Inspection: It is, most  generally, an organized  examination or formal  evaluation exercise in lines  with some standard  guidelines to determine  the suitability / fitness of a  commodity being involved  in trading by way of  measurements and tests.  The Inspection process  gives confidence to the  end user of the commodity  as well to the supplier. Testing: It is a verification  process to find out the  values of the different  parameters involved to  determine the quality of  the commodity being  traded or used by the  different industries and  the consumer worlds.  Testing process gives the  indication of the suitability  of the commodity for  usage or trading. Calibration: Inspectorate is  specialized in calibration of  Vertical or Horizontal  shore tanks, adopting such  techniques as Laser  Distance and Angles  Technology with precise  accuracy. Laser technology  enables the calibration of  shore tanks without  scaffolding, thereby  avoiding additional cost  and disruption.

(EODR) Electro‐Optical Distance Ranging Method

EODR Methodology ► Measurement of reference circumference by manual strapping method. ► Vertical measurement of tank shell by using electro‐optical distance ranging instrument. ► Bottom measurement by using horizontal auto level or laser level & leveling  staff. ► Accurate measurement of positive, negative deadwoods, reference height & any other accessories that may  affect on tank working height & tank volume. ► Calibration chart calculations & preparation of calibration chart. EODR Advantages ► More safe: The danger of falling from the ladders or Boson chair is eliminated.Vertical measurement of tank  shell by using electro‐optical distance ranging instrument. ► Less Cumbersome: The method eliminates any movement of heavy equipment such as hoists, boson chairs or  ladders.

► More Economical: Less persons are required during conventional strapping & ORLM vis a vis EODR method. ► More Accurate: Cancels out human random errors caused due to fatigue, environmental influences, improper
