This document discusses the calibration of LPG mounded bullet storage tanks. Calibration is defined as determining a tank's capacity and measurement accuracy by recording the volume at various liquid levels. It can be done via dry or wet methods for above-ground or underground cylindrical tanks. Calibrating LPG mounded bullets involves measuring the internal and external volumes, determining the volume based on liquid levels, and ensuring integrated measurement with level instruments. The process features high accuracy inventory monitoring of storage tanks.

1. Calibration of LPG Mounded Bullet
Calibration Defined as the process of exactly determining the capacity or limited capacities of a tank
and stating this capacity as a volume for a given linear increment or height of liquid. Calibration is
basically determining the measurement accuracy of the storage tank on the terminal block. All
instruments used to calibrate equipment should be accurate; the composition and concentration of
any gas samples used for calibration should be accurately known. Calibration should be recorded on
or near the equipment.
Calibration of LPG Mounded Bullet : For CalibratIon of above Ground, Mounded or Underground
Cylindrical tanks either “ Dry method “ or “ Wet method “ is used . The readings of volume obtained
for various heights of liquid levels inside the tank is recorded and the chart is fed into the software of
a computer or HART or Scada system or Tank Inventroy measurement system and the level readings
measured by precise equipmnets like Radar gauges , Servo gauges etc is converted to volume/ mass
