[NOTE]
Please read before installation and use
To maintain high accuracy and long life of this meter, it is necessary that the meter
be used within the specified conditions in flow rate, pressure, temperature and
viscosity. These operating conditions are stated on the nameplate of the register.
Confirm the contents of the nameplate thoroughly before installation and operation.
(1) In this register, a magnetic sensor is used to pick up magnetic fields of signaling
magnets embedded in the rotor. For this reason, the FLOWPET should be
installed sufficiently away from sources generating magnetic field. If a magnetic
valve of 10 watts or so is used, separate it at least 10 centimeters from the
flowmeter (varies with operating conditions).
(2) For applications in cold regions, install the meter indoors (boiler room, for
example) to prevent accidents caused by freezing.
①A vertical run is recommended for ease of pipeline drainage. Provide a drain
plug.
②When installing lagging, do not lag the electronic register, strainer cover, and
drain plug. Also, make sure of ready separation of the meter from the piping
assembly. NOTE: Refer to the corresponding sections in the instruction
manual for piping details.
(3) This register operates at the temperature range of -10 to +60゜
C. To ensure its
operation within the specified temperature range, protect the register with a
sunshade or heat shield if exposure to elevated temperatures by direct sunlight,
reflected heat, etc., is expected.
(4) This register is designed for indoor use: install the meter in a location free from
rainwater, oil, or sunlight. If exposure to such environment is unavoidable,
provide appropriate weather protection or sunshade.
All specifications in this startup guide are subject to change without
notice for improvement in performance and product quality.
Electronic Register STARTUP GUIDE
Thank you for choosing the FLOWPET-5G.
・This Startup Guide provides basic information that is
helpful for starting the use of the FLOWPET-5G electronic
register. For detailed explanation of the FLOWPET-5G's
functions and operation instructions, refer to the accompa-
nying instruction manual before use.
・Please keep this Startup Guide handy for quick reference.
１．GENERAL SPECIFICATIONS
Display angle adjustable in 15°steps
(Adjust the angle up or down by hand to find
easy-to-view position)
３．BASIC OPERATION PROCEDURE (MEASURE MODE)
The flow indicator at the bottom of the display indicates % of actual flow
(instantaneous flow rate) to the full scale flow rate.
NOTE: Full scale flow rate (flow rate which represents 100%) is determined in
the parameter: AF. (AF value is also applied to the analog output full scale value
of analog output specification)
On the resettable total display,
zero-reset will be performed on
total flow by pressing the RESET
button.
When the MODE button is
pressed:
⇒8 bars appear.
When the MODE button is
kept pressed down:
⇒Bars begin to disappear
one by one from the left
⇒Immediately turning OFF
(letting go of the button)
scrolls the display to the
next one.
２．OPERATION BUTTONS
・The push buttons for operation (MODE and RESET) are located
on the back of the display.

4 to 20mA Analog output
※1： SIG.1 and SIG.2 can generate pulses by built-in battery power without external power source.(Battery life is 8 years approximately.)
For analog output only model, leave the ends of SIG.1 and SIG.2 cables open since they will not be used. Alarm output is optional.

operations are enabled in the Write Mode:
①Pressing the MODE switch moves the digit one place to the left.
②Pressing the RESET switch increases the figure by one.
③Holding the MODE switch pressed for more than 2 seconds again
changes the mode back to the Review Mode.

All parameters are set before shipment based on the
specifications at the time of order receipt, and generally
there is no need for the users to perform parameter
setting. Proper flow measurement may be unavailable if
parameter setting is performed inappropriately. Please
avoid performing unnecessary changes to the param-
eters. (Confirm the corresponding sections in the instruc-
tion manual thoroughly in case it is necessary to make
parameter changes.)
