If temperature volume compensation is being used for
deliveries, the type of temperature volume compensation
must be selected for the Product #. It is necessary
to make a selection for proper Net (temperature
compensated) calculations.
Move pointer to
Comp Type and press ENTER to open
a list box window with the following options:
None
Linear F
Linear C
Table 24
Table 54
Table 6B
Table 54B
Table 54C
Table 54D
NH3
Move pointer to desired option and press ENTER to
accept.
NOTE: If None is selected, deliveries can only be made
in gross (non-compensated) quantities.
Refer to
Compensation Types and Parameters table on
page 39 to assist in making the correct selection.
Comp Parameter is the coefficient of expansion per
degree, the base temperature density, the API gravity,
or the base temperature specific gravity that will be used
with the Comp Type selected. Press ENTER to open a
field edit window and enter a value based on the following
guideline:
Selection Range
None 0.0
Linear F 0.0000 to 0.0025 (per °F)
Linear C 0.000 to 0.005 (per °C)
Table 24 0.500 to 0.550 (SGU)
Table 54 0.500 to 0.600 (KG/Litre)
Table 6B 0.0 to 85.0 (°API)
Table 54B 653.0 to 1075.0 (KG/M³)
Table 54C 0.000486 to 0.001674 (per °C)
Table 54D 800.0 to 1164.0 (°API)
NH3 N/A
If Comp Type selection is either Linear C, or Linear F,
then Base Temp is used to set the base temperature for
temperature compensated deliveries.
If
Linear C is selected for Comp Type, the Base Temp
value will default to 15.0 (for 15 °C). If Comp Type is
set to Linear F, the Base Temp default value is 60.0 (for
60°F).
To change this value, press
ENTER to open a field edit
window and enter a number in this field based on the
following guideline:
Selection Range
Linear F -130.0 to 212.0
Linear C -90.0 to 100.0
S1 Close represents the number of measurement units
remaining on a preset delivery before the valve is placed
in a bypass, trickle, or dwell mode. This field is only used
when a two-stage valve is used in the application and
is connected to the LectroCount register. An S1 Close
value must be set for each product if presetting is being
employed.
When the
S1 Close value is reached, Solenoid 1 is
deactivated and Solenoid 2 is activated.
For example: If value entered is 10 and the preset delivery
is set to 100, then S1 will close and S2 will open when the
register reaches 90. This reduces the delivery flow rate,
slowing down the flow of product through the meter.
Press
ENTER to open field edit window and enter a value
between 0.0 and 99999.0. It is recommended not to use
a value smaller than 10% of preset volume.
