Wedge flow meter
Thread Content
Are there any **standards** for wedge flowmeters? Or the relevant parameters of different wedge flow meters, etc.
I don’t think so; the instrumentation specifications I’ve seen don’t cover it
No, wedge flow meters are custom-made products. Standard orifice plates, standard Venturi tubes, long-neck nozzles, and ISA1932 nozzles all come with national standards, namely GB-T2624.X-2006
The wedge flow meter is a custom-designed device; it does not possess high accuracy among differential pressure flow meters. Its basic error is 3%, the calibration accuracy is 1%, the repeatability is 0.2%, and the range ratio is 10:1, with sizes ranging from DN20 to DN1000
