See-Flo 3200 Erdco Meters indicate flow rate

Erdco See-Flo 3200 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.

Features

• Instantaneous flow rate measurement.
• Observe fluid conditions for color, clarity, and flow.
• Use in horizontal or vertical piping systems.
• Individually calibrated for fluid and operating conditions.
• User-selectable 10:1 turndown flow ranges. (See Meter Rangeability Sizing Tables)
• User-selectable units of measure including dual units of measure.
• No floats to get stuck, tubes to break or dynamic seals to leak.
• Low-pressure loss.
• Simple design with few parts for long service life.

Principle of operation

Erdco Armor-Flo^TM meters are variable area flow rate meters (“rotameter”). See-Flo® meters are variable area flow rate 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 rate changes, the vane is flexed in direct proportion.

The ¹/₂“, ³/₄“, and 1” connections typically have female threaded ends. Sizes 1 ¹/₄” through 12″ utilize an integral by-pass housing enables larger connection sizes in the format of a spool with a consistent 12″ end to end dimension. In addition, it permits a wide variety of connection types which include threaded, flanged, grooved ends and tri-clamp.
