The FS10A flow monitor is a versatile and reliable tool for monitoring flow in analyzer sampling systems. It is a small, lightweight instrument that is easy to install and maintain.
Engineers can be responsible for demanding or hazardous process areas where the continuous verification of gas or liquid analyzer performance is essential to safety, quality and productivity. They will find the FS10A Analyzer Flow Switch/Monitor from Fluid Components International (FCI) provides the required dependability, accuracy and responsiveness necessary to meet their requirements.
FCI’s FS10A Analyzer Flow Switch/Monitor is a sophisticated universal flow switch and monitor specifically designed for gas and liquid process analyzer sampling systems. The FS10A is a fast-responding, highly repeatable sensor, which installs easily into a standard tube tee fitting or the SP76 (NeSSI) modular manifold.
In a wide range of industries, the close control of many toxic and/or combustible gases requires the continuous monitoring of analyzers. This is to ensure their safe, effective use to protect employees and assure end-product quality. Validation of uninterrupted flow to the analyzer is necessary to alert system operators in the event of failure. That might include blocked sample tubes, stuck valves or any other number of potential issues.
Why FCI is providing excellent technology for its flow monitor
Utilizing FCI’s long-proven thermal dispersion flow measurement technology, the FS10A Analyzer Flow/Switch Monitor is designed with proprietary equal mass sensing to achieve outstanding sensitivity and repeatability. The instrument’s wetted parts are superior corrosion-resistant 316L stainless steel with Hastelloy C-22 sensor tips. The sensor element has no moving parts to foul, clog or maintain, which ensures continuous reliability and virtually no maintenance. There are no cavities, orifices or dead legs to trap or contaminate samples, which preserves sample integrity and faster sampling times.
This instrument’s electronics are packaged in a rugged, fully-sealed, stainless steel housing. It provides the Model FS10A with exceptional protection and long life under all process conditions with virtually no maintenance. The electronics can be integral when mounted with the sensor element. This results in a uni-body, self-contained unit. Alternatively, the electronics can be remotely mounted away from the sensor element.
The instrument’s remote configuration is Div 1/Zone 1 FM approved for hazardous environments. The remote configuration is useful when the sensor’s installation area is subjected to high temperatures. It’s also helpful for mounting directly to the front panel of the analyzer. This places its display in a more convenient location for technician viewing.
Specifications of the flow monitor
The FS10A Analyzer Flow Switch/Monitor is designed with an easy-to-read top-mounted, flow rate monitoring LED array. Users can appreciate an at-a-glance visual indication of the operational status of the proper flow rate to the analyzer or sampling system. They can also see when an alarm/trip point has occurred. The flow switch’s set-point is conveniently user-settable via two push buttons accessible at the top of the unit or via the RS232C I/O port.
The Model FS10A is ideal for use with nearly all types of process and emissions sampling systems. That includes gas chromatographs (GCs), mass spectrometers, optical spectrometers, photometers and others. Standard configurations will accommodate standard 1/8, 1/4, 3/8 and 1/2 inch tubing as well as the SP76 (NeSSi) modular manifold.
Depending on the tube size, the FS10A Analyzer Flow Switch/Monitor operates over a wide flow range in air/gas. It can vary from 0.02 SCFH to 200 SCFH (10 cc/min to 100,000 cc/min). For water and liquids, the width ranges from 0.0.01 GPH to 12.00 GPH (0.70 cc/min to 750.00 cc/min). It accommodates wide turndowns with a ratio of up to 100:1.
The Model FS10A’s outputs include a 1A relay settable for NO or NC operation. It also comes with a user-settable for failsafe, hysteresis and/or time delay, and a 4-20mA analog output for trending.
In addition to its SIL-2 rating, the Model FS10A features global hazardous area operations approvals. Those approvals include ATEX, CE, CRN, EAC/TR CU, FM, FMc and IECEx for use in Div 2/Zone 2 environments.
Fluid Components International is a global company. It is committed to meeting the needs of its customers through innovative solutions to the most challenging requirements for sensing, measuring and controlling the flow, level and temperature of air, gases, and liquids.
