目前关于料位测量的仪器,虽然在液体料位测量中取得了很大的成绩;但固体料位测量一直是个难题,很难有一个准确可靠的最佳测量方式。过去以接触式物理测量仪器主,这种机械式仪表故障多,寿命短。近年来,非接触式物位计在测量固体物料上显示出各自特点,使固体物料料位的测量水平显著提高。其中雷达波料位计在环境恶劣的场合其无接触测量的优势得以充分体现。 At present, the instrument for level measurement has made great achievements in liquid level measurement. However, solid level measurement has always been a difficult problem and it is very hard to have an accurate and reliable measurement method. In the past to contact the main physical measurement instruments, mechanical failure of this multi-instrument, short life expectancy. In recent years, non-contact level gauges have shown their own characteristics in the measurement of solid materials, the level of solid material level measurement significantly increased. Among them, the advantage of the non-contact measurement of the radar wave level gauge in the harsh environment can be fully reflected.
