FS10i Flow Switch and Monitor
Product Overview
The FS10i is a universal flow switch and flow monitor designed for simple insertion into ½” (13mm) or larger diameter pipes and square ducts. Suitable for either liquid or air/gas applications it is fast responding and highly repeatable to both increasing and decreasing flow rate changes.
Providing best-in-class features, the FS10i is ideal for rugged duty applications and is built for long-life usage in a range of other industrial process applications. For more information about the FS10i flow switch and monitor, contact a Cross process solutions expert.
As an exclusive representative for Fluid Components International, Cross offers the complete line of FCI flow equipment throughout our territories in the mid-Atlantic area, including; Maryland, Virginia, and Washington D.C.
