Setting The Low Flow Rate Cutting - Fuji Electric FLR-3 Instruction Manual

4.9.6. Setting the 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
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 4.8.2.)
For actual keying, refer to the typical operation indicated below. Set the protection to
OFF beforehand. (See Section 4.4.1.)
Operation Set the low flow rate cut point to 0.5 [m
