FP90 Series Flow Transmitter Instructions
CALIBRATE and OPTIONS menus
The following pages contain the CALIBRATE and OPTIONS menus for each version of the FP90 Flow Transmitter. Be sure you are
using the correct menu:
•
FP90-1: Single-channel Loop Flow Transmitter with one open-collector output
•
FP90-2: Single-channel Loop Flow Transmitter with 2 SPDT relays
•
FP90-3: Dual-channel Loop Flow Transmitter with two open-collector outputs
The rst two characters set the Flow Rate units of measure. They have no effect on calculations. They
may be any alpha or numeric character, upper or lower case.
The last character sets the Flow rate Timebase. Select S (seconds), M (minutes), H (hours) or D
(days).
This setting tells the transmitter how to convert the input frequency from the ow sensor into a 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)
This setting identi 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.
This setting tells the transmitter how to convert the input frequency from the 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. (The K-factor cannot be set to 0)
Select the minimum and maximum values for the 4-20 mA Current loop output. The FP90 will allow any
values from 0.0000 to 99999.
Select the desired mode of operation for the Open Collector output. Options available are High, Low,
volumetric Pulse, or Frequency. The signal may be disabled if not used.
In Low or High Mode, the Open Collector output will be deactivated when the Flow rate reaches this
value. Be sure to modify this setting if you change the Flow Units.
The Open Collector output will be deactivated at Setpoint ± Hysteresis, depending on High or Low
Setpoint selection. (See details on page 6.)
In Pulse mode, the Open collector output will generate one pulse when this volume of ow passes the
sensor. The measurement is based on the Total K-factor. The FP90 will allow any value from 0.0000 to
99999.
In Pulse mode, this setting de nes the duration of the Open Collector output pulse. The FP90 allows
any value from 0.1 seconds to 999.9 seconds.
In Frequency mode, the Open Collector output will simulate the sensor frequency, divided by this
setting. The FP90 allows any value from ÷1 to ÷254.
Use this “note pad” to record important dates, such as annual recerti cation or scheduled maintenance.
