Abstract: Custody Transfer Measurement in the Oil and Gas Business has been described many ways. It has been called An accuracy in measurement, that both the buyers and sellers can agree upon, or The best that can be achieved to meet the contract conditions. But I like to call it The Search for the Truth. Ever since petroleum has been bought and sold, people have searched for better ways to measure on the fly with better accuracies.

If we want to put 0.02% into perspective that is 6.45 Teaspoons or a little more than 2 Tablespoons of oil in one 42 gallon barrel. That is very good measurement and that is worse case. That is why we all strive to exceed the 0.02% required by API. We know and understand the value increased accuracy has to our companies
