A fluid flow monitor has two spaced annular electrically conductive support members with an annular insulating spacer member between them. A conductive member extends diametrically across from one side of one supporting member to the other side of the other supporting member. The ends of the conductive member are releasably connected to the support members. At one end the conductive member is pushed under a strap, the end being pulled out on deformation of the conductive member on occurrence of fluid flow for example when the rupture disc bursts. If otherwise undamaged, the monitor can be reset by repositioning the conductive member and pushing the end back under the strap. Electrical terminal are connected to the support member.
