SERIES FMF & FMP DOUBLE WINDOW VISUAL SIGHT FLOW INDICATOR – LARGE

Double Window Visual Sight Flow Indicators for liquids, air or gases

The Double Window Flow Indicators from SURE FLOW PRODUCTS, LLC are most useful where visual inspection of the
pipeline flow (motion, flow, or color) is required as a plant safety or as a means to verify adequate flow for production
quality during process conditions. These robust double window sight flow indicators are also excellent for verifying flow for cooling, quenching, or lubricating of parts or equipment such as but not limited to: pumps engines, gears, and
compressors. The sizeable windows allow an excellent view of the conditions in the line from a relatively long distance.

With two styles to choose from the Spout design provides visual inspection of the fluid while the hinged internal Flap design with its graduated scale allows a check on flow rate changes and/or repeatability of the valve positioning while providing view of the process. The Flap or Spout can be used in transparent or slightly opaque solutions and gas services. Both styles will operate in horizontal or vertical orientation (Flap style with vertical mount – Flow up only). Offered in connection sizes from 1/4 inch to 4 inches with NPT, BSP, or Flanged Connections with flow to beyond 500 GPM (2000LPM).

FEATURES/BENEFITS:

  • Double Window Visual Flow Indicator
  • For use with Liquids, Air or Gases
  • Dimensions from 1 1/4-inches to 4-inches
  • Great for Visual Inspection of the Pipeline Flow (Motion, Flow or Color)
