Tank calibration & cleaning
Why tanks fail without proper care

Aboveground storage tank deployment
Smartflow tank calibration crew on site
Sludge & Sediment Build-up
Sludge on the tank floor eats volume, blocks dispenser filters and kills pumps.
Water Contamination
Water in the tank breeds microbes, accelerates corrosion and degrades the product.
Inaccurate Calibration Charts
Wrong charts mean wrong dip and ATG readings — and lost deliveries you cannot prove.
Corrosion & Wall Deterioration
An unprotected interior corrodes, and a corroded tank eventually leaks.
ATG Probe Inaccuracies
Debris around the probe distorts level and temperature, so reconciliation stops working.
Calibration services
Certified volumetric calibration
Vertical and horizontal tanks, with certified charts for sign-off.
Vertical Tank Calibration
Certified volumetric calibration of vertical USTs and ASTs.
Horizontal Tank Calibration
Horizontal cylindrical tanks, corrected for tilt, deformation and dip-point variation.
Calibration Chart Generation
Certified strapping tables per dip level, submitted for regulatory sign-off.
ATG Probe Verification
ATG probe readings checked against physical measurement after calibration.
Precision Measurement
Certified dip rods, laser tools and volumetric reference standards, not judgement.

Measurement equipment on site

UST fittings and manifold inspection
Cleaning services
Our 6-step process
The same controlled sequence every time, from isolation to signed certificate.

Man-entry through the tank manhole

Confined space entry
Full HSE protocol on every entry
Safety Assessment & Isolation
Site inspection, atmosphere testing and isolation before anyone goes in.
Product Removal & Slop Handling
Remaining product extracted and segregated to environmental regulations.
Mechanical Cleaning
High-pressure wash with Graco Hydraclean cleaners to lift the sludge.
Sludge Extraction & Disposal
Sludge vacuumed out on Husky air pumps and disposed of through approved channels.
Internal Inspection & Defect Mapping
Walls, floor and fittings inspected; defects recorded and reported.

Key benefits
What calibration recovers
Up to 90% Loss Recovery
Closes the measurement gap that lets delivery losses go unnoticed.
Regulatory Compliance
Compliant certificates protect the operating licence.
Accurate Inventory Data
Correct charts make dip readings, ATG data and reconciliation auditable.
Extended Tank Service Life
Remove the sludge and water and the tank stops corroding from the inside.
Improved Fuel Quality
Clean storage means clean product at the nozzle.
Why choose Smartflow
