6. INTERNAL COMPONENTS AND FUNCTIONS
6.1 Front Panel
6.1.1 Display
The display is a 8
×
8-dot multiple function display capable of showing the data, units of measure,
error messages, and other information at the same time. (The display is backlighted.)
6.1.2 On-Screen Menu Items
The units of measurement vary with configuration. Their selection is made in the SET mode. Available
menu items are:
() Uncorrected total flow (TOTAL COUNT(Q))
Incoming flow pulses corrected for viscosity are integrated before correction for temperature, and the
obtained totalized flow is indicated. Resolution, or the minimum unit of measurement, which varies
with customer specifications, is set up with front-panel keys. This unit automatically becomes identical
with the output pulse unit.
While the total flow is retained irrespective of power cycling, it is resettable to zero following a power
cycle if so configured in the SYS mode.
() Total flow corrected for viscosity (TOTAL COUNT (Q
μ
f
))
The reading corrected for viscosity is integrated and indicated.
() Total flow corrected for viscosity and temperature (TOTAL COUNT (Q
μ
f
ρ
))
The reading corrected for viscosity and temperature is integrated and indicated.
() Temperature (TEMPERATURE)
The temperature value currently fed to the instrument is indicated to the second decimal place. If a
problem arises in the course of temperature conversion, such as out-of-scale, a default fallback value
is indicated.
(5) Set density (SET DENSITY(
ρ
))
Density value set up in the SET mode is indicated.
() Set viscosity (SET VISCOSITY(
μ
))
Viscosity value set up in the SET mode is indicated.
() Overall error (OVERALL ERROR)
Correction factor to correct for viscosity and temperature is indicated.
[Overall error] = E
×
E
where E
: Viscosity and flow velocity related meter error correction factor
E
: Flowmeter body's volumetric expansion (
α
) related meter error correction factor
(8) Volumetric conversion factor (VCF)
Volumetric conversion factor which is dependent on input temperature and set density is indicated.
The oil kind currently selected is indicated in the field labeled measurement unit.
() Flow velocity and viscosity related meter error correction factor (E
)
Meter error correction factor which are dependent on flow velocity and viscosity is indicated.
(0)
α
correction factor (E
)
Meter error correction factor which is dependent on flowmeter body's volumetric expansion (
α
)
is indicated.
() Pulse input frequenc (FREQUENCY)
Pulse frequency arriving from the flowmeter is indicated.
