For the problem of ultrasonic methane gas detectionaccuracy
a research on ultrasonic methane concentration detection system isproposed
established a mathematical model of sound velocity and gasconcentration Based on the ultrasonic direct measurement time differencemethod
the ultrahigh precision time digital conversion chip TDCGP21 is used tocomplete the precise measurement of time The design of ultrasonic methaneconcentration system was completed
and the main influencing factors ofmeasurement accuracy were analyzed Time measurement and solution were proposedThe system was tested and verified by methane gas The experimental results showthat the relative error of the detection method is less than 2% It has theadvantages of high precision
