III-2-2. Main Unit
[Main Unit]
Analog
output
St’d/option Standard
Output Instantaneous flow rate
Number of outputs: 2
Output pattern:
1 system parallel output, 8 types
2 system output, 10 types
Special output, 1 type
Note:
1) Instantaneous flow rate will change to velocity value in case of velocity
mode.
2) Ch2 output will be the same type as ch1 output when 1 system or special
output is selected. (parallel output)
Output format 4 - 20mA (1 system / 2 system output)
0.8 - 20mA (special output)
20.8mA
(Burnout when no echo received or during failure warning (span +5%) output possible)
Max. allowable load resistance 1 K ohm, insulated outputs
Terminal panel Screw less Terminal (0.08~2.5mm
2
cable applicable)
Contact
point output
St’d/option Standard
Output For each of the 4 contact points, output selection allocation as
follows. (parallel output possible)
1. Forward flow totalized pulse
2. Backward flow totalized pulse
3. No echo received warning
4. Equipment failure warning
5. Equipment failure or no echo received warning
6. Upper limit warning
7. Lower limit warning
8. Forward flow detection
9. Backward flow detection
10. High range detection
11. Low range detection
12. Not used
Note:
1) Pulse width of contact is selectable from 1000,500,100 or 20ms. But not
for both forward and backward.
2) Each default setting is "ON" at work, but "OFF at work is also selectable.
