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.
