Fiscal Metering

Loading a crude oil tanker easily amounts to a transfer value of over $1,000,000 US/hr. Consequently, an uncertainty of only ±0.1% reaches a value of up to $1,000 US for every hour pumped. The new generation Promass Coriolis mass flow meter, proved on the SPSE (Société du Pipeline Sud Européen) calibration rig, has an uncertainty of better than ±0.1%. As you can see, there is huge potential for your company to increase revenue for the same amount of crude sold, by reducing the uncertainty by only 0.1%.

Common standard technologies are used to measure tank inventory manually with measuring tape or by using precise level measurement with mechanical float and tape or highly accurate radar or servo technology. However, to reach standard volume or even to easily compare mass figures, temperature, crude oil density, strapping tables, expansion functions and more should also be considered. A tank gauging system together with a mass flow meter allows you to manage and optimize your inventory.

Today, Promass F mass flow meter directly measures mass flow in tons/hr. Multiplied only by measured density, Promass outputs gross volume in BOPD or m³/hr. Furthermore, the measured density from Promass can be converted to standard density using today's flow computers, providing standard volume as well.

As a complete metering system, e.g. for custody transfer, packaged solutions from Endress+Hauser include flow meters, temperature and pressure transmitters, flow computer and printer and system integration.

With the new development of the large size Promass F, Endress+Hauser mass flow meters are now available for you with a calibration certificate based on various crudes and refined oils ranging from 0.7 cSt. to 300 cSt. Based on this feature, Endress+Hauser customers achieve a new level of transfer accuracies at the point of loading and unloading. Furthermore, a flow metering station based on the Promass involves absolutely no moving parts. Integrated advanced diagnostics allow constant monitoring of the long-term stability of the meter. For this reason, no proving station is required. Proven performance allows for batch uncertainties of better than ±0.1%, according to OIML R117, class 0.3. Remember how much money that means for every 24 hrs pumping?
