ABSTRACT:
Liquid is removed from a remote location, with control of the system responsive to the supply of the liquid to be removed. Control is accomplished without the need for electrical devices at the remote location by means of a valve in the remote location in the conduit circulating a powering fluid to a pump at the remote location, and the sensing of the accompanying changes in flow or pressure in the powering fluid conduit or output conduit.
