Flow damp
Time constant of flow metering damping
0.48 to 99.99sec
Low cut
Low-cut value of actual flow
0.0 to 100.0%
Low cut hys
Low-cut hysteresis (Select from the right column.)
A function to provide the low-cut value with 5%
hysteresis
ON, OFF
I.F. suppress
factor
Suppress fluctuation of flow output due to impulse-like noise.
Sets the suppression amount of fluctuation with percent
value to the measuring range.
1 to 100%
Calibration
zero
Zero point constant (Offset amount)
This is a constant value related to the accuracy
of the flowmeter. Do not change.
More than -1000.0 and less than
1000.0

factor
Calibration factor
This is a constant value related to the accuracy
of the flowmeter. Do not change.
0.7000 or more and less than
2.0000
Auto gain
compensation
Automatic compensating function to keep the
amplifier gain constant at all times. (Select from
the right column.)
ON, OFF
Flow direction
Flow direction (Select from the right column.)
Sets "Negative Flow" when the direction of fluid
flow is reversed against the arrow direction (flow
direction) of the sensor.
Positive Flow, Negative Flow
Conversion
factor
Fixed conversion factor
Used as a parameter similar to density.
Multiplied to actual flow to calculate mass flow.
0.2 to 5.0
