Fluid Components International (FCI) LLC FS10i details:
The FS10i is a universal flow switch and flow monitor designed for simple insertion into ½” (13mm) or larger diameter pipes and square ducts. The unit is suitable for either liquid or air/gas applications. It is fast responding and highly repeatable to both increasing and decreasing flow rate changes. The standard 1A relay trip point is easily set in the field for low or high trip. Point and the trip and reset points can be further tuned with hysteresis and time delay adjustments. Also included standard is a 4- 20mA trending output of the flow. Rate for connection to ancillary controls or alarm systems. The FS10i includes a 10-LED array which provides both an indication the trip point has been exceeded (LED flashes on/off) and of relative flow rate (10% increments) across the flow range.
