Steam measurement: Can a rotameter be used?
Thread Content
For existing steam at 140°C and 0.5 MPa, \"on-site measurement\" of instantaneous flow is required: Is a rotameter suitable for this purpose? What considerations should be taken when selecting one? ? Looking forward to guidance from industry professionals. . Also, are there any other types that are better and more convenient for use at the surface? Looking forward, looking forward
It should be fine. When making the selection, make sure the diameter isn’t too large, otherwise the rotor won’t be able to float, which will affect the measurement results
Vortex flowmeters are better; when the pressure is too low, the rotor cannot stay afloat, which results in poor accuracy at low flow rates. There is also the issue of temperature and pressure compensation. In my opinion, vortex flowmeters are the better choice.
For accurate measurements, it is recommended to use vortex flow meters. Rotors can be used as well, but their accuracy is certainly not as good as that of vortex flow meters!
I also agree that vortex flowmeters are better than float-type ones!
The rotor generally doesn’t seem to have on-site accumulation; I agree with the view from the 3rd floor – using vortex flow meters is a good option
Reply 1# *aoliu516: Metal tube float flow meters can only measure saturated steam; if a liquid crystal accumulator is also required, then the maximum temperature allowed is 120 degrees. This one doesn’t seem to belong to saturated steam. It is recommended to choose a vortex flow meter.
Agree with the view from floor 7. It belongs to superheated steam and requires temperature and pressure compensation; vortex flow meters or orifice plate flow meters can be used.
If the pipeline doesn’t vibrate, precision is required, so an vortex flow meter would be the better choice
It’s better to choose a vortex flow meter; float-type meters have quite a few issues. It can get stuck too when the steam is dirty.
Vortex flow meters or orifice plates are the best choice; rotors are not recommended. First, the structure of the rotor requires a special design when dealing with high-temperature media, and second, the cumulative functions of the rotor may not be as convenient as those of vortex flow meters. Another issue is precision; the precision of the rotor is too low.
