LibertyCES has documented Flow Meter in Caustics/Bases service, including Aqueous Ammonia and Ammonium Hydroxide. Wetted materials to confirm: PVDF/PEEK. Documented models include Blue-White MS6. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
MS6 pre-calibration list includes both ammonia species.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| MS6 factory-calibrated concentrations | Aqueous Ammonia 10%, Ammonium Hydroxide 30% | Blue-White Industries — Flow Meters |
| MS6 max pressure | 200 psi (13.78 bar) | Blue-White Industries — Flow Meters |
| MS6 max temperature | 104°F (40°C) | Blue-White Industries — Flow Meters |
| MS6 wetted materials | PVDF, PEEK | Blue-White Industries — Flow Meters |
Both ammonia species sit inside MS6's narrow 7-chemical factory pre-calibration list; a customer running a different ammonia concentration or a different amine altogether needs Blue-White's custom-calibration path, not an assumption that PVDF/PEEK construction alone covers it.
Ammonia and ammonium hydroxide are common caustic-service fluids in water treatment, but 'PVDF-bodied meter' is not the same claim as 'factory-calibrated for this exact concentration' — Liberty CES quotes the MS6 for 10% aqueous ammonia or 30% ammonium hydroxide specifically because Blue-White's own pre-calibration list names those concentrations, not because PVDF is broadly ammonia-resistant.
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.
