Principle and structure______________________________________________
QZL mass flow meter is working by thermal theory, sensor output voltage proportional to the mass of air or other gas which flow through the internal sensing element. Signal output will be passed onto the second part of the meter which will display the reading and output DC signal for long distance computer control
