Abstract

Abstract

A new method for non-invasive flow measurement is described, To heat the pipe by a clamp-on heater, the temperature difference upstream and downstream caused by flowing fluid is changed into the resistance via Pt-film resistances. Then, the flowrate can be measured using a non-balancing bridge.
