A field generator for generating an electrostatic field within a liquid is provided with a cylindrical body having a protective non-conducting coating covering a major portion of its length, a first boss comprising a mounting boss enclosing one end of the body in protective sealing relation therewith and a second protective boss similarly mounted in protective sealing relation at the other end of the body independently of the first boss to provide a rodless field generator construction. In one embodiment the field generator is employed in combination with an enclosing pipe for conducting a flow of liquid past the field generator, the pipe being secured in axially constraining relation with at least one of the end bosses.
