Abstract: There is an increased importance being placed on flow metering by industry. With increasing energy costs a flow meter with a set percentage flow rate uncertainty is set to have an increasing monetary uncertainty. There is therefore a demand for reducing the uncertainty of all flow meter designs. In practice, as a flow meter uncertainty rating is only valid if there is a guarantee the meter is operating correctly, this also means there is a growing desire to improve the output verification capabilities and self diagnostics of all flow meter designs. Systems with redundancy factors are also desirable. In this paper the potential for combining vortex shedding and differential pressure (DP) meter technologies is discussed. It will be shown that combining these different technologies in one device produces a single flow metering system with distinct advantages compared to when a vortex shedding flow meter or a DP flow meter stand alone. This simple, sturdy, relatively inexpensive and reliable system meters the mass and volume flow rates as well as measuring the fluid density with no external fluid property information required. It offers enhanced output verification capabilities and allows some diagnostic capabilities.
