GF Signet's own recurring field guidance applies directly to this category: for liquids containing ferrous particles, use magmeters rather than paddlewheel or turbine sensors, and on any multi-material flow-instrumentation system, always reference the max temperature/pressure rating to the single lowest-rated component in the assembly — not the average or the highest-rated part.
The 20 µS/cm minimum-conductivity requirement on GF Signet's own insertion magmeters is a hard physics exclusion, not a material-compatibility question — a magmeter cannot read deionized or ultrapure water no matter what body material is quoted, exactly the kind of spec error a generic parts list misses. Liberty CES cross-checks the flow technology against the water chemistry first, then the wetted material second, because getting the technology wrong isn't fixable with a material upgrade.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
