摘要
针对超声波流量计在测试中存在零位漂移,造成测试误差较大的问题,本文通过研究超声波换能器零位漂移特性,探索用函数拟合系数的方式标定零位漂移特性的可行性。
In view of the zero drift of ultrasonic flowmeter in testing,the problem of large test error is caused. By studying the zero drift characteristics of ultrasonic transducers,the feasibility of calibrating zero drift characteristics with function fitting coefficients is explored.
