Terms and Definitions
Following are basic terms and definitions you will need to know in order program and operate the FEM-
3 Flow Monitor.
Engineering unit a unit of measure, such as l iter, cubic centimeter, gallon, ounce, gram, kilogram,
pound, rpm, or Hz.
K-factor (KFR) is a scaling factor based on the average number of transducer pulses per engineering
unit; used to determine rate
Gate time update time interval for display and analog output (.01 to 600 seconds) based on the
number counted during a prescribed time period
Rate Pulse update time interval for the display and analog output based on the time from pulse
edge to pulse edge
KFT scaling of total in engineering units
FEM-03 Start-Up Display Messages
The FEM-03 displays an initial window at power up. After 2 seconds, the FEM-03 displays the following
message for approximately 4 seconds:
LOAD VARS Indicates the device is recalling variables from EEPROM (electrically erasable
programmable read-only memory)
TURN ON Increments each time the FEM-03 powers up
MEM LEFT Displays percent of memory life remaining (.1% increments † )
VERSION Indicates the software version installed in the FEM-03
After this display, the FEM-03 reverts to the last active Display Mode.
†
The FEM-03 stores variables and totalizer values in EEPROM. Minimum EEPROM life is five years with continuous
use. Memory IC can be replaced on-site.
