One or more rods are employed in the flow passage of the above-described flowmeter as the drag-producing bluff body. Conveniently, the rods can also serve as probes for sensing the pressure in the flow passage. In the preferred embodiment, one rod is radially oriented upstream of the restriction and another rod is radially oriented at an angle to the first rod within the restriction. The rods have hollow interiors connected to a DELTA P transducer. The first rod has a chamfered end facing upstream. |
