4.12.6. Low flow rate cutting
Description
 The output can be cut when the flow rate is too small.
 Effective for indication, analog output (4-20mA) and total operation.
Settable range: 0 to 5 [m/s] in terms of flow velocity.
(Factory set: 0.150 [m
3
/h])
Note 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.
Note 2) The flow rate unit is as selected by "FLOW UNIT" in "MEASURE SETUP".
(See section 4.11.2.)
Channel designation : CH1, CH2
* When using 2-pipe measurement, configure both CH1 and CH2.
* No channel setting is necessary for 1-path/energy measurement and 2-path
measurement.
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.5.1.)
Operation
(example) Set the low flow rate cut point to 0.5 [m
3
/h].
* Below is an example for 1-path/energy measurement and 2-path measurement. Refer to Section 4.8.1 for channel
designation of 2-pipe measurement.
