摘　　要：现行的检测手段已经不能满足现代油料计量的发展要求,研究一种精度高的在线检测装置十分必要。利用超声波纵波的特性,提出一种利用超声波在油料中传播的时间差和相位差两项指标综合判定油料密度的方法,并设计了检测装置。通过试验证明:该装置具有稳定性好、灵敏度高、测量范围广、自动化程度高、响应速度快以及抗暴性能好等特点,完全可以满足油料密度在线检测的需要。Current detection means can＇ t already meet the demand for development of the modem oil measurement,it is very essential to study a kind of online measuring device with high precision. Utilizing the characteristic of the ultrasonic longitudinal wave, a new method that judges the density of oil by measuring time difference and phase place is put forward, and an instrument is designed. Experiments prove that the instrument has the characteristics of good stability, high sensitivity, wide t range, high automation,quick response and explosion resistance. It can meet the need of the oil density mesurement
