There is disclosed herein a wellbore servicing method comprising: activating a wellbore servicing apparatus (200a, 200b or 200c) by transitioning the wellbore servicing apparatus from a first mode to a second mode, wherein the wellbore servicing apparatus is configured to transition from the first mode to the second mode at a delayed rate and to cause an elevation of pressure within a flowbore of the wellbore servicing apparatus; and detecting the elevation of the pressure within the flowbore, wherein detection of the elevation of the pressure within the flowbore for a predetermined duration, to a predetermined magnitude, or both serves as an indication that the wellbore servicing apparatus is transitioning from the first mode to the second mode. |
