3.9.1. Damping
Description
●
Used to reduce fluctuation of measured values.
The setting value is a time constant. (Response time of about 63%.)
Setting range: 0 sec, 1 sec, 3 sec, 5 sec, 10 sec, 30 sec, 60 sec, 90 sec
Note) When the damping setting is set to 0 seconds, the response time is as follows.
• System cycle 0.2 sec
• Elapsed time of 0.2 sec or less; Time constant of 0.1 sec
For specific key operations, refer to the example in
3.9.2. Flow rate unit setting
Description
●
You can set the flow rate unit and total value unit from two different systems of measurement, i.e., the metric and imperial systems.
●
Metric system (factory default) L
When L is set, the flow rate unit becomes L/min.
When L is set, the total value unit becomes L.
For specific key operations, refer to the example in
3.9.3. Low-flow cutoff setting
Description
●
Output can be cut off when the flow rate is low.
●
Enabled for display, analog output (4 to 20 mA), and total value.
Setting range: FSZ08: 0.00 to 99.99 [L/min], (Factory default 0.15 [L/min])
FSZ15: 0.0 to 999.9 [L/min], (Factory default 0.5 [L/min])
FSZ25: 0.0 to 999.9 [L/min], (Factory default 1.5 [L/min])
Note 1) The flowmeter may issue a flow indication when the fluid in the piping is
moving due to convection, even when the valve is closed. Therefore, set the
low-flow cutoff point as necessary.
Note 2) The flow rate unit is the unit selected in "Flow rate unit".

3.9.4. Method for correcting measurement value
Description
●
Used when you want to arbitrarily adjust the measurement value.
Zero point and span adjustments are possible.
Setting range
(1) Zero point: FSZ08: -99.99 to 99.99 [L/min], (Factory default 0.00 [L/min])
FSZ15: -999.9 to 999.9 [L/min], (Factory default 0.0 [L/min])
FSZ25: -999.9 to 999.9 [L/min], (Factory default 0.0 [L/min])
(2) Span:
0.0 to 200.0%
The output value (display value, analog output, and total value output) is calculated using the
following formula.
Measured value × [Span%]
Output =
100
Note 1: The flow rate unit is the unit selected in "Flow rate unit".
