ABSTRACT:
A bluff body flowmeter, including a bluff body having a planar base surface portion disposed normal to fluid flow and a pair of converging downstream surfaces, is provided with a fluid flow channel in the base surface portion, a sensor in the channel and a shield which partially covers the channel and protects the sensor from impact damage. The shield and channel are mutually adapted so that fluid flow through the channel is substantially unidirectional. In one embodiment at least that portion of the shield which covers the channel is shorter than the channel thus forming a rectangular notch which acts as a fluid flow entrance port.
