Abstract
A sensor assembly for detection of fluid flow signaling over a tubular conveyance. The assembly may be employed for activation of a variety of different downhole actuators such as firing heads for perforating guns or hydrostatic set modules for packer deployment. The assembly is configured with a flow translation device which is disposed in a manner exposed to fluid flow directed through an oilfield tubular coupled to the assembly. Thus, a detector coupled to the translation device may obtain mechanical data from the device which is reliably indicative of the flow, irrespective of the physical nature of the flow itself. As such, enhanced reliability for subsequent actuator firing based on the flow signaling may be achieved.
