Abstract

A gas flow sensor with small measurement range is developed.The structure and working principle of the sensor are introduced

and experimental verification of the sensor is made.The experiment results show that the sensor works well since its absolute error is less than 0.30mL and its relative error is less than 7.4% under the normal temperature and pressure conditions.The device is not only a gas sensor but also a gas flow or flow velocity sensor.The sensor has the characteristics of a fast response

high sensitivity

convenient installation

strong firmness

outstanding durableness

excellent cost effectiveness

etc.This sensor is usually suitable for any gas.
