External Tank Strapping method (ISO 7505 Part I) and Part II of Nineth Schedule of the Legal Metrology (General) Rules 2011.
Datum plate height with reference to individual course heights.
Determination of Dip-reference height and point of gauging.
Inclination & Spherical dish-end measure of horizontal tanks.
Calibration of pressurized Spherical tanks and horizontal bullets: internal vertical and horizontal diameters, position of magnetic servo float with respect to bottom.
Internal deadwood measurements.
Ultrasonic Plate thickness measurements.
Determination of flush point of bottom of vertical cylindrical tanks by water through flow meter.
Physical calibration of uneven conical or spherical bottom of tanks and spirit vats up to the datum plate of vertical cyl. portion.
Floatation of roof for floating roof tanks by water to determine volume displacement by weight of the roof. This displacement is to be applied for density corrections of liquid stored.
Complete physical calibration is required for deformed underground FRP horizontal tanks which have lost its cylindrical shape, in measured intervals through accurately calibrated flow meter and data recorded for later processing and interpolation of volume into even segments.
