What is Tank & Vat Calibration?
Tank and Vat Calibration is the process of accurately determining the volume of liquid a storage tank, vat, or container can hold at various levels. This is essential for industries such as oil and gas, chemicals, food and beverage, and agriculture where precise volume measurements are critical. For trade purposes, these vessels must also meet legal metrology and trade approval standards to ensure fair and transparent transactions.
Why is Tank & Vat Calibration Important?
Tank And Vat Calibration is vital when liquids are bought or sold by volume (e.g., fuel, alcohol, milk, chemicals), trade-approved tank and vat calibration ensures that both the seller and buyer receive accurate, legally verified measurements. This protects consumers, maintains market trust, and ensures compliance with national or international regulations such as Weights and Measures Acts or OIML standards.
- Legally verified volume measurements for commercial transactions
- Compliance with regulatory standards (e.g., NMI, OIML, ISO)
- Improved inventory control and loss prevention
- Accurate liquid stock management
- Reduced disputes and enhanced customer trust
What Equipment Needs Tank & Vat Calibration?
Tanks And Vats Calibration is needed across a wide variety of instruments, such as:
- Above-ground and Underground Storage Tanks
- Road Tanker and Rail Tanker Compartments
- Process Tanks and Silos
- Milk and Beverage Vats
- Fuel and Chemical Storage Vessels
Who Needs Tank & Vat Calibration?
Tank and Vat Calibration is essential for any business that stores, processes, or trades liquid products by volume. Industries that require tank calibration include:
- Oil and fuel distribution companies – For accurate fuel volume delivery and trade compliance
- Food and beverage manufacturers – For volume consistency in vats, silos, and fermentation tanks
- Chemical and pharmaceutical plants – To ensure correct batch volumes and safety
- Breweries and distilleries – For legal-for-trade and production accuracy
- Water treatment and utilities – For flow and volume monitoring
- Agricultural and fertiliser suppliers – For liquid feed, additives, and tank storage
- Transport and logistics companies – Where tanker compartments require calibration for trade
If you use storage tanks, vats, IBCs, or road tankers to measure or sell liquid by volume, calibration is legally required to ensure accurate, trade-approved measurements.
How Often Should It Be Calibrated?
Calibration frequency is influenced by:
- Trade regulations (e.g., Weights & Measures Act, OIML R117)
- Frequency of use
- Risk of mechanical wear, movement, or contamination
Typical guidelines:
- Every 12 months for trade-approved tanks
- After tank modifications, cleaning, or relocation
- Before inspections or trade audits
- When measurement discrepancies are noticed
Your regulatory body or quality system (e.g., ISO, GMP, or HMRC Excise) may specify required intervals.
