摘要
本文较全面的论述了温度变化对差压式液位计、浮力式液位计及超声波物位计在物位检测中对测量结果产生的影响,并且给出了消除温度变化引起的测量值误差的温度补偿方法,同时讨论这些方法的在实际应用中存在的不足。
This paper comprehensively discusses the influence of temperature change on the differential pressure level meter, buoyancy type liquid level gauge and ultrasonic level meter in object position detection for the measuring result, and gives the measurement to eliminate the temperature change caused by the temperature error compensation methods, and discussess the method which exists in the practical application.
