A system and method for determining when a sand separator should be purged to remove solids from the sand separator. The system can include an acoustic sensor which detects the frequency of audible sound coming from the inner chamber of the vessel and generate a signature signal representative of the frequency of audible sound. There is a processor connected to the acoustic sensor and configured to compare the signature signal with a set frequency range of audible sound which in turn generates a signal indicating when the signature frequency and the set frequency are in overlapping relationship.

A system for controlling sand discharge from a plurality of sand separators each of which has a dump line and an actuated valve apparatus in the dump line. There is a first controller which is operatively connected to the actuated valve assemblies and is configured to open one of the actuated valve assemblies in response to a parameter such as internal pressure in the sand separator. There is a second controller which is connected to the first controller and which is also connected to an actuated discharge valve in a common discharge line to which all of the dump lines are connected. On a command from the first controller to the second controller that a selected one of the actuated valve assemblies is opening, the second controller opens the discharge valve.
