一种新型测定 API 比重的电子仪表能够自动而迅速地测定出60°F 时的比重,只用一个有读数的刻度盘即可,就不再使用玻璃比重计。如图所示,将液样盛在塑料瓶或常用的比重计量筒内,再将两个管子插入液样中,其中一个管子比另一个管子短6时,空气以每秒2～3个气泡的速度通过管子,由两个管子中出现的差动空气泡使两管之间产生压差,再通入灵敏的应变计转换成电信号,此信号即为液体比重,
A new type of electronic meter that measures API gravity automatically and quickly determines the specific gravity at 60 ° F. The glass hydrometer is no longer used with just one reading dial. As shown in the figure, the sample is stored in a plastic bottle or a common proportioning cylinder, and two tubes are inserted into the sample. One of the tubes is shorter than the other tube by 6 to 2 to 3 bubbles per second Of the speed through the tube, the two tubes appear in the differential air bubbles so that the pressure difference between the two tubes, and then into the sensitive strain gauge into electrical signals, the signal is the proportion of liquid,
