APPLICATION: Fuel and fuel additives test system for final testing of gasoline pumps at Parker Hannifin Manufacturing Germany GmbH & Co. KG in Mainz-Kastel. The pumps are used by Formula 1 racing teams. Every single gasoline pump is tested and qualified on the test system under completely different operating parameters before they are delivered to the racing customers.
CHALLENGE: A test system of high technical complexity was being designed and modelled for unlimited final testing of gasoline pumps for Formula 1 racing customers. To meet the very high demands for quality, the test must cover the entire performance spectrum and provide the optimum testing conditions for the final test. In the area of flow measurement, the task was to specify a highly accurate sensor for the most varied operating parameters. The flow conditions comprised a large spread in temperature and process pressure. This resulted in a change in the viscosity of the fuel. In the first design, turbine flow meters and TRICOR Coriolis mass flow meters were considered. The solution with turbine flow meters required a cascading of several devices to cover the required flow measurement range. Furthermore, different calibration curves needed to be used in order to meet the accuracy requirements.
SOLUTION: TRICOR Coriolis mass flow meters, by contrast, provide multiple technical advantages for this test bed. Flow meters using the Coriolis principle are significantly more accurate, faster and are almost completely independent from the medium properties like viscosity, temperature and pressure – in contrast to some other flow meters. The TCM 0650 covers the entire testing measurement range. With the TRICOR Coriolis solution, Parker Hannifin can cover the required temperature and process pressure range on the fuel test bed with one device. There are no restrictions in regards to fluid, viscosity or accuracy of measurement. Additional components for a cascading measurement (such as needed with the turbine flow meter option) and the associated added expense are eliminated.
CUSTOMER ADVANTAGE: All requirements are met by the broad measurement range of a single TCM 0650. It reduces not only the purchasing costs but also the costs for having replacement devices. Using analogue output signals and modbus TRU interfaces, mass flow, volume flow, temperature and medium density can be read out at the same time on the local display – remote optional. The TCM 0650 is the optimal solution for Parker Hannifin in order to master this challenging measuring task.
