摘要：A testing apparatus comprising: a chamber (5) having an inlet (6) and an outlet(16) ; a measuring device (4) , at least a part of which is provided within said chamber;wherein the inlet is arranged to direct fluid onto said part of the measuring device withinthe chamber in order to clean the measuring device during start up. Thus the density orviscosity of drilling mud may be continuously monitored. Preferred embodiments includean outlet valve such as a ball valve (7) with a bore defined therein. The bore allows fluidto flow therethrough even in a valve 'closed' position and so generates the preferredback pressure whilst minimising the risk that the valve will block. A pressure activateddrain valve (9) is also provided to substantially empty the chamber when not in use. Whenthe apparatus is reactivated, an inlet tube is adapted to jet air and then fluid at themeasuring device in order to remove debris therefrom. Thus the apparatus has theimportant benefit of self cleaning during start-up.
