AMS Instrumentation and Calibration supplies a wide range of industrial and instrumentation equipment across Australia. They provide FS10A Flow Switch/Monitor from Fluid Components International (FCI) represents the lowest-cost solution for continuously verifying flows within liquid or gas process analyser sampling systems. FS10A Analyser Flow Switch is a small, lightweight instrument featuring large low flow sensitivity, a choice of electronic outputs and a no-moving parts design that ensures maximum reliability. Analyser end-users or system integrators will find the advanced electronics and thermal dispersion flow sensing technology of the flow analyser providing an overall solution to sampling system flow assurance. It is suitable for continuous monitoring of analyser sample flows to provide the integrity process analysis without interruption.
The precision flow sensor element of FS10A Analyser Flow Switch has no moving parts to foul, clog or maintain, ensuring continuous reliability and requiring virtually no maintenance. Unlike capillary bypass flow meters and controllers, this analyser has no cavities, orifices or dead-legs that can trap fluids and lead to contaminated samples, which preserves sample integrity and provides faster system sampling times. Instrument’s wetted parts are corrosion-resistant 316L stainless steel that comes with Hastelloy-C sensor tips. The FS10A Analyser Flow Switch is designed for use with different types of process and emissions sampling systems, including gas chromatographs (GCs), mass spectrometers, optical spectrometers and photometers. It fits in a standard ¼ inch tube tee or SP76 adapter. The flow analyser conforms to NeSSI Generation I and is prepped for Generation II and III compliance. It requires only a single 1.5-x-1.5-inch SP76 base.
The FS10A Analyser Flow Switch operates over a wide flow range, depending on the configuration. The flow range in air varies from 50 cc/min to 10,000 cc/min, and the flow range in water is 4 cc/min to 100 cc/min. It accommodates wide turndowns with a ratio up to 100:1. The FS10A Analyser Flow Switch’s electronics are packaged in a rugged, fully-sealed aluminium housing. The electronics can be integral mounted with the sensor element in a uni-body configuration or remotely mounted for easy front panel display viewing. The FS10 features a top-mounted, 10 LED array and two pressure-sensitive button touch controls. The LED display provides users visibility of flow rate trend, alarm status and power on/off. The flow switch’s set-up and setpoint values can be changed using the two push-buttons or the standard RS232C serial interface.
The FS10A switch output can be either an open collector (transistor) or a 1A relay settable for NO or NC operation. The switch settings are user programmable for trip control of hysteresis and time delay. An optional 4-20 mA output is available for trending, which is settable to represent flow rate in mass flow or standard volume units.
