    • Abstract
  • The principle of leakage measurement using differential pressure transducer is introduced. The effect of environmental temperature change is analyzed in view of the processes of differential pressure measurement. The amended formula with the temperature is givevn. the measurement method for effective volume of detected system is put forward.
