Power source (※2)
Battery pack or external power source
Battery pack Lithium battery: 3.6VDC 5400mAh Battery life: 8 years (varies with operating conditions) Storage life: 10 years
External
power source 12 to 50VDC±10% Pulse output : Current capacity 10mA or more
Analog output : Current capacity 30mA or more
Ambient temperature range -10 to +60℃ (no condensing)
Material Polycarbonate (black)
Conguration IP65 (Install under the eaves)
※1: Adjustable with button operation within the range of 1 to 999ms in 1ms increments. Shown above are default settings.
※2: Display functions and pulse output functions can be used just with the dedicated battery pack without an external power source.
(With an external power source, there is no need to worry about the battery life. The power will be automatically switched to battery power in case of power shut-down.)
An external power source is necessary for analog output.
Selectable with MODE switch
■ GENERAL
FLOWPET-5GisanOVALowmeterprimarilyintendedfor
use in boiler feed water and fuel oil metering applications.
Field proven accuracy and long life along with the best price/
performance and ease of use make this industrial meter ideal
as a dedicated tool for heat control.
■FEATURES
1. Available in two product families - for water service and fuel
oil service.
2.Newlydesignedelectronicregistershowstotalowand
 instantaneousowonadigitalLCDatthetouchofmode
select switch. The display angle can be adjusted for better
visibility (Adjustable range: 75 degrees upward, 75 degrees
downward).
3. The electronic register equipped models have an internal battery
(good for 8 years); eliminates the need for an external power
source. (Operation on external power source is recommended for
the pulse output models.)
4. Improved display capabilities compared to the previous EG
register.
 ・LCDcharacterheightincreasedto14mmfrom10mm
 ・Flow indicator allows user to intuitively check

■ WIRING DIAGRAM
■ REMOTE FLOW MEASUREMENT WITH FLOWPET-5G
The FLOWPET-5G with external output capability allows the operator to control water or oil supply from a remote location.
◆The pulse signal generated from an electronic register equipped FLOWPET-5G is of open drain pulse (equivalent of open collector)
both for total counter and ow indicator.
◆For detailed specications of converters and receiving instruments, see respective general specications separately prepared.
■ ALARM OUTPUT SPECIFICATION (OPTIONAL)
Alarm output setting is available as an option.
→The following 3 combinations are available for output assignment as factory setting.

■ OPERATING PRECAUTIONS
To derive maximum benet and safety of operation from the FLOWPET-5G, we recommend that the following
precautions be taken:
1.Fromtheowrangesandoperatingrangesoftheowmeter,strainerandotheravailabledata,selecttherightpumpandvalve
 locationtoensurethattherequiredowrate,pressureandotherfactorsbemaintainedandthatexcessiveowrates,pressure
rises or other damaging conditions be prevented.
2. In cold regions, take due precautions against freezing. If thermal insulation on meter body is desired, see the instruction manual
for the meter. The meter body and strainer are not serviceable at subzero temperatures.
3.Locatetheowmeteritselfandsignalcablesufcientlyawayfromsourcesoflargemagneticelds(e.g.,pumps,electric 
motor-driven and solenoid valves). (For example, keep a solenoid valve 10 watts or so in power consumption at least 10
centimeters away.)
4.Acceptableuidsdependonthetypeofowmeter.TheFLOWPET-5Gisprimarilydesignedforboilerfeedwaterandfueloil.
 Ifyouhaveanyotherapplicationinmind,consultournearestsalesofceoragent.
5. Not serviceable for certifying and authenticating legal transactions by the Measurement Law.
6.Thisregisteroperatesoveratemperaturerange-10to+60°C.Inlocationswheretheregisterispotentiallyexposedtoelevated
 temperaturesbydirectsunshine,reectedheat,orotherheatsource,provideanappropriatesunshade.
7.Foroutdoorinstallation,provideaprotectionagainstdewdrops.Usewithinthespeciedtemperaturerange.
8. Install in a location where the register assembly is free from direct exposure to rainwater, oils, chemicals, etc.
9.Thismeterhasnosubtractcountercapability.Ifpulsation(uctuationofowrateduetotheeffectofpressurechange)or 
 reverseowoftheuidowoccurswithinthepipeline,thetotalowreadingmaybeinconsistent.
