Abstract
A replaceable antenna assembly for use with a piston accumulator configured for supplying fluid to a hydraulic cylinder is provided. The antenna assembly includes a hollow manifold for flow of fluid and an antenna connected into or onto the manifold for emitting and receiving electromagnetic waves. The hollow manifold is connectable to and configured to be in fluid communication with both the piston accumulator at one end and a pressure line at the other end. The pressure line is connectable to an external high pressure gas bank. The antenna assembly further includes at least one first bore for transferring signals to and from the antenna and at least two fluid channels symmetrically displaced around the circumference of the antenna, thereby ensuring that most of, or all, fluid flows on the radial outside of the antenna during use.
