CM6G型气体热量计用于测量并控制样气的发热量和沃布指数(WI)。在该热量计中，样气和空气在燃烧器中燃烧，然后使用热电偶检测燃烧排气与燃烧器入口处给气的温差。
该热量计通过孔板检测出样气及空气的流速作为差压值，然后将差压转换成数字信号，再通过数字运算补偿流速变化。这种方法高度可靠，因而可用于钢厂和石化厂各种燃烧炉的热输入控制及民用燃气的热量控制。
flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
