Abstract
This paper presents the fabrication of a micro electromagnetic flowmeter for liquid flow rate measurement. The flowmeter consists of a silicon flow channel with two electrodes and two permanent magnets. The micro flow channel and the detection electrodes are fabricated by the anisotropic etching of two silicon substrates and the metal evaporation process respectively. If conductive fluid passes through a magnet field, electromotive force is generated and detected by two electrodes. When the flow rate is 2.6 ml/sec, the measured output voltage is 7.4 mV.
