Selection of flow meters
Thread Content
The testing medium is off-gas from the furnace (with an average molecular weight of around 21–22), containing approximately 30% water vapor at a temperature of about 550°C. The gas also contains a certain amount of dust; the exact amount is not known, but it is approximately 2–3 g/Nm3. Dear users in the instrumentation field, under such medium conditions, which type of flow meter can provide stable and relatively accurate measurements?
It is said that the V-cone method yields better measurement results
The V-type also has pressure tapping ports, right? Under such medium conditions, it’s prone to clogging, and its stability won’t be very good
The maximum operating temperature for vortex flowmeters is 500°C, so they may not be very suitable for such conditions
The wedge flow meter will work well when equipped with a flushing ring
