9.1.5 Level settings (Cont.)
Factory Set:
Method – Enter Level Offset:
a calibration method that directly
changes the offset of the level measurement. The offset is the zero
reference point used in determining the level output. Do not use
without Factory guidance.
Product Offset:
the full length of the level transmitter including order
length, inactive zones, and mounting length. Do not change the Enter
Level Offset method without Factory guidance. The offset will change
after using the Enter Current Tank Level for the Product. The Product
Offset and Interface Offset are independent of one another.
Interface Offset:
the full length of the level transmitter including order
length, inactive zones, and mounting length. Do not change the Enter
Level Offset method without Factory guidance. The offset will change
after using the Enter Current Tank Level for the Interface. The Product
Offset and Interface Offset are independent of one another.
User Configurable:
Length Units:
the unit of measurement used for engineering units.
Default is inches if ordered in inches and mm if ordered in mm.
Options include inches, feet, millimeters, centimeters, and meters.
Method - Enter Current Tank Level:
a calibration method that
calibrates the level transmitter based off of one point of measurement.
Select Enter Current Tank Level from the Method drop down box. Go
to Product Level and enter value of current product level based off of
a manual measurement while the tank level is not changing. Go to
Interface Level and enter value of current interface level based off of
a manual measurement while the tank is not changing. Click Update
box in lower left corner when it appears. Level transmitter is now
calibrated.
Product High Alarm:
Soft alarm that can be disabled or enabled by
clicking the X and √ next to the box. If the product level exceeds the
value in the box then the alarm will become active.
Product Low Alarm:
Soft alarm that can be disabled or enabled by
clicking the X and √ next to the box. If the product level is less than
the value in the box then the alarm will become active.
Interface High Alarm:
Soft alarm that can be disabled or enabled by
clicking the X and √ next to the box. If the interface level exceeds the
value in the box then the alarm will become active.
Interface Low Alarm:
Soft alarm that can be disabled or enabled by
clicking the X and √ next to the box. If the interface level is less than
the value in the box then the alarm will become active.
9.1.6 Temperature settings
Fig. 8: Temperature settings
Factory Set:
Number of Sensors:
Defines how many temperature sensors the level
transmitter is looking for. The number should match the number of
temperature sensors in the model number.
Number of Averages:
This is the number of temperature readings
that are averaged together for the temperature output. The higher the
number the more temperature readings that are averaged. The higher
the number the smoother the output but also the slower the update to
changes in the process temperature.
Position:
The location of the temperature sensor in reference to the
end of the pipe.
Slope:
Calibration factor for the temperature sensor. The defaults
setting is 1.0. Do not change unless a new sensing element with
temperature is ordered.
Intercept:
Calibration factor for the temperature sensor. The default
setting is 0.0. Do not change unless a new sensing element with
temperature is ordered.
User Configurable:
Temperature Units:
Change the units of measure for the temperature
settings. Options are Fahrenheit or Celsius.
Temperature High Alarm:
Soft alarm that can be disabled or enabled
by clicking the X and √ next to the box. If the temperature exceeds the
value in the box then the alarm will become active.
Temperature Low Alarm:
Soft alarm that can be disabled or enabled by
clicking the X and √ next to the box. If the temperature is less than the
value in the box then the alarm will become active.
