Abstract
The invention relates to an interface measuring device, which comprises a membrane and a wave guide rod, wherein the membrane is slidably connected with the wave guide rod; and the density of the membrane is less than the density of a lower measured medium and is greater than the density of an upper measured medium. The use of the device comprises the following steps of: (1) penetrating the membrane into the radar wave guide rod, freely sliding on the wave guide rod, and meanwhile arranging a limiting device at the bottommost end of the wave guide rod, thereby preventing the membrane from being separated from the wave guide rod during sliding; and (2) inserting the interface measuring device into a container in which the measured medium is loaded, floating the membrane on an interface of the upper medium and the lower medium, and adjusting radar reflection wave to produce reflection on the membrane so as to obtain interface liquid level. The interface measuring device has the advantages of simple structure, quick, simple, convenient and reliable measuring method and capabilities of accurately measuring the interface liquid level and simultaneously measuring the heights of the two mediums, particularly measuring the liquid level with foam.
