DIGMESA micro flowmeter has nearly a hundred sub models, covering a flow range of 0.027-30L/min, with an accuracy of ± 2%, repeatability of ± 0.25%, a pressure of 10 bar at 20 ℃, a temperature of -10-100 ℃, and pulse signal output (if displayed, not available). Each model has a flow curve and pressure loss curve. Both viscous liquids and highly corrosive liquids have specific models that can be tested.

Regarding the characteristics of acetone,O-ring FPMDIGMESA micro flowmeter for measuring acetoneAdopting PPS material shell, the internal sealing O-ring adopts FPM resistant material, and the impeller adopts PFA material.

PPS, also known as polyphenylene sulfide, is a material with strong chemical stability that does not dissolve or swell in organic solvents such as toluene and acetone. 40% GF represents a glass fiber reinforcement ratio of 40%. The addition of glass fiber mainly improves the mechanical strength, rigidity, and heat resistance of PPS material, and generally does not affect the chemical resistance of PPS itself. So, PPS40% GF material has good resistance to acetone.

1. Fluororubber (FKM/VITON)

• Chemical properties: The molecular structure contains a large number of fluorine atoms, with strong polarity and excellent tolerance to polar solvents such as acetone, esters, and ethers. It is not easily swollen or degraded.

• FPM (commonly known as FKM/VITON) molecules contain a large number of fluorine atoms, and the strong electronegativity of fluorine atoms makes the molecular chain polarity good, which can effectively resist the erosion of polar solvents such as acetone, esters, and ethers.

• Acetone, as a polar organic solvent, is difficult to break the molecular chain or cross-linking structure of FPM, so FPM hardly undergoes significant swelling, dissolution, or performance degradation in acetone.
