Low Cost Sensor for Low Flow-Rate Measurement

Abstract

Many times in industrial application, measurement of very low flow rates is required with fair accuracy. Fluids like natural gas, petroleum and oxygen are supplied to customers on a continuous basis through dedicated pipelines, precise online measurement of quantum of supply is essential for payment purpose. The present work has aimed to design a sensor to measure low flow rate accurately, this sensor uses the important properties of the thermistor, it's self-heating, and its fluid flows sensing property, at the same time efforts have been made to keep it cost effective
