feature:

1.Imple structure,strong ,convenient installation.

2.Can measured all kinds od  flow of gas ,steam and wide usage.

3.Don't need real flow calibration, with moderate precision

4.Attachment is complete,it can design and calculation for the user

5. It can equiped with intelligent difference pressure transmitter,and realize temperature,pressure compensation or the scene concentric line communicating mode
