My dear Sam, the question submitter may be new for the
instrumentation, plz dont discourage him or the people who
ask like this type of questions.

My dear friend Mayur.kevadiya, the DP range of the flow
transmitter will not be with this much ranged values, it
will be in 0~100inWC, 0-2500mmWC, 0~100mbar, 0~200kPa such
like low ranges.

And only with the DP range we can not say the line flow, to
find that we need more data, such as, line size, orifice
bore dia, line pressure, flow density, flow coefficient,
etc.
