Rotameters


Quick Overview

Rotameters of series RM, RMF, RMA, GOST 13045-81, are designed for measuring the volume flow rate of smoothly changing homogeneous flows of pure and slightly contaminated liquids and gases with dispersed inclusions of foreign particles.
  
Optionally, they are made in tropical and marine design.
  Rotameters of RSB type are designed for measuring oil consumption in the centralized lubrication system of paper-making machines.

   Optionally, they are made in tropical and marine design.
  Rotameters of RSB type are designed for measuring oil consumption in the centralized lubrication system of paper-making machines.
  Rotameter RMF GOST 13045-81 is designed for measuring stable or smoothly changing (non-pulsating) flows of non-crystallizing liquids and gases that are neutral with respect to glass, PTFE-4, and gland packing FUM-B.

  • Stability of measurement accuracy even at very low flow rates, the standard range is 10: 1 (the ratio of the upper measuring limit to the lower one), suitable even at low operating pressure;
  • Minimum pressure loss;
  • Local indication, which does not require auxiliary energy;
  • The straight sections of the pipeline "before" and "after" are very short or do not require replacement of the main units;
  • Accurate calculation of the scale for the working product according to VDI.
