ERDCO See-Flo meters indicate flow rate and permit visual inspection of water, air or other transparent fluids. For general purpose industrial service, See-Flo meters handle a wide range of process fluids in vertical or horizontal piping runs.

The wedge shape of the meter housing makes See-Flo practically self-cleaning. Where periodic maintenance might be necessary, the tempered glass window is easily removed and replaced. Because of its large internal cavities this product will not plug up like the old glass tube "rotameters".

Each flowmeter is calibrated to be direct reading for the liquid or gas operating conditions that you specify. Scales with special engineering units and dual units of measure are available.

Applications: Transparent Liquid or Gases
Functions: Direct Reading flow rate and Observe fluid condition
Features: Lowest Cost Meter; No power required; Calibrated for application conditions

Long Service life due to simple design.

ERDCO Engineering Company SEE-FLO meters are variable area flow meters (rotameter). The internal volume of the housing enlarges from the inlet to the outlet. The primary element is a tempered alloy vane with one end affixed to the apex of the meter housing. As the flow changes, the vane is flexed in direct proportion.
