High Accuracy with em-tec BioProTT™ flow measurement system proven in customer environment
Since the late 1980s, there have been more than 20 indirect methods for measuring process flows for the bio-pharmaceutical industry. Few of these methods are well suited to single use systems. Non invasive transit-time ultrasonic flow measurement with Clamp-On technology can the achieve overall performance accuracy and repeatability required for typical process control applications. AlphaBio, Inc has evaluated three different single use system set-ups (TFF System, Isocratic Chromatography System and Gradient Chromatography System) with the em-tec BioProTT™ flow measurement system. Flow rates ranging from 2 to 16 LPM were measured and evaluated against an NIST calibrated Coriolis meter (Endress + Hauser.) The results of this study indicate that that with proper material calibration and unit setup, flow rate measurement accuracies of less than +/- 2% of reading can be achieved.
