"All Metal" Flowmeters for Harsh Flow Applications of 0.80 thru 120 GPM liquids, 10.2 thru 1000 SCFM gases
Typical Flow Applications:
- Saturated Steam
- Hydraulic Fluid Metering
- High Pressure or Temperature Liquid and Gas flowmetering
- Opaque and dirty fluids
Features & Benefits:
- All metal construction for high pressures & temperatures
- Ideal for steam service, very dirty or opaque fluids, and harsh service environments.
- Internal magnet carries external indicator in a non-wetted enclosure.
- Extended flow ranges averaging 25 to 1.
- Disassembles in less than a minute without removing the meter from the pipeline.
- High temperature indicator option for service to 600°F.
- Standard 3/4" and 1-1/2" female NPT connections or optional flanges. Pipe adapters may be used for other sizes without affecting accuracy.
- Easily fitted with Flo-Sentry Single Point and Flo-Guardian Dual Point Alarms, KIST 4-20mA and Courier Remote Transmitters.

SPECIFICATIONS REPEATABILITY: ±1/2% of indicated flow rate. RANGEABILITY: 25 to 1 average. MATERIALS: Brass or T-316 stainless steel for body and internals, except for Alnico magnet (electroless nickel plating or encapsulation of the magnet available as an option). Stainless internals, which tend to be more abrasion resistant, can be supplied in brass bodies for liquids that contain abrasive particles. SCALES: Standard direct reading (GPM or LPM Liquid, Sp. Gr. = 1.00 or SCFM Dry Air @100 psig, 70°F.) or percentage scale. Scales are photo-etched, anodized aluminum. Special scales for other flow units or media conditions, or mylar scales for corrosive environments, are available at extra cost. Liquid meter scales for LPM Liquid, Sp. Gr. = 1.00, are stocked. Scale length is approximately 3.2 for Size 6 meters, 5.2 on Size 12 units. OPERATING LIMITS: Please Download Full Specifications. “O” RINGS: Buna N standard; Viton, Ethylene-Propylene (EPR), Silicone, Neoprene, Teflon and Kalrez optional. OPTIONS: Flo-Sentry and Flo-Guardian Alarms, KIST two-wire transmitters, and Courier Remote Display, Batching, or Mass Systems, high temperature service raceway (“Hot Top”), bumper option for surge and shock conditions, panel mount kits, threaded flanged connections, pressure gauges installed on the meter, special/multiple scaling, oxygen cleaning, and safety devices available. Custom options such as welded flanged connections, electroless nickel plating or other coatings, viscosity calibrations, etc., by quotation only. |
MEMFlo’s BUMPER OPTION FOR SURGE CONDITIONS It is important to remember that some surges are so severe that no amount of cushioning can guarantee protection from damage. Harsh surges should be designed out of the system. |
HIGH TEMPERATURE RACEWAY OPTION FOR FLUIDS OVER 275°F.
If exposed to prolonged temperatures of 275°F. or higher, the standard external plastic raceway may begin to bubble, distort, or even melt.
To accommodate temperatures up to 600°F., MEMFlo offers a “Hot Top” option for hot liquid, gas, and steam applications.
The standard raceway is replaced with the aluminum assembly shown above. Two set screws in the mounting rings hold the assembly in place. A small strip of safety glass covers the raceway and indicator.
Selecting MEMFlo “All Metal” Flowmeters
To choose a MEMFlo “All Metal” 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. When ordering or requesting a quotation, please specify:
- The Fluid Name
- Density or Specific Gravity
- Operating & Maximum Pressures & Temperatures
- Flow Rate (normal, minimum & maximum)
- Desired Accessories or Options (alarms, panel mounts, pressure gages, etc.)
- Special or Unusual Considerations (viscosity, environmental factors, etc.)
