摘要
在高温高压容器中采用差压式水位计测量水位的方法，通常由于容器中介质密度的变化给测量带来很大误差。为了提高高通量工程试验堆 (HFETR)试验回路稳压器水位测量精度，本文将介质密度随压力变化的函数关系输入测量仪表中，使稳压器的水位测量实现了介质密度的自动补偿。经试验标定和系统运行证明，此测量系统具有稳定性好、测量精度高和补偿范围大等特点。
When a differential pressure water- level gauge is used to measure the water- level in the vessel,large uncertainty can be induced because of the change of media density in the vessel.In order to raise the precision of water- level measurement for pressurizer of High- Flux Engineering Test Reactor (HFETR) Test loop,the auto- compensation of the density has been realized in the measurement of water- level through putting the functions that the density changes with the pressure into the measuring meter.Experiment and operation have confirmed that the system has the properties of the stability,high precision,large range of compensation,etc.
