Abstract
A sensor arrangement for a vortex shedding flowmeter having a flowmeter housing which is exposed to a flowing fluid in a fluid space on one side of the housing, comprises a sensor housing which is connected to the flowmeter housing and which defines an internal sensor space. A sensor beam is connected to the housing and has a first portion extending into the sensor space with a second portion extending through the flowmeter housing into the fluid space. A diaphragm resiliently carries the beam for movement in response to the passage of vortices in the fluid space. A mounting bracket is detachably connected to the sensor housing and carries a sensor element. The sensor element is operatively connected to the first portion of the sensor beam and can be easily engaged and disengaged thereto when the mounting bracket is to be removed. In this way if the sensor element fails, it can be replaced without stopping the flow of fluid or disturbing the sensor beam.
