Yokogawa Rotameter Flow Meter, RAGN
The RAGN is a glass tube variable area flow meter designed for continuous flow measurement of liquids and gases, featuring a borosilicate glass metering tube with a brightly colored, easy-to-read scale. 

Actual flow is indicated by the top of the float and can be directly read from the scale on the metering tube.

Ideal for aggressive applications, the RAGN comes standard with in-line 316 stainless steel fittings and optional stainless steel, titanium, PTFE or PVDF floats. In addition, connection fittings can be chosen from either NPT thread or flanged connections.
Features
  • Simple, Non-Complex Design
    • Its complete stainless steel design gives the RAGN a higher corrosion resistance and no magnetic interferences with Reed switches.
  • Meets High Safety Standards
    • All RAGN rotameters are equipped with a turnable splinter shield and all materials conform to international standards. For SIL applications, RAGN rotameters have been assessed in accordance with SIL1 level on the basis of the IEC61508:2010. In addition, FMEDA reports are available to support SIL applications.
  • Maintenance Saving
    • With common applications and normal operating conditions, the RAGN is considered maintenance-free. In addition, many components are replaceable, allowing for in-field maintenance or service to be done without having to replace the meter, which reduces shutdown time.
  • Energy Efficient
    • Rotameters require little to no external power, greatly reducing a plant’s carbon footprint while lowering installation costs. The design of the rotameter reduces pressure loss, providing a more accurate flow rate measurement.
  • Other Features & Options
    • Optional limit switches with connection box to alert operator of system errors
    • Bistable inductive ring sensor, magnetic limit switch options
    • Percentage scale or dual scale options
    • Optional valves
    • Power supply for limit switches available
    • Custom designed upon request
