AMS FS10A universal flow switch

Click2Contact

The FS10A is a universal flow switch and monitor specifically designed for gas and liquid process analyser sampling systems. It is a fast responding, highly repeatable sensor which installs easily into a standard tube tee fitting or new SP76 (NeSSI) modular manifold.

The product utilises thermal dispersion flow measurement technology with FCI proprietary equal mass sensing for sensitivity and repeatability. The instrument’s wetted parts are corrosion-resistant 316L stainless steel with Hastelloy C-22 sensor tips. The sensor element has no moving parts to foul, clog or maintain to boost reliability and reduce maintenance costs. There are no cavities, orifices or dead-legs to trap or contaminate samples, which preserves sample integrity and allows for faster system sampling times.

The electronics are packaged in a rugged, fully sealed, aluminium housing which provides protection and a long product life under all process conditions. The electronics can be integral mounted with the sensor element resulting in a unibody, self-contained unit or the electronics can be separated from the sensor for remote mounting. The remote configuration is useful when the sensor installation area is subjected to high temperatures or to mount the front panel and display in a more convenient location.

The instrument provides a top-mounted, flow rate monitoring LED array for at-a-glance visual indication of proper flow rate to the analyser or sampling system, that an alarm/trip has been reached and as indication the unit is powered and operating. The flow switch’s setpoint is conveniently user-settable via two push-buttons accessible at the top of the unit or via the RS232C I/O port.
