Section 4. Configuration
9. Configure the Verification Pin.
In the LPG Setup window click the Config Pins button to open the
LPG Configure Pins window:
Enter the position of the Verification Pin. The position is measured from
the Gauge Reference Point to the actual position of the Verification Pin.
Since hand dipping can not be performed in high pressurized tanks,
Emerson Process Management / Rosemount Tank Gauging has
developed a unique method to verify level gauging in such tanks. The
method is based on measurements in a special radar wave propagation
mode against a fixed Verification Pin in order to verify the measurement.
NOTE!
The value entered in the Nominal Pos field refers to the mechanical distance
from the Gauge Reference Point to the actual Verification Pin. This value will
only act as a starting point for the verification process in which the electrical
distance from the Gauge Reference Point to the Verification Pin is calculated.
In most cases the electrical distance deviates from the actual mechanical
distance.
