Description
Flow1 Units:
GPM >
The fi rst three characters set the Flow Rate units of measure and have no effect on
calculations. They may be any character, upper or lower case. The last character sets the
Flow rate Timebase. Select S (seconds), M (minutes), H (hours) or D (days)
Flow1 K-Factor:
60.000
This setting converts the input frequency from the fl ow sensor into a fl ow rate. The K-Factor
is unique to the sensor model and to the pipe size and schedule. Refer to data in the sensor
manual for the correct value. Limits: 0.0001 to 99999. (The K-factor cannot be set to 0.)
Total1 Units:
Gallons
This setting identifi es the Totalizer units. It has no effect on any calculation. It serves as a label
only. Each character can be any alpha or numeric selection, upper or lower case.
Total1 K-Factor
60.000 >
This setting converts the input frequency from the fl ow sensor into a volumetric total. It also is
used as the basis for the Open Collector pulse mode. The setting is usually the same as the
Flow K-Factor, or different by x10 or x100. Limits: 0.0001 to 99999. (Cannot be set to 0.)
Loop1 Source:
Flow1 >
Select the input source to be associated with Loop output #1:
Flow sensor #1, Flow sensor #2, or Delta Flow.
Loop1 Range: GPM
000.00 → 100.00 >
Select the minimum and maximum values for the Current loop output #1.
The 8550 will allow any values from 0.0000 to 99999
Output1 Source:
Flow1 >
Select the desired mode of operation for the Open Collector output. Options available are
Flow sensor #1, Flow sensor #2, or Delta Flow.
Output1 Mode:
Low >
Select the desired mode of operation for the Open Collector output #1. Options available are
High, Low, volumetric Pulse, or Frequency. The signal may be disabled (Off) if not used.
Output1 Setpnt:
10.0 GPM >
In Low or High Mode, the Open Collector output #1 will be activated when the Flow rate
reaches this value. Be sure to modify this setting if you change the Flow Units.
Output1 Hys:
5.0 GPM >
The Open Collector output will be deactivated at Setpoint ± Hysteresis, depending on High or
Low Setpoint selection. (See details on page 4.)
Output1 Volume:
100.00 Gallons >
In Pulse mode, the Open collector output #1 will generate one pulse when this volume of fl ow
passes the sensor. The measurement is based on the Total K-Factor. The 8550 will allow any
value from 0.0001 to 99999.
Output PlsWdth:
0.1 Seconds >
In Pulse mode, this setting defi nes the duration of the Open Collector output pulse. The 8550
allows any value from 0.1 seconds to 999.9 seconds.
Output1 Freq.:
Divide by 1 >
In Frequency mode, the Open Collector output will simulate the sensor frequency, divided by
this setting. Set for 1 (input frequency = output frequency). Set for even numbers
(2, 4, 6, 8 . . . 254 max) to scale output frequency.
