Leak detecting flow switch

The FlexSwitch FLT93S Flow Switch is designed to monitor fugitive emissions from compressors, pressure relief valves, pumps and other gas flowing components. Its 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 shut-down signals that can prevent damage to these components and their processes as well as reduce the probability of accidents and government incident reporting. The switch 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 gas flow sensitivity range from 0.08 to 37m/s. Accuracy is ±0.5 percent of reading or 0.06m/s. The device withstands operating temperatures from -40 to 177°C, and an optional configuration is available for temperatures from -73 to 454°C. The instrument has global agency approvals of FM, CSA, ATEX and IEC for hazardous, Ex environments and has SIL 2 compliance rating.
