CoFlo Fitting

Our new CoFLo design is a new way of looking at simplistic accurate DP measurement. It offers the same accurate and repeatable measurement qualities that you have come to expect in a standard single-chamber orifice fitting but with the following advantages.

Fabricators and end-users alike from around the globe will see cost savings advantages by utilizing the new innovative design. Not only does it provide a cost advantage over the Standard SC unit, but fabricators will also see cost savings during the design and manufacturing of the complete (end-use) ready meter tube construction.

The CoFlo fitting on the downstream portion of the orifice fitting reduces the required number of flanges that goes into a typical (WxF fitting) meter tube build. It eliminates the required or sought-after “companion flange” and the required gasket.

From a manufacturing perspective, it will reduce labor costs by eliminating one extra weld, one extra weld removal, and the risk involved in potential damage during such process.

The CoFlo fitting provides additional value by being the first of its kind to offer a wide array of ANSI class pressure ratings all in one fitting. This new design will allow 150 through 900 ANSI class requirements without further addition.

Available in 2″ through 4″ models, this is Canalta Flow Measurement bringing a new flavor of accurate, repeatable, and dependable measurement solutions to those that believe MEASUREMENT MATTERS.
