In flow measurement, we require differential pressure.
since because, Flow= Square root(differential pressure).

to create differential pressure in a pipe, we insert orifice
plate inside the pipe. in which upstream pressure will be
higher than the downstream pressure of the orifice plate.
By taking tapping from the upstream and downstream, we can
obtain the differential pressure.
