1. A method of cleaning an internal cavity of a pressure instrument comprising a Bourdon tube pressure gauge, the method comprising:
mounting the pressure instrument on a rotation unit in a housing;
fluidly connecting the internal cavity of the pressure instrument with an input fluid container;
introducing a cleaning fluid from the input fluid container into the internal cavity;
rotating with the rotation unit, the pressure instrument relative to the housing about an axis of rotation that passes through and is generally perpendicular to a front faceplate of the pressure instrument;
agitating the cleaning fluid in the internal cavity;
fluidly connecting the internal cavity of the pressure instrument with an output fluid container; and
evacuating the cleaning fluid from the internal cavity into the output fluid container
wherein the rotation unit comprises a rotatable mounting surface for mounting the pressure instrument thereon and a motor configured to rotate the mounting surface and the mounted pressure instrument about the axis of rotation that passes through and is generally perpendicular to the front faceplate of the pressure instrument.
