Abstract
A high gain low noise amplifying system coupled with a properly synchronized switching circuit makes it possible to minimize the bulk of the magnet of an electromagnetic flow meter. Designs are described permitting blood flow measurements in arteries ranging from about 1 mm to over 15 mm in diameter. The magnet is energized with 400 cps AC. The base-line is established by switching off the magnet. Illustrations of blood flow changes in a conscious, freely moving animal in response to sensory stimuli are given.This publication has 2 references indexed in Scilit:
