UNPACKING/INSPECTION
Inspect
• After unpacking the unit, inspect carefully for any damage that may
have occurred during transit. Check for loose, missing or damaged
parts. Shipping damage claims must be filed withcarrier.
• See General Safety Instructions, and all Cautions, Warnings, and
Dangers as shown.
INTRODUCTION
The QSI communications module is a multiple capability electronics package. For
the G2 meter, the module is available with the plain cover plate only. The QSI
module has three versions (QSI1, QSI2 or QSI3) available; each with its own mix
of capabilities to better serve the customer (See Versions below).
• QSI1 is equipped with Bluetooth®, coil/digital pulse input, pulse output (flow or
energy & scalable), RS485 (Modbus® RTU), temperature inputs, BTU
calculator.
• QSI2 is equipped with Bluetooth, coil/digital pulse input, pulse output (flow or
energy & scalable), temperature inputs, BTU calculator.
• QSI3 is equipped with Bluetooth, coil/digital pulse input, pulse output (flow
scalable), 4-20mA output.
This manual contains information and meter wiring diagrams for the three different
QSI electronics modules.
IMPORTANT NOTICE
QSI module electronics are very sensitive to electric noise if operated within 6
inches of some electric motors, relays, transformers or other sources of electronic
noise.
If the QSI electronics are used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
GENERAL INFORMATION
QSI electronics are mounted into the cover plate of the meter you ordered. The
QSI electronics converts the voltage (or pulses) from the meter into usable
information.
The QSI module electronics is powered by customer supplied external power.
SAFETY
•This product is not approved for use in hazardous locations.
•Be sure O-rings and seals are kept in good repair.
•When applying power, adhere to specifications in this manual.
•Disconnect external power before attaching or detaching input or output wires.

INSTALLATION
CAUTION: Installation near high electromagnetic fields and high current fields is
not recommended and may result in inaccurate readings.
NOTE: There is no external visual difference between QSI1, QSI2, or QSI3
communications suites when they are installed.
NOTE: If you ordered a QSI communications suite with your meter, it was installed
at the factory. Please review and thoroughly understand all manuals and
installation instructions before proceeding.
WIRING
All electronic options are associated with a flat style of meter cover plate. This
cover plate has four threaded ports, compatible with PG7 threads, for gaining
wiring access to the electronics inside the cover plate.
The meter is shipped with the ports environmentally sealed with a threaded plug
and seal. Remove one or more of these plugs as required to install the supplied
port fittings below.
Each meter is supplied with cable gland strain reliefs with O-rings and 1/2 NPT
adapters with seals for use in the threaded ports of the meter cover plate.
Select the port fittings that fit your process and replace the threaded plugs in the
cover plate with the fittings as required.
NOTE: The threaded plugs installed at the factory may be left in any unused cover
plate port indefinitely.
It is recommended that a “removable” thread-locker (fluid, stick, tape, spray, etc.)
be used when installing the strain reliefs or adapters into the cover plate ports.
STRAIN RELIEFS
The cable gland strain reliefs will accommodate a cable diameter of 0.11 - 0.26
inches (2.79 - 6.6mm) and provide an environmental seal around the cable when
the dome-nut is tightened.
NPT ADAPTERS
The 1/2 NPT adapter fittings are used for attaching flex conduit to the meter, for
those applications that require cable runs to be enclosed in conduit.
NOTE: Cable to be provided by customer to accommodate job requirements.
Cable is not included with meter.

FLOMEC APP QUICKSTART
TEMPERATURE PROBES
If you ordered a QSI1 or QSI2 electronic module and intend to use the BTU
calculator function in your process, you will need to provide temperature probes
and cables suitable for your process. The cables are not connected to the QSI PC
board.
If the cables used with your probes has a smaller diameter than the standard strain
reliefs (black) provided with your meter, reduced fit strain reliefs (gray) are
available as a kit from the factory.
NOTE: PN 145500-13, Kit, strain relief, temperature sensor. Includes: (2) PG7
thread strain reliefs (reduced fit), .08 - .20 cable diameter range.
INSTALLATION & WIRING
NOTE: The meter should be installed in the system return line for accurate BTU
calculations.
Typically, a temperature probe is installed in the process piping, initially near each
end of the meter to calculate the differential between the two probes (inlet vs
outlet), if any. The differential is captured and shown in the Android application as
“Temp 1” and “Temp 2” and is used in the BTU calculations to ensure an accurate
calculation.
For clarity, one probe is considered PT100 #1 and is connected to the meter PC
board in that location. It is shown as “Temp 1” in the Android application.
The other probe is then considered PT100 #2 and is connected to the meter PC
board in that location. It is shown as “Temp 2” in the Android application.
To perform the differential check, the probe installed near the meter outlet end
should be considered PT100 #1.
The probe installed near the meter inlet end should be considered PT100 #2.
After wiring the probes to the correct terminal of the PC board, perform the
differential check.

12
TEMPERATURE PROBES
INSTALLATION & WIRING - (continued)
After performing the differential check, remove the PT100 #2 probe near the inlet
end of the meter and install the removed probe in the system supply line.
During normal system operation, probe PT100 #1 is installed near the meter outlet
end and probe PT100 #2 is installed in the system supply line. Accurate system
BTU usage is calculated between the (2) probes.
Typically, the probe cables are the same length. Excess cable from the PT100 #1
probe (near the meter outlet) to the cover plate may be coiled and secured using
plastic quick ties.
MAINTENANCE
Check cable-entry seals periodically. Tighten and/or apply sealant if needed. This
is especially important in environments containing heavy concentrations of dust,
oil mist, or other residue.
Check all wiring connections occasionally for oxidation or corrosion. Clean and re-
seat if such conditions are noted.
If necessary, check and re-seat any connections that may have been subjected to
strain (during rework or construction, for example).
REPLACING BATTERY
NOTE: The QSI2 and QSI3 communications module has a 3V lithium coin cell
battery installed on the PC board. In case of power failure, the battery functions
as power backup to maintain the internal system time. Any QSI2 or QSI3 feature
that uses a time reference as part of its functionality will be immediately accurate
to the current time when power is restored.
•DISCONNECT POWER TO METER
•Remove (6) screws retaining the cover plate to the base and lift the cover plate
free of the meter body (see Figure 9).
•Flip the cover plate over and remove (4) screws retaining the PC board
assembly (see Figure 10).
•Remove and replace the coin cell battery (CR2032) on the backside of PC
board (see Figure 11).
•Reverse the procedure to reassemble the cover plate to the base. Make sure
the cover plate seal is seated before tightening the (6) cover plate screws.
