- STORAGE TANK CALIBRATION
- STATUTORY OBLIGATION FOR CALIBRATION
- On the above subject Under Section has to say that as per the provision of Section 22/24 of the Standard Weights & Measures (Enforcement) Act 2009 no Weights & Measures shall be sold or offered or possessed for sale or use or kept for use in any transaction or for Industrial Production or Protection unless it has been verified & stamped and as provided in Rule 14 of the Standard Weights & Measures (Enf) Rules 2011 framed under the said Act that Storage tanks including VATs used or intended to be used in any transaction or for Industrial Production or for Industrial Protection shall be re-verified or re-calibrated and Stamped at least once in a five year. The definition of the word "Transaction", provide in Section 2 ( Z ) of the Standard Weights & Measures Act 1976 under which the said Standard Weights & Measures ( Enf.) Act 2009 has been enacted which runs as follows. Any contract for Sale, Purchase, Exchange or any other purpose.
- I. Any assessment of Royalty, Toll or other dues.
- II. II. Any assessment of work done, wages, dues or service rendered, their Storage tank can not be excluded from the purview of the above said Act & Rules.
- • To meet Central Excise / State Excise & Custom Duty obligation in view of the aforesaid it is essential to get rid of any Legal Action as provided in the said Act.
- • Fines & Seizures for noncompliance./li>
- WHY CALIBRATION IS ESSENTIAL:
- To ascertain gain or loss in sale, purchase to provide only reliable means of maintaining adequate control over the Storage & Distribution loss, stock keeping & industrial production process control. As oils, chemicals and its allied products are very costly items business and service renders from it.
- • Profit & Loss depends on accuracy of Storage tank calibration work
- • Settlement of disputes in management, production, purchase / sales cycle.
- So from above it is easily understood that you require our efficient prompt service for your business prospect in new millennium.
- To ascertain gain or loss in sale, purchase to provide only reliable means of maintaining adequate control over the Storage & Distribution loss, stock keeping & industrial production process control. As oils, chemicals and its allied products are very costly items business and service renders from it.

- o No. of joints and its step-over correction
- o Detection of DIP reference height
- o Safe height detection
- II. Bottom Calibration (in side tank work)
- o Fitting water flow meter with water connection and taking reading opening & closing for datum flush
- o Taking datum height
- o Water level at various places in side the tank as when required in calibration process
- o Deadwood correction factor (+ factor and – factor) taking into consideration
- III. For Floating Roof

- PLEASE NOTE: Items Required for Storage Tank Calibration Work
- 1. ARRENGEMENT
- Govt. Statutory Fees & Inspector's Conveyance
- 2. FOR STRAPPING
- Scaffolding:-
For Linear/Non Linear Measurement & Ultrasonic Thickness Test Clean surroundings at tank site etc. - 3. FOR PHYSICAL BOTTOM CALIBRATION
- o WATER/Production connection with hose
- o Pipe/Flange/Fittings/Reducer arrangement for Fitting and Fixation of water/flow meter
- o Manhole opening should be there
- o Clean and clear bottom
- o Lighting arrangement if required
- o Inlet & Outlet should be closed properly
- 4. FLOATING ROOF TANK FOR ROOF FLOATATION
- o Water connection with house
- o Position to fit water meter with connection fittings arrangement for it from your part
- o Tank should be Box up and Manhole fitted
- o Roof at working height (i.e. lower leg position)
- o Staying facilities if required during the time of floatation work
PROCEDURE OF VERTICAL STORAGE TANK CALIBRATION
STEPS FOR CALIBRATION:
- WE PERFORM OUR JOB IN:
- 1. VERTICAL CYLINDRICAL ROOF TANKS
- 2. VERTICAL FLOATING ROOF TANKS
- 3. HORIZONTAL CYLINDRICAL TANKS
- 4. RECTANGULAR TANKS
- 5. BLENDING TANKS
- 6. UNDERGROUND HORIZONTAL TANKS
- 7. BULLETS WITH SPHERICAL ENDS
- 8. HORTON SPHERES
- Application of the most appropriate method and a through understanding of the characteristic and geometry of a particular tank is absolutely essential. Here is where good experience, engineering and mathematical background in indispensible.
- Guidelines are laid down by the Weights & Measures department can be followed to calibrate your tanks.
- Internal inspection is carried out if possible in tanks where it is safe to enter enabling us to measure datum plates and internal deadwood. Underground Horizontal tanks require internal measurements. Bottom plate unevenness is profiled and physical calibration with water is done up to flush point.
- All field data are fed into our computer with specific software for specific linear correction like tape temperature corrections, thickness correction deadwood corrections, etc. and shell wise calculation as per Rules laid down by the Weights & Measures Dept. complex mathematical formulae and calculations are involved in case of Horizontal tanks and spheres where volume increments increase and decrease in a non-linear manner. No averaging process is carried out as is done elsewhere.
- Calibration charts are made in centimeter and litre, to the fraction of the nearest millimeter.
- MEASUREMENTS PROCESS AT SITE ON TANK:
- • External Tank Strapping method and part ii of 9th, Schedule of the Standards of Weights & Measures (General) Rules 1987.
- • 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.
- • Horizontal diameters, position of magnetic servo float with respect to bottom.
- • Ultrasonic plate thickness measure.
- PHYSICAL CALIBRATION PROCESS AT SITE IN TANK:
- 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 cylindrical portion.
- Complete physical calibration is required for deformed underground FRP horizontal tanks 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.
- WE ALSO OFFER SERVICES:
- • Electronic Weighing Scales.
- • Stability Certifica/tes
- • Flow Meter
- • Weigh Bridge
- • Pressure Vessels
- • Dip Rods
- • Temperature Indicators
SCOPE OF WORK:
Our scope of work includes all associated work required for calibration of the tanks including supply of skilled and unskilled labour coordination with the official of Legal Metrology Department, Preparation of computerized calibration chart and obtaining approval, from Legal Metrology (Weights & Measures) Department, Strapping (Linear & Nonlinear Measurement) bottom calibration through flow meter arrangement of measuring instrument, submission of calibration chart with CD for your record, ultrasonic plate thickness measurement with digital meter for all the shell including report as required. We will stay very near your site for smooth running of calibration work. You have to arrange water for calibration work.(Physical calibration only). We will submit approved calibration chart with in very short time and we will submit proforma chart within 48 hours to you part. We assure best service always, if we get said order we will start the work immediately if required, we are looking for a valued work order from your esteemed Company.
OUR PROMISE:With hard earned experience behind us, we would like to enjoy your trust which we promise to meet in a highly responsible manner, at a reasonable price.
