A filtration and monitoring system. An inlet pipe provides fluid to a filter block chamber and has an inlet valve located therein configured to shut off the flow of the fluid through the inlet pipe. A filtered fluid conduit fluidically connects the filter block with the monitoring device. The outlet axis of the outlet pipe in the filter chamber is offset from the inlet axis of the inlet pipe such that the fluid undergoes a change of direction while passing through the filter block chamber thereby causing turbulent flow within the filter block chamber to reduce the buildup of filter cake on the filter element. Closing the inlet valve block, results in a back-flushing flow of fluid through the filter element from a pressure accumulator located in the filtered fluid conduit.
