Description
The GF 2581 FlowtraMag is a full-bore plastic PVC in-line style magnetic fl owmeter. The
PVC body with Titanium or Hastelloy
three times lighter in weight compared to traditional metal magmeters on the market. It is
designed for high accuracy fl ow measurement in short pipe runs, making it an ideal solution
for industrial applications where performance and ease of use are important.
The FlowtraMag is available in pipe sizes of DN25 (1 in.), DN40 (1.5 in.), DN50 (2 in.),
DN80 (3 in.) and DN100 (4 in.), optimized for performance in short pipe runs often
associated with fi nal effl uent lines, well heads and water treatment skids.
