Tank Id is not used so you can leave it at value zero.
Status
The status of a tank is determined by its main state, sub-state flags, and alarm flags. You can assign any state to any tank as needed.
Alarm values are set as percentages. For product alarms, these percentages are calculated based on the Gross Standard Volume relative to the Maximum Fill Capacity. For water alarms, the percentages reflect the water level in relation to the tank's height. HIGH_LEVEL = 0.95, HIGH_HIGH_LEVEL = 0.98, LOW_LEVEL = 0.06, LOW_LOW_LEVEL = 0.05, HIGH_WATER = 0.01.
Data Items
You can only update the values in bold; all other values are calculated automatically. The calculations use the density and volume temperature coefficient for the specific grade stored in the tank, along with the tank's height and shell capacity. These factors together define a hypothetical perfect cylinder that represents the tank's geometry.
Tank parameters
Tank height is the only parameter that can be updated. Tank height and shell capacity together define a hypothetical perfect cylinder, which was used to automatically calculate the table of volumes at different fulfillment percentages.
