MEMFlo “P-72® Copolymer” Flowmeters for Caustic & Chlorine Flow Measurement
Typical Flow Applications:
- Chlorine flow meter
- Hot wet chlorine gas
- Chlorine dioxide
- Sodium hydroxide
- High pH sodium hypochlorite
- Brines
Features & Benefits:
- Heavy bodied meters specifically designed for demanding applications
- Flanged or female NPT connection options (flanged connections standard).
- Wetted materials are all P-72® Copolymer.Sight tubes may be glass, polysulfone, or P-72 (again, depending on fluid service)
- Offered in transparent tube models for clear fluids or magnetic indication for opaque fluids.
- Most models can be supplied with Flo-Sentry and Flo-Guardian Alarms, KIST 4-20mA Transmitters, Courier Remote Systems and other MEMFlo options & accessories

SPECIFICATIONS ACCURACY: ±2% of 100% flow rating standard REPEATABILITY: ±1/2% of indicated flow rate. RANGEABILITY: 25 to 1 average. MATERIALS: P-72 copolymer is the standard material for both the body and internals. Titanium, electroless nickel plated T310 stainless, and teflon internal components for maximum corrosion or abrasion resistance are offered as an option for certain service conditions. SCALES: Standard direct reading (GPM or LPM Liquid, Sp. Gr. = 1.00, or SCFM Dry Air @ 100 psig, 70°F.) or percent of flow. Scales are photo-etched, anodized aluminum. Special scales for other flow units or media conditions, or in other materials for corrosive environments, are available at extra cost. PRESSURE RATING: Up to 150 psig for flanged models, or 300 psig, depending on meter type, temperature, and service conditions. Operating limits of P-72 are basically the same as CPVC. TEMPERATURE RATING: Up to 212°F. (pressure ratings decrease at higher temperatures). OPTIONS: Flanged, threaded, or socket weld connections in standard or special sizes, Flo-Sentry Alarms, Flow or Mass Courier Systems, panel mount kits, special or multiple scaling, & safety devices available. Custom options such as viscosity calibrations are by quotation only. |
SIGHT TUBE OPTIONS POLYSULFONE: Only offered on P-72 flowmeters for compatible fluids that are transparent or translucent. Highly resistant to sodium hydroxide, many aqueous mineral acids, alkali, and salt solutions; good resistance to detergents and hydrocarbon oils. Temperatures to 300°F. (well above the limit of P-72). Attacked by nonpolar organic solvents such as ketones, halogenated hydrocarbons, and aromatic hydrocarbons. BOROSILICATE GLASS: Satisfactory for most acids, hot solutions (to 240°F.) below pH-12, and strong alkalis (to 20%) up to 100°F. Not recommended for water above 200°F., steam, fluorine, or hydrofluoric acid. Temperatures to 400°F. acceptable with non-attacking fluids. Glass sight tubes are permanently bonded in a P-72 or CPVC sleeve for mounting to the meter body. Al Safety Guard Tube that attaches to the sleeve is included. P-72: Uses an encapsulated magnet in the meter float to capture an external, flow indicator. Selecting MEMFlo P-72 FlowmetersTo choose a MEMFlo P-72 Flowmeter, please use the Sizing Calculators to obtain the correct equivalent flow. Find either the closest or next larger flow (whichever you prefer) in the “Designator & 100% Flow Column” of the Capacity Tables. Please review the Operating Limits in the specifications to chose a model style rated for your service conditions. To build the proper model number, please see Page 6.
