9.1.7 Volume settings
Fig. 9: Analog settings
User Configurable:
Volume Units:
allows the user to select the unit of measure for the
volume output. Available options are liters, cubic millimeters, cubic
meters, cubic inches, cubic feet, gallons, and barrels.
Density Units:
allows the user to select the unit of measure for the
density input. Available options are kilograms, grams, ounces, pounds,
ton, and tonnes.
Mass Units:
allows the user to select the unit of measure for the
mass output. Available options are grams per milliliter, grams per liter,
kilograms per cubic meter, kilograms per liter, pounds per cubic inch,
pounds per cubic foot, pounds per gallon, ton per cubic yard, and
tonnes per cubic meter.
Correction Method:
allows the end user to select the temperature
correction method from the available API tables including 6A, 6B, 6C,
6C Mod, and Custom Table. Custom Table allows the end user to enter
up to a 50 point custom temperature correction table.
API Gravity:
allows the end user to enter the API gravity of the liquid as
defined in the glossary. Used for 6A and 6B correction methods.
TEC:
Thermal Expansion Coefficient used for temperature correction.
Allowable values are 270 to 930. TEC units are 10 E-6/Deg F. Used for
6C Mod correction method.
Reference Temp:
allows the user to specify the reference temperature
for 6C Mod correction method.
Density:
allows the user to input the measured density for mass
calculations
Calculation Mode:
allows the end user to select between using a
strapping table and a sphere. Default setting is Sphere.
Working Capacity:
allows the end user to enter the working capacity of
the tank so ullage can be calculated.
Sphere Radius:
the radius of the sphere to be used for volume
calculations.
Sphere Offset:
an offset value that should be added to the volume
calculation of the sphere based on tank geometry.
Entries:
allows the user to select how many strapping tables entry
points to use. Maximum is 200.
Export Table:
allows the user to export the strapping table from the
level transmitter. This should always be done after completing the
strapping table. Save as the site name, tank number, and any other
unique identifier.
Import Table:
allows the user to import the strapping table from a file.
This can be used when replacing electronics or for tanks of the same
size.

Reset to Factory Defaults:
Allows the end user to reset all settings
back to the original settings as they were when they left the MTS
factory. This is intended to be used as a first step in troubleshooting.
Do note, the Zero and Span set points will reset to factory settings.
Fix fault code 128:
