ABSTRACT:
Apparatus and method for detecting the presents of an interface between two fluids with a conventional interface detection apparatus, located remote from the interface, in a tube are disclosed. The apparatus and method utilize a driving fluid introduced into the tube to cause one or the other of the fluids forming the interface to flow from an end of the tube through the tube to the remote detection apparatus, permitting the latter to test the fluid in the tube to determine whether the interface is above or below the end of the tube.
