
Mode, you will need to supply separate power for
the 4-20mA circuit (between 9 and 27 volts DC).
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 INSTALLA-
TION DEPTH CHART (page 15).
Sage Valve Assembly Operation
Valve assemblies (SVA05) are an optional mounting
hardware available through Sage Metering Inc. (see
pages 34 and 35). They allow the removal of inser-
tion-style meters for service, cleaning, re-calibration,
relocation, etc. without the need to "shut-down"
your process. The probe insertion depth is adjustable
to permit sensor to be located at center to optimize
measurement accuracy. (Refer to PROBE INSERTION
GUIDE LINE 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 a valve, thread -
olet, compression fitting with Teflon ferrule, a cable
restraint, and two collar clamps.

A threaded half coupling (3/4" FNPT) properly sized
to accom modate the isolation valve retractor assem-
bly must be fitted to the pipe/duct to which the
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 bush-
ings) 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 installa-
tion, a hot tap drill (not available through
Sage Metering) may be required.
IN-LINE FLOW METER APPLICATION
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. ANSI 150lb
flanged ends are optional, all commonly requested
on 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
