Abstract

The upper drawing shows the measuring apparatus in which the fluid, whose flow is to be measured, enters through the jet A and exits by way of the outlet B. The impingement of the fluid on the diaphragm C causes a force which displaces the shaft of the linear potentiometer D. The voltage drop across the active part of the potentiometer (lower drawing) is measured with a voltmeter E, which is calibrated to read in flow units. As flow increases the potentiometer shaft is displaced further, which results in an increased reading on the voltmeter. The spring F returns the diaphragm to its normal position.
