May I ask which flow meter offers good cost-performance for measuring hydrofluoric acid?
Thread Content
10% hydrofluoric acid, 20% hydrochloric acid, and approximately 0.125% fluorocarbon organic compounds; temperature range from room temperature to -40°C, pressure range from normal pressure to 0.4 MPa. Is there a suitable material for the electrodes of electromagnetic flowmeters? Are there any better flowmeters that don’t use electromagnetic flow measurement? (No rotameter used)
For measuring media containing hydrofluoric acid, an electromagnetic flowmeter is a common and suitable choice, as it can handle highly corrosive liquids without being affected by contamination from the medium. For electrode materials, it is recommended to use Hastelloy or titanium (Ti), as these materials possess excellent corrosion resistance and are particularly suitable for handling media containing hydrofluoric acid. In addition to electromagnetic flowmeters, you can also consider using mass flowmeters, such as thermal mass flowmeters or Coriolis mass flowmeters. These flowmeters can provide accurate flow measurement and are suitable for a wide range of industrial applications. Coriolis mass flow meters are particularly highly regarded for their high precision and compatibility with a wide range of chemical media. However, their cost may be higher than that of electromagnetic flowmeters; therefore, you need to decide whether to use this type of flowmeter based on your budget and specific requirements. .
