Orifice flow meterMeasuring mass flow rate
High accuracy
Wide measuring range ratio
all in one standard/Integration 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 any industry fields as petroleum, chemical, power, textile, metallurgical, military and scientific research .
Features:
1.The structure of the throttle flow equipment is easy to copy . It has simple,stable ,reliable capability ,long working life and is very reasonable .
2.The orifice flow meter adopt the international standards and machining .
3.The orifice flow meter is worldwide usage which can measure all the signal-phase flow and it can measure part of mix-phase flow .
4.It is the standard throttle flow equipment which can use without actual flow to calibration .
5.The integrated type is easy to installation ,it can directly connect the differential pressure transducer and pressure transducer without leading a pressure pipe.
Main technical parameters:
Nominal diameter (mm): standard, DN50~1000; nonstandard, DN15~1000
