LibertyCES has documented Flow Meter in Acids service, including Hydrofluorosilicic Acid. Wetted materials to confirm: PVDF/PEEK and Zirconium Ceramic. Documented models include Blue-White MS6 and Icon Process Controls TI/TK/TK3. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
MS6 pre-calibrated chemical list includes hydrofluorosilicic acid; Icon markets 'Bulk Chemical' paddlewheel flow meters for acid service.

Icon's TI/TK paddlewheel line is explicitly built to retrofit into existing pipe fittings without replacing piping — relevant when upgrading acid-service flow metering on an existing line rather than a new build.
Hydrofluorosilicic acid is aggressive enough that body material alone doesn't settle the spec — Blue-White's MS6 names it in its 7-chemical factory calibration list, while Icon's TI/TK series substitutes a Zirconium Ceramic rotor and ETFE Tefzel paddle for the moving parts, a more specific material call than the generic PVC/PP/PVDF/316SS body options most vendors quote. James Riggins treats that rotor/paddle material as the real spec point on acid duty, since the wetted moving parts wear out before the body ever does.
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.
