8550-3 Flow Transmitter
‡ SIGNET
Monitor the flow rate of Channel 1 and Channel 2 simultaneously.
This is the permanent view display.
Monitor the delta flow rate (Channel 1 rate - channel 2 rate = Delta Flow)
This is a permanent display.

3.3 Open Collector Output
The Open collector output can be used as a switch that responds
when the flow rate moves above or below a setpoint, or it can be
used to generate a pulse that is relative to the flow volume or to
the flow rate.
•
Low
Output triggers when the flow rate is less than the setpoint.
The output will relax when the flow rate moves above the setpoint
plus the hysteresis value.
•
High
Output triggers when the flow rate is greater than the setpoint.
The output will relax when the flow rate drops below the setpoint
plus the hysteresis value.
•
Frequency
Output is a pulse stream that is based on the input flow sensor
signal. Set for 1 (input frequency = output frequency). Set for
even numbers (2, 4, 6, 8, . . . . 254 maximum) to scale output
frequency.
•
Pulse
Output is a pulse based on the volume of fluid that passes the
sensor. Set any value from 0.0001 to 99999.
The output may be disabled (Off) if not used.
Monitor channel 1 and channel 2 Resettable Totalizers. Press the RIGHT
ARROW key to reset the totalizer. If Reset is locked, you must enter Key
Code. Lock or Unlock function is in OPTIONS menu.
Monitor channel 1 Permanent Totalizer value.
Monitor channel 2 Permanent Totalizer value.
Monitor the 4-20 mA Loop 1 output.
Monitor the 4-20 mA Loop 2 output.
Monitor date for scheduled maintenance or date of last calibration.
