Regarding the selection for measuring flow rate, my true nature has shown again

Two flow meters were selected for use; since they are for internal use, high precision isn’t necessary – it’s sufficient to be able to read the flow values on-site. It’s still difficult for me, who’m not very good at reading instruments; the operating conditions are more or less like this. Pipeline 1: Temperature 27°C, flow rate 40 Nm3/h, pressure 0.15 Mpa. Pipeline 2: Temperature 27°C, flow rate 1.5 Nm3/h, pressure 0.1 Mpa. That’s all the information I have for now. I checked online and think that \"Float-type flow meters / Rotameter\" would be a suitable option. Does anyone have any simple suggestions? Thank you all.
Home gas meters cannot withstand very high pressures; their pressure tolerance usually does not exceed 50 KPa.
For local flow measurement, there’s also the metal float type; adding remote transmission will definitely make it more expensive
Are you sure it’s liquefied gas at these pressure and temperature conditions?
The process indicates that it’s a gas; I’ll check with him again to confirm
Liquefied gas is in liquid form; if it’s in gaseous form, it’s better not to use a rotameter, as it lacks compensation functions. You can opt for an vortex flowmeter or a balanced type, depending on your requirements regarding accuracy
The medium is liquefied petroleum gas, but it is in a gaseous state; so should it really be called liquefied petroleum gas? lol
If there are bubbles present, the rotameter will experience large fluctuations and become unreadable.
Okay, thank you for the reminder. What does this compensation mean?
