Flowrate sensor judgment can be used for slow flowrate stop, dry pump detection and end of
curve detection. The flowrate sensor uses digital signal ON (flowing) and OFF (not flowing)
as detection results. The flowrate sensor can be used for detection with either a digital input or
an analog input. If not set, the flowrate sensor is taken to be OFF.
If the flowrate sensor is set with a digital input, the digital input FS is the flowrate sensor.
If the flowrate sensor is set with an analog input, the results of comparing the analog value
selected for the flowrate sensor (input selection) (J163) and flowrate sensor (ON level) (J164),
(OFF level) (J165) becomes the flowrate sensor.

 Flowrate sensor (ON level) (J164), (OFF level) (J165)
If the flowrate sensor is set with an analog input, the flowrate sensor ON/OFF levels are set. If
the analog input value exceeds the flowrate sensor (ON level) (J164), the flowrate sensor is
recognized as ON. If the analog input value is below that of the flowrate sensor (OFF level)
(J165), the flowrate sensor is recognized as OFF.
- Data setting range: 0.00 to 9990.00, OFF (Setting range is limited by maximum scale and
minimum scale.)
 Flowrate sensor (Input filter) (J166)
Sets the input filter if flowrate switches are connected to terminals X1 to X7. If the flowrate
sensor has an analog input, this filter does not work.
 Please set the flowrate switch FS (data = 131) to function codes E01 to E07.
