A great deal of importance is attributed to the physical measure of flow (ie volume or mass per time unit of a fluid) in the economy of a country, as well as in the international trading of goods, due to the fact that a very large part of raw materials and energy carriers (oil, gas, water, heat carriers, etc) are transported from the producer to the consumer as a liquid or a gas through pipelines.
As inaccuracies of measurement even of just 1% when dealing with large quantities of product can mean profits or losses for either producer or buyer in the region of several million DM, the economic necessity of having measuring equipment capable of measuring with the least possible uncertainty is paramount. This problem is being addressed by using more modern measurement principles, and constant improvement of the equipment parameters, in particular with regard to the reduction of the uncertainty in measurement.
