( RS485/ 4~ 20mA/ pulse etc.) for data process. The series cover the DN range from 25 to 100 mm with an accuracy of ± ( 1.5+ 0.5FS) % or better depending on the requests. The meters can work at an environment of -20 to 60C and pressure up to 1.5 MPa. The package ensures hygienic safety and can be used for beverage and food industrial gas process such as CO. Other applications include special 2 gas monitoring in steel process, hydrogen flow control in chemical industry, process gases ( oxygen, nitrogen, helium, compressed air or argon) monitoring in manufacture, to name a few.
