Current output
It is recommended that the setting of the flow meter be carried out before installation.
Current output [F15]
One of three output forms of instantaneous flow-rate, pressure and temperature can be
selected for the current output to suit your usage.
When the instantaneous flow-rate is selected, electric current corresponding to the setting of
the maximum flow-rate value of the analog output is outputted.
When the pressure is selected, 4 mA is outputted at the atmospheric pressure, and 20 mA is
outputted at 1 MPa.
When the temperature is selected, 4 mA is outputted at -10C, and 20 mA is outputted at
+60C.
Maximum flow-rate value of the analog current output (Analog output FS flow-rate) [F2]
When the analog output is used by setting to the instantaneous flow-rate, it is recommended
that full scale flow-rate (FS flow-rate) of the analog current output be set with a value
corresponding to maximum flow-rate used.
It is recommended that a numerical value having a margin be set as a set value of the FS
flow-rate.
(Setting example of the FS flow-rate: A set value at the time of nominal diameter 50mm,
flow-rate conversion "With(ON)", room temperature (30°C), pressure 0.7 MPa, flow speed
