Abstract
A flushable manifold for diaphragm protected components of a pressure transducer for sensing a flow of fluid comprises a housing having a recess therein and a diaphragm of flexible material over and closing the recess. Inlet and outlet passages communicate with the recess adjacent to and on opposite sides of its periphery, such that fluid introduced at the inlet flows through the manifold to the outlet, with the presence of fluid pressure within the manifold being detected in response to outward deflection of the diaphragm. To facilitate cleaning the manifold of fluid of one type in preparation for receiving fluid of another, one or more channels are formed in the housing within the recess in communication with the inlet and extend toward peripheral side areas of the recess to direct flushing media introduced at the inlet across all of the surfaces of the manifold and to the outlet to thoroughly clean the same. Absent the channels 'dead spaces' would exist in the manifold and the flushing media would tend to follow a straight line path of least resistance between the inlet and outlet, thereby failing to satisfactorily clean side areas of the manifold.
