Range
• Contact output: For a maximum external load of 30 Vdc/200 mA, indicating any one of the
following condition states:
– Alarm actuating contacts for
Self-diagnosis alarm —Outputs an alarm-actuating contact when the self-diagnosis function
detects an error.
No-load detection alarm (with empty-status detection) —Outputs an alarm-actuating
contact when the fluid level in the detector goes below the electrode level.
Upper/lower flow limit value alarm —Outputs an alarm-actuating contact when the flow
volume exceeds the upper/lower limit values.
Two-stage flow value alarm (with two contact outputs) —Outputs an alarm-actuating contact
when the flow value exceeds the two upper limits (H and HH) or the two lower limits (L and
LL).
– Range identification output—Outputs a contact for large and small ranges, forward and
reverse direction ranges.
– Counter preset status (for pulse output model)—Outputs a contact when the built-in
counter reaches the preset value.
Display Display card can rotate 90° for installation on vertical pipe.
Backlit liquid crystal display (LCD).
Display board: One line with six 7-segmented digits—Main display
Dot matrix, two lines with 16 columns—Auxiliary display
Display contents:
