Fluid Components FlexSwitch FLT93S flow switch

Thursday, 18 March, 2010 | Supplied by: AMS Instrumentation & Calibration Pty Ltd


The FlexSwitch FLT93S flow switch from Fluid Components can be used by process and plant engineers who need to monitor fugitive emissions from compressors, pressure relief valves, pumps and other gas flowing components.

The switch’s high sensitivity and ability to detect and alarm on very low flows offers fast response leak monitoring and detection of gas flows. It provides early warning and process shutdown signals that can prevent damage to expensive components and processes as well as reduce the probability of accidents and government incident reporting.

It is a suitable plant preventative maintenance and safety tool, helping to ensure gas flow system components are operating correctly.

It is an easy-to-install, insertion-style instrument that includes dual 6A relays, which are fully user settable for any HI, LO, HI/HI or LO/LO detection and trip scenario. It operates over a wide gas flow sensitivity range from 0.08 to 37 SMPS. Accuracy is ±0.5% of reading or 0.06 NMPS. The standard switch withstands operating temperatures from -40 to 177°C, and an optional configuration is available for temperatures from -73 to 454°C. The full instrument has the approvals of FM, CSA, ATEX and IEC for hazardous, Ex environments and has a SIL 2 compliance rating.

With its thermal dispersion mass flow sensor, the switch features built-in temperature compensation, which ensures repeatable and reliable operation, even in extreme environments.

A wide selection of standard and custom process connections can be provided with the FLT93S switch. The electronic control circuit can be integrally mounted with the sensing element, or it can be located in a remote location. The standard enclosure is a rugged aluminium alloy and IP66 rated, with stainless steel or fibreglass enclosures optionally available.
