We offer variable area flow meters available to measure oil, phosphate esters, water and water-based fluids, as well as air and other compressed gases.

We generally supply two ranges of variable area flow meters or Rotameters, DFM plastic VA meters for vertical installation and the more advanced spring-loaded Hedland range of sharp edged orifice models for installation in any orientation.
