Flo-Tel burst detection system

Non-invasive, ATEX approved magnetic burst detection

Flo-Tel offers a practical, reusable solution for detecting when a rupture disc has functioned (burst).

Operating on a simple reed switch and magnet technology, the sensor fits into a holder with a magnet on the rupture disc. When the rupture disc bursts, the disc with its magnet arc away from the sensor, giving an open circuit signal.

Flo-Tel is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion. This feature also eliminates leak paths and the risk of false alarms associated with traditional membrane-type detection systems. After rupturing, the disc is the only element that needs replacing, which eliminates the need for expensive re-wiring costs and maintenance planning

This burst detection system is intrinsically safe, and when used in combination with an Elfab rupture disc, offers industry-leading SIL ratings.
