Enhanced Rupture Disc Burst Detection
Elfab’s Exd-approved Flo-Tel burst detection system

With ever-increasing safety standards and environmental considerations for process plants in today’s demanding climate, the need for burst detection alongside rupture (bursting) discs is vital to quickly identify when a disc has burst. Customers are now seeking increasingly advanced systems to provide this detection without stretching budgets.

For more than a decade Elfab’s Flo-Tel technology has offered customers a cost-effective ATEX Zone 1 compatible, non-invasive, failsafe, and re-useable burst detection system. At a time when stringent safety standards are of utmost importance, Flo-Tel offers advantages from triggering alarms to the shutting down of a process. IECEx approval also certifies the Flo-Tel system for use internationally in the most hazardous of environments. Following the original Flo-Tel technology, Elfab launched its Exd-approved version, negating the need for intrinsically safe barriers and interfacing directly with the customer remote terminal unit to reduce installation costs.

In line with recent developments within high integrity industries, Elfab has further quantified the reliability of its detection systems in hazardous processes by attaining Safety Integrity Level (SIL) ratings for its Flo-Tel and Flo-Tel XD products. Using generally recognized models for risk assessment and risk reduction such as SIL, engineers are now finding this an effective way to improve a systems overall safety. The oil and gas, and chemical and pharmaceutical industries in particular have seen the advantage of replacing traditional burst detection systems with their non-invasive, SIL-rated counterparts. When upgrading their pressure relief devices and associated detection, many plants have witnessed an end to the spurious alarms and subsequent downtime previously caused by unreliable or easily-damaged membrane-type burst detectors. Cost savings of tens of thousands of pounds are being realized.
