The Model FS10A Analyzer Flow Switch/Monitor from Fluid Components International (FCI) ensures flow to water or gas sampling systems or analyzers. The FS10A Flow Switch/Monitor is designed for use with tubing from 1/8 inch to ½ inch and the electronics may be either integrally mounted or remote mounted from the sensor element. It is extremely sensitive to low flow rate detection, there are no moving parts to foul or clog, and there are no cavities, orifices or dead-legs to trap or contaminate samples. FS10A is suitable for application in liquid or gas analyzer sampling systems. It is small, lightweight and features a choice of electronic outputs including open collector, relay and 4-20mA outputs. Limit alarms are also user programmable for time delay and/or hysteresis. An on-board 10-LED array provides at-a-glance visual indication to the user of flow rate and whether the alarm limit has been tripped. All FS10A set-up parameters can be performed via its two front panel push buttons or via a PC over its RS232C I/O. Its exclusive “learn” mode facilitates easy user set-up of flow range zero and span settings. Water and wastewater end-users and system integrators will find FCI’s FS10A provides a superior overall solution for sampling system and analyzer flow assurance. With its advanced electronics and ultra-reliable thermal dispersion flow sensing technology it will ensure the highest integrity process analysis without interruption.
