in the last couple of years, ultrasonic meter a
device has established and considered the fastest-growing
new technologies in the oil and gas fields. The Orifice plate
problems are very uncertainty and very high cost in
maintained. The Ultrasonic Meters (USMs) have improved
in the petroleum career because they provide substantial
value to the clients by dropping the cost of doing the
commercial. More applications are existence planned
today using this technology. The main objectives of the
proposing USMs used in Alexandria City (IDKU Site
Plant) are to measure gas flow rate in Gas filed which have
more benefits over the orifice plate in reducing
measurement uncertainty to achieve the high accuracy
before export to the domestic grid. The aim of this paper is
to compare between USM and Orifice plate via simulation
and experimental results.
