How about using a metal rotameter to measure acetic acid?
Thread Content
I see that many people use turbine flowmeters to measure acetic acid online; I’m thinking of using a magnetic float flowmeter instead. What do you think?
I saw online that electromagnetic flowmeters can be used to measure acetic acid. Acetic acid is a weak electrolyte, so how can an electromagnetic flowmeter be used to measure it?
Electromagnetic methods should work, as long as the conductivity is above 5 microsiemens per cm. If you use a metal tube float flow meter, the accuracy will be limited; otherwise, no other issues seem to prevent its use
It’s theoretically possible; pay attention to the material.
Metal tube rotameters have an accuracy of 2.5%; they can measure values where electromagnetic conductivity is above 5 us/cm. The accuracy of electromagnetic types is 0.5%, while that of vortex flowmeters is 0.75%. Choose the one that suits your needs, and pay attention to the material used to ensure corrosion resistance. For electromagnetic selection, be sure to choose a branded product.
The pressure is stable and the density is accurate; it can be used when high precision is not required. Electromagnetic flowmeters can measure tap water, let alone acetic acid.
Rotors are generally used to measure very small flow rates; I’m not aware of what the flow rate in question is. For metal rotors, the material used is a crucial factor – zirconium is required for handling acetic acid, and it’s not clear whether there are any manufacturers capable of producing such components
Electromagnetic flowmeters certainly offer high accuracy when measuring acetic acid, as well as excellent versatility. If a metal rotameter is used, a conical measuring tube with a PTFE lining and a metal float coated with PTFE must be selected. Large metal rotameter manufacturers can all choose those with an anti-corrosion lining. For glacial acetic acid, it may be necessary to choose a model with heating functionality, as its freezing point is around 17 degrees.
Precision is a key requirement; metal floats do not offer high precision, so turbines are the better choice
We generally do not choose turbines these days due to mechanical wear; instead, we prefer instruments without moving parts that can be used for a long time.
