Install / Failure Note

Blue-White ships the MS6 factory pre-calibrated for only 7 named chemicals, including 12.5% sodium hypochlorite; a chemical outside that list requires a factory custom calibration with no published price or turnaround. Separately, GF Signet's concentrated-hypochlorite rating on the 2536 paddlewheel is specific to the PVC-body variant, which is size-limited to DN15-DN100 — the PP/PVDF-body versions of the same sensor run up to DN900 but don't carry the same explicit NaOCl claim.

Sodium hypochlorite degrades wetted components that aren't specifically rated for it, so a flow sensor spec'd on body material alone can still fail even when the body is nominally NaOCl-compatible. Liberty CES cross-checks two independent factory confirmations — Blue-White's MS6 pre-calibration list and GF Signet's PVC-body 2536 rating — before specifying instrumentation for concentrated hypochlorite service, rather than assuming any PVDF- or PVC-tagged meter is automatically safe at 12.5%.

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.
