Accuracy in laboratory is not the
same as accuracy in field


In labb parameters such as temp.
density, pressure are known and
statics. In field compensation must
be made.
Custody Transfer Authorities have
calculation for this:
– Hysteres ± 1mm
– Temp.
± 1mm
– Density ± 0.5mm


A total of ± 3.5 mm with instrument
accuracy
So this is the FIELD ACCURACY

Radars (like most Automatic Tank Gauge) are measuring
Ullage
On an ullage system the level accuracy is influenced by:
Roof movement
Tank Bulging
Thermal expansion of tank wall
Tank settling
These problems can be overcome by:
•Mounting gauge at a stable point, which most often is found close to the tank wall.
•Temperature monitoring, calculating expansion of wall, and compensating for expansion.
•Correction through “Special Correction Table” in the RTG.
•Regular inspection of tank
Level Accuracy depends on the stability on the tank. How much the tank bulges when product is added to the tank.
This will make the Reference height to changes from R1 to Rn.
This can be adjusted by a good accurate hand dipping at several levels.
To correct a measurement error due to tank movement, a Special Correction Table can be added to the RTG.
Before program a SCT into a RTG the error must be confirmed and equal form time to time when
product is added or taken out from the tank.
To monitoring this it needs a good hand dipping record.
NOTE:
Due to the API standard, Hand Dipping accuracy is + 3 mm.

General notes:
- The hand dipped levels record
must each be based on three
independent measurements, no
one deviating more then 1 mm from
each others.
- The tape shall be calibrated within
one year. In good conditions with
out damages, e.g. bends and nicks.
Calibration of RTG:
- Cone and Parabolic Antenna
Gauges: The measurement must
be distributed over at least half of
the Tank Reference Height, R from
bottom.
- Still Pipe Gauge: The
measurement must be distributed
over the complete range of the
tank. At least five of the
measurements should be taken in
the upper quarter of the measuring
range and at least five in the bottom
range.

Tank Verification:
A record is needed over the hole range,
both when filling and when unloading the tank.
