液位测量在船舶运输中有着广泛应用,如油舱、燃油柜、锅炉水、水柜、压舱水、舱底水的液位测量等都具有重要的意义。船上液位测量的特点是液体种类多,即工质多变,海水的温差很大,容器又经常处于倾斜摇晃的环境之中,船用检测仪表要求安全可靠、操作简便。这些条件使通常在陆地上使用的液位计在船舶上的运用受到种种限制。 Level measurement is widely used in ship transportation. It is of great significance to measure the liquid level of oil tank, fuel tank, boiler water, water tank, ballast water and bilge water. The characteristic of liquid level measurement on ships is that there are many kinds of liquids, that is, the working fluid is varied, the temperature difference of seawater is very big, and the container is often in an inclined shaking environment. The marine instrumentation requires safety and reliability and is easy to operate. These conditions subject the level gauges normally used on land to restrictions on the operation of ships.
