The flow and measurement application specialist said the FS10i Flow Switch/Monitor is particularly useful in gas flow safety-related applications because it is designed to provide a dependable high or low trip point alarm. It also includes an analog 4-20 mA output signal.

Its full range capacity can be employed in gas applications, including hazardous gases. With its optional Div 2/Zone 2 approvals, the FS10i is suited for applications monitoring seal leaks, compressed air leaks, and assuring that purge air flow is verified. The FS10i’s analog span is established by simulating low flow and high flow conditions under the setup mode. The 4-20mA output, though non-linear, will now track the flow over that range.

The company says the FS10i’s analog output is ideal for trending flows that can provide an early warning of clogged filters, pipe fitting leaks, wearing seals, pump problems and other causes of flow disruptions before system shutdown. This instrument’s capabilities are a highly useful tool in avoiding damage to expensive pumps and compressors and other equipment that can require extensive maintenance or replacement.

It has been designed for simple insertion into 0.5-inch (13mm) or larger diameter pipes and square ducts. It is fast responding and highly repeatable to both increasing and decreasing changes in flow rate. This switch/monitor also includes a 10-LED array that provides both a useful visual indication that the trip point has been exceeded (LED flashes on/off) and of relative flow rate (10 percent increments) across the flow range.

The FS10i flow sensor’s thermowells are constructed of highly corrosion resistant Hastelloy C-22. It operates in fluid temperatures up to 121°C, in pressures up to 2000 psi [138 bar] and also features IP protection rating to IP67 for its housing.
