13. Tank Reference Height (R) is the distance from the Tank Reference
Point to the Zero Level near the tank bottom. Ensure that this number is
as accurate as possible.
14. The Reference Distance (G) is the distance between the Tank
Reference Point and the Gauge Reference Point, which is located at the
upper surface of the nozzle flange or manhole cover on which the gauge
is mounted. G is positive if the Tank Reference Point is located above
the Gauge Reference Point, otherwise G is negative.
15. The Minimum Level Distance (C) is defined as the distance between
the Zero Level (Dipping Datum Point) and the minimum level (tank
bottom) for the product surface. By specifying a C-distance the
measuring range can be extended to the bottom of the tank.
C>0: the 5900S presents negative level values when the product surface
is below the Zero Level.
You can use the Show negative level values as zero check box if you
wish to present product levels below the Zero Level (Datum plate) as
equal to zero.
