在对于流量进行测试的时候，往往会使用标准孔板，它一般的情况下，它量一个测量差压的重要装置，在使用的时候，会配合差压计或者其他设备同时使用，比如孔板流量计，虽然它也是对于流量进行测试的一个设备，但是和其他的流量测量仪器有着一定的不同，它不但对于流量进行测量，同时也能更好的测量出温度、压力等等很多个数据，所以相对于其他来说，它在功能上面更加全面。因为在工业生产中，对于介质的要求是全方面的，不但要对于量有一定的掌握和要求，同时对于温度以及压力等等也都必须要掌握，也正是因为这样，标准孔板在现在的工业化时代中，也得到了很大的应用价值，它的应用范围也很广，可以适应于液、气任何介质，任何的流动性液体、蒸气、气体它也都能起到很好的测量，特别是在石化、化工以及电力部门上面的使用率zui高。
当然，它的优点并不是它的适应范围广，测量的方面比较全面，同时它还有智能操作的优势，也正是在化工上面的应用，必须要达到智能化的操作，如果不能达到这一点，很难应用工业化上面的应用。这是因为它在设计的时候，内部就有智能芯片，使用微机技术，也正是因为这样，它在使用和操作方面都很十分方便，即使没有人员在场，也都能达到全自动的操作，所以是现在流量测量的主要应用工具。
英文版本：
in the flow testing, often using standard orifice, it is generally the case, it is important for a measurement of the pressure difference, when in use, in conjunction with the simultaneous use of differential pressure gauge or other equipment, such as orifice flow meter, although it is a equipment for flow testing, but the flow measurement instrument and the other has a different, it not only for flow measurement, measurement of temperature, pressure and so on many data also can better, so relative to the other, it functions more complete. because in the industrial production, the media requirements in all aspects, not only have a certain degree of master and the requirements for quantity, at the same time, the temperature and pressure are all must master, it is precisely because of this, the standard orifice plate in the present era of industrialization, has also been a great application value, scope of application it is very wide, can adapt to the liquid, gas, in any medium, fluid, gas, steam any it also can play a good measurement, especially used in the petrochemical, chemical, electric power departments above the highest rate.
of course, its advantages and it is not suitable for a wide range of measurement, more comprehensive, and it has the advantages of inligent operation, it is also used in chemical industry above, must want to achieve inligent operation, if cannot achieve this point, it is difficult to apply in industrial application. this is because it is in the design time, internal have smart chip, the use of computer technology, it is precisely because of this, it is in the use and operation are very convenient, even without the presence of, also can achieve the automatic operation, so it is the main tool of flow measurement now.
