* * Fig.11.1 Representation of a tank with a liquid or solid material (hatched area), the product to be measured. The level sensor can be mounted (a) contacting product at the bottom, (b) as a contactless instrument on top, (c) as an intrusive sensor, or (d) at the sides as a level switch. 图11.1表示带有液体或固体物质的水槽(阴影区域),这个部分产品被测量。(a) 在底部水位传感器被安装得能够接触到产品(b)在顶部作为不接触仪器，(c)作为嵌入式传感器，(d)作为一个在侧面的液面开关。 Level Measurement * Unit 11 测控技术与仪器专业英语 Typical Measurement Technology Chapter 3 Introduction to Measurement/test Technology and Equipment * Words and Expressions monitor 监听器，监视器 cruising 巡游，巡航 vertical 垂直的，直立的，顶点的 onboard 随车携带的 barometric 大气压力 category 种类，别，范畴 surveillance 监视，监督 isobaric 表示等压的 topography 地形，地势 * Words and Expressions corrosion 侵蚀，腐蚀状态 galaxy 星河，星系 saturn 土星 spherical 球的，球形的 troposphere 对流层 martian 火星人，火星的 * Main content Altitude Measurement 1 Thickness Measurement 2 Distance Measurement 3 Level Measurement 4 * Altitude Measurement Accurate monitoring of aircraft cruising height is required in order to reduce vertical separation to a minimum standard. 飞机巡航高度的精确监控是为了降低垂直间隔至最低标准。 Interest here focuses on the measurement of the distance between aircraft level and the sea surface level. 这里令人关注的事集中在飞机航线和海平面水平之间的距离测量。 * This distance can be estimated onboard via barometric altimeters or it can be measured—either onboard or in ground stations—via electronic radio wave systems. onboard 随车携带的 这个距离可以通过气压测高计随机估计或可以通过地面卫星接收站或是飞机上的电子无线电波系统测量。 Altitude Measurement The indication of the first equipment is referred to as pressure altitude, or simply altitude, whereas that of the second category is referred to as geometric height or simply height. 第一类设备指示的是压力高度或者叫绝对海拔高度，而第二类是被称为几何高度或绝对水平高度。 * The altitude information at air traffic control (ATC) centers is based on pressure altitude measurement that the aircraft transponder system sends after it receives an appropriate interrogation—known
