Abstract
A subterranean solids fallback protection device (160) has a differential pressure measurement system configured to determine the quantity of solids accumulated within the device based on the pressure differential across the device during operation. A first pressure gauge (170) is positioned above the solids fallback protection device, and a second pressure gauge (170) positioned below the solids fallback protection device, and the differential pressure measurement system includes these gauges for measuring pressure above and below the device.
