When a flow rate is decreasing and an actual flow rate goes below 0.95 [m
3
/h], the output flow
rate is reduced to 0.0 [m
3
/h] with the low-cut function. On the other hand, when a flow rate is
increasing and the actual flow rate goes over 1.05 [m
3
/h], a flow rate is output.

NOTE
Note that the totalization might be counted due to the influence of the output fluctuation near 0%
output if a small low-cut value is set.
In particular, if the value of the flow rate span, damping time constant or conductivity is low, the
totalization is easily counted when the flow rate is zero. In such a case, increase the flow rate
span, damping time constant, or low-cut value.
NOTE
If the output process value to be output is changed, it is necessary to specify the low-cut value
again.
5.1.8 Sensor’s Nominal Size Setting
To combine the remote transmitter with other remote sensor, the nominal size of the remote
sensor must be set.
The setting can be configured with the following parameters.
