一、流量计的使用和选型原则流量计的正确使用和选择并不是一件容易的事情。因此,要正确和有效地选择流量计,首先不仅要深入了解各种流量计的结构原理和流体特性等方面的知识,还要根据使用现场的具体情况并考察周边的环境条件进行选择,同时也要统筹考虑经济方面的因素。一般情况下,主要应综合考虑以下5个方面的选择因素:(1)流量计的性能要求;(2)流体特性;(3)安装要求;(4)环境条件;(5)流量计的价格。 First, the use of flowmeter and selection principle The correct use of flowmeter and the choice is not an easy task. Therefore, to correctly and effectively select the flowmeter, we must not only understand the structure principle and fluid characteristics of various flowmeters in depth, but also select according to the specific conditions of the site and the surrounding environmental conditions, To consider the economic factors. In general, the following five factors should be considered: (1) the performance requirements of the flowmeter; (2) the fluid characteristics; (3) the installation requirements; (4) the environmental conditions; (5) the price of the flowmeter .
