Sealing material
There are other elastomeric seal choices available, such as:
The selection of elastomeric sealing material for mass flow meters must be based on chemical resistance at operating conditions. Bronkhorst has gathered a lot of information about the compatibility of various compounds and we can advise our customers accordingly.
Another area to be aware of for chemical resistance is the body and sensor material of the mass flow meter. Stainless steel is a common material used for the body and sensor, but applications with particularly aggressive chemicals may require a Hastelloy sensor, or a sensor coated for higher chemical resistance.
In conjunction with the advice from Bronkhorst, a useful website for helping you decide which elastomeric seal or sensor material are appropriate for your application is: the
DuPont Chemical Resistance Guide.
