All in one standard orifice flow meter is one kind of differential pressure flow meter which fitted with standard orifice throttling element. It has long history; plenty reference material on both theory and practice, mature on usage. It is the most popular flow meter which widely used in many field.
The throttling element of standard orifice flow meter is strictly following the international standard for design, manufacture, installation and operation. It doesn’t require real-calibration for flow rate measuring or estimating the inaccuracy. It is widely used in many industry fields as petroleum, chemical, power, textile, metallurgical, military and scientific research.
