What you need to know
Calibration is the method by which the exact volume of your tank is calculated in line with specified measurement standards. This process is key to obtaining accurate measurements of quantity as it helps in keeping good contractual relationships with your clients, governing bodies and insurance companies.
- We do tank calibration to ensure your tanks have the correct measurements to avoid fuel losses and increase the accuracy of your dipping.
- A well-calibrated tank gauge benefits your business by providing you with accurate stock readings at the end of each day.
- Poorly calibrated tank gauges may result in fuel losses going unnoticed, which could ultimately impact upon the profitability of your business.
Why Should a Tank be Recalibrated at Regular Intervals?
- Imperceptible to the human eye a tank may change its calibration whenever the operating conditions are changed. This could be for a variety of reasons. For example:
Expansion or contraction of tank shells due to hydrostatic liquid head pressure or changes in operating temperature.
- Any modifications to the tank or the dip plate – i.e., new pipe inverts, floor repairs, floating roof modifications, changes in deadwood, etc.
- Changes in tank plate thickness.
- Relocation of the tank.
- Tilt and settlement of the tank with resultant changes in the tank geometry.
- Change of product density – this will affect the expansion characteristics of the tank, hence the volume.
7. It is generally recommended that a tank should be recalibrated at not more than 5 year intervals, especially considering tank settlement. In areas where tank settlement or ground subsidence is known to be a problem, an external settlement survey can be performed which we also specialize.
