Description
Example of Setup or Remarks
Meter factor
F
Depends on the
specification.
1.0000-2
・Meter factor
(Unit: [□/Pulse])
・Setting range:
0.9999-9 to 9.9999E7
Ex.: Given meter factor 9.918L/P.
To change the indicated flowrate to
read in [m
3
]
→ If hardware scaler DIV switch is
set at 1/10, then
F ＝ 9.9180×10
－3
[m
3
/P]
Hardware scaling (1/10)
＝9.9180×10
－2
[m
3
/P]
Therefore, set to “F9.9180-2” (m
3
/P)
(Note 1)
Conversion
factor
H
1.0000E0
1.0000E0
・Unit conversion factor
(Unit: [Δ/L])
Δ: Unit after conversion
(without conversion
Δ:＝□)
・Setting range:
0.9999 to 99.9999E7
To change units of total flow and
instant. flowrate to any units desired.
(If conversion is not desired, then
H1.0000E0)
Ex.: At 1.5kg per 1L, change the flowrate
to read in kg.
→ Conversion factor is
1.5 [kg/L](＝1.5000×10
－0
[kg/L]).
Therefore, set to “H1.5000E0” (kg/L).
(Notes 2 and 3)
Pulse weight
Pu
Depends on the
specification.
1.00E0
・Weight of factored pulse
output (Unit: [Δ/Pulse])
・Setting range:
0.99-9 to 9.99E7
An invalid parameter in this instrument.
Do not change the setting.
Indicated
unit of
registration

L
・(Unit indicated below LCD) Choose one from “L, kL, m

, g, kg, t,
(normal), and none. (This setting process
only changes indicated unit; It by no
means changes calculation process.
Decimal
point in inst.
flowrate
bP
Depends on the
specification.
0
・ Decimal point in instant-
aneous flowrate b1
・Setting range: 0, 1, 2
Ex.: To change the indicated resolution in
instant. flowrate from 1L/h to 0.1L/h
(＝one place below decimal point)
→Set to “bP .1.”
Decimal
point in
total flow
SP
Depends on the
specification.
0
・ Decimal point in accum.
total and resettable total
flow
・Setting range: 0, 1, 2, 3
Ex.: To change the indicated resolution
in total flow from 1L to 0.01L
(＝2 places below decimal point)
→Set to “SP .2.”
Sampling
time
At
5
5
・ Upper limit in instantaneous
flowrate sampling
(Unit: [sec])
・Setting range: 1 to 999
If flowrate pulses faril to arrive for a
period At [sec], the instantaneous
flowrate shows 0.
Sample
cycle
number
A
Depends on the
specification.
4
・Count of sampling
・Setting range: 1 to 999
Instantaneous flowrate is determined
by measuring the time for incoming
flowrate pulses A times. If the spread of
instant. flowrate indicated is too great,
selecting a larger A eases the problem.
NOTES: 1. Setting the meter factor (F) includes hardware scaling (DIV switch: 1/1, 1/10, or 1/100).
2. Following a change in conversion factor (H), other parameters, such as pulse weight (Pu) and
indicated unit of measurement (Un), must also be adjusted to match the new unit.
3. Be sure to select a value that meets the requirement F×H
2 ≦Pu≦F×H×10000.
