Volume Correction Factor Calculation Error Status
This value can only be read. If there is no error performing
the volume correction factor then the value is zero otherwise,
the value is a non-zero code and one of the following:
1 = Invalid API value or invalid temperature input value for
6A or 6B VCF calculation.
2 = Invalid API value or invalid temperature input range for
6A VCF calculation.
3 = Invalid API value or invalid temperature input range for
6B VCF calculation.
4 = Invalid API value or invalid temperature input value for
6C VCF calculation.
5 = Invalid API value or invalid temperature range for 6C
VCF calculation.
6 = Invalid API value or invalid temperature range for 6C
Wide VCF calculation.
7 = Invalid delta temperature for 6C VCF calculation.
8 = Interpolation error, temperature value not found in the
table.
9 = Invalid or No VCF method selected.
21.
Volume Calculation Error Status
This value can only be read. If there is no error performing the
volume calculations then the value is zero otherwise the value
Is a non-zero code and one of the following:
1 = Negative table entries are not allowed.
2 = Interpolation error, level value not found in the table.
3 = Sphere Calculation error, level exceeds sphere
radius x 2.
4 = Calculated a negative volume value.
22.
Undefined or reserved registers within the register map
will
return a maximum negative value (8000H, or 80000000H for
register pairs). Attempting to read registers outside the
register map (35198 or higher) will cause a Modbus Exception
Error Code 02 (Illegal Data Value) to be returned.
23.
Temperature Units
The value for temperature units can be one of the following
codes:
0 = Celsius
1 = Fahrenheit
24.
Density Units High
The value for density units can be one of the following codes:
0 = Grams/Milliliters
1 = Grams/Liter
2 = Kilograms/Cubic Meters
3 = Kilograms/Liter
4 = Pounds/Cubic Inch
5 = Pounds/Cubic Foot
6 = Pounds/Gallon
7 = Tonnes/Cubic Meter
8 = Tons/Cubic Yard
25.
Volume Units
The value for volume units can be one of the following codes:
0 = Liters
1 = Cubic Millimeters
2 = Cubic Meters
3 = Cubic Inches
4 = Cubic Feet
5 = Gallons
6 = Barrels
26.
Length Units
The value for length units can be one of the following codes:
0 = Millimeters
1 = Centimeters
2 = Meters
3 = Kilometers
4 = Inches
5 = Feet
6 = Yards
27.
Mass Units
The value for mass units can be one of the following codes:
0 = Kilograms
1 = Grams
2 = Ounces
3 = Pounds
4 = Tons
5 = Tonnes
28.
Set New Device Address
This register will program the new device address. Valid values
for Modbus are between: 1 – 247.
29.
Alarm Units
This register programs the unit type for which you can
configure alarms. Product and Interface can be ‘Volume or
‘Length’ unit type, however Roof can only be ‘Length’ unit
type.
Valid Values are as follows:
2 = Volume Units Type.
3 = Length Units Type.
