Can someone give me a flow calculation specification of Rosemount 305 1 GP4A2B differential pressure transmitter in Rosemount?

I have QQ number 3037 1608, but the model of your differential pressure transmitter is not quite right. 305 1GP is the model of pressure transmitter. Why is there a flow calculation manual? Are you a Rosemount orifice flowmeter or a Rosemount A Niu flowmeter? The differential pressure transmitter between orifice plate and A Niu bus should be 305 1SC or 305 1C series ... Anyway, let's talk on QQ when you have time.
