Oval FLOWPET-5G General Specification

■ GENERAL
FLOWPET-5G is an OVAL flowmeter 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 flow and
instantaneous flow 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
instantaneous flow rate
■ Electronic Register Specifications
Item

① Low battery alarm (Low battery indicator "
② LCD with 7-segment, 14mm-high characters (background color: orange)
Function ③ Flow indicator (10-segment)
④ Simulated output: set any accumulated total or instantaneous flow rate for simulated outputs (unfactored, factored, and analog)
⑤ Protection against erroneous wire connection
Register accuracy Total flow: ±1 count, Instantaneous flow rate: within ±1% of full scale
Display orientation 150° range in 15° steps (From horizontal position: upward 75°, downward 75°)

※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.
