1. A method of making a sensor assembly for a vortex flowmeter of the type having a flowtube having a flowtube wall defining a passage for flow of a process fluid through the flowtube, a bluff body in the flowtube for generating vortices, and a sensor for detecting vortices formed by the bluff body, the sensor assembly being configured to extend into contact with the process fluid through a process penetration opening, the method comprising:
securing a vortex sensor to a vortex sensor housing, the vortex sensor housing being secured to a sensor body configured to seal the process penetration opening to limit flow of process fluid from the passage out of the flowmeter through the process penetration opening; securing a pair of pressure-responsive diaphragms to the vortex sensor housing such that the pressure-responsive diaphragms face outwardly from opposite sides of the vortex sensor housing and such that the vortex sensor is positioned to detect motion of at least one of the pressure-responsive diaphragms to detect vortices formed in the process fluid; making a mounting hole in the sensor body spaced apart from the vortex sensor housing; securing a temperature sensor housing to the sensor body through the mounting hole; and inserting a temperature sensor in the temperature sensor housing for sensing a temperature of the process fluid. |
