What LibertyCES's vendor documentation shows
Two real engineering constraints to publish alongside the catalog. First, minimum conductivity: the 2551 and 2552 both require 20 µS/cm, so they will not work on deionized or ultrapure water — that is where the 2100 turbine, 2507 paddlewheel or a clamp-on ultrasonic takes over. Second, Signet's recurring tip: for liquids containing ferrous particles use magmeters, not paddlewheel or turbine sensors, and for multi-material systems always reference the max temperature/pressure spec to the lowest-rated component. The 2536 PVC-body variant's explicit 12.5% sodium hypochlorite rating is an independent instrumentation-category confirmation of the project's existing hypochlorite guidance. Icon's Kalrez FFKM option is the documented escalation path when Viton is the limiting component.

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.
FAQ
Is Magmeter / Paddlewheel / Turbine Flow Meter compatible with Water/Aqueous?
Two real engineering constraints to publish alongside the catalog.

Icon's Kalrez FFKM option is the documented escalation path when Viton is the limiting component. This is strong evidence.
