Low flow rate cut setting value
4.5.3. Setting the low flow rate cutting
Description
z
The output can be cut when the flow rate is too low.
z Effective for indication, analog output (4-20 mA) and total
operation.
Settable range: 0 to 5 [m/s] in terms of flow velocity
(factory set at 0.150 [m 3 /h]).
Notes
1. As required, set the low flow rate cut because the flow meter
may read a flow rate when the fluid in the piping is moving
on account of convection, etc. even if the valves are closed.
2. The flow rate unit is as selected by "FLOW UNIT" in
"MEASURE SETUP" (see Section 4.6.2).
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand
(Section 4.4.1).
Typical operation Set the low flow rate cut point to 0.5 [m 3 /h].
