| Zusammenfassung | A new test bench for calibrating flowmeters with hydrocarbons has been set up at the PTB. The measuring range currently covered extends from 0.25 l/h to 100 l/h. Several developments regarding test bench components evolved in the course of setting up and commissioning the metrological infrastructure. E.g., a mass comparator is used as a gravimetric reference, which is tared and checked with a calibration weight before each measurement to monitor the drift. A PTB designed and manufactured diverter is used. The entire test bench is operated in a climate-controlled environment. The measurement uncertainty for volume is typically about 0.01 % (k=2) when HAKU, a cold cleaner, is used as working liquid and at room temperature. The uncertainty increases significantly in the lower measuring range to 0.04 %. Different hydrocarbons can be used as working liquid, provided that occupational safety requirements are met. At present, there are two storage tanks available for hydrocarbon-based test liquids. Regarding further developments the plan is to increase the upper measurement range to 300 l/h to close the gap in the measuring range of another test bench run with a hydrocarbon. |
