All Tank Calibration work including calculation and chart production is performed in-house. HMT can customize calibration charts to meet unique needs of customers including: innage or ullage, feet and inches, decimal feet, or metric units. Our internal checks and balance procedures ensure that all measurements and computations are in accordance with the noted standards.
HMT’s calibration department is well known in the industry and is managed by a team with over 50 years combined tank calibration experience. HMT’s calibration technicians are trained and approved to perform calibration in accordance with MPMS Chapter 2.2 “TANK CALIBRATION”.
Calibration of storage tanks should be performed if the tank is newly constructed, has had structural modifications, is in conjunction with API 653 Inspections, or is during minimum 15 year intervals as recommended by API. Additionally re-computations of calibration charts may be required if there have been changes in products stored that have different gravities, change in floating roof weights or leg positions or if there is a reference gauge height variation.
