NON-INVASIVE ULTRASONIC FLOW MEASUREMENT METHOD FOR THE DETECTION OF FLOW RATES IN THE MICROLITER RANGE

Abstract

Particularly in medical technology, biotechnology or the pharmaceutical sector, very small quantities of fluids often have to be transported or dosed. Noninvasive measuring methods for flow rate or volume flow measurement that work without direct contact to the fluid and thus meeting the high hygiene standards of these industries hardly exist. Sensors available on the market are either not suitable for precise measurement of the smallest flow rates in the microliter range or are very expensive. For this field of applications, a retrofittable ultrasound-based flow sensor was developed in cooperation with the company ibidi GmbH, which can be integrated into an existing system consisting of very thin tubes or cannulas or capillaries as well as thin flexible tubes.
