Abstract
A combined temperature and pressure sensing probe assembly for a flow measurement system comprising a body, a portion of which is adapted for insertion into fluid flowing in a confined conduit, such as a pipe. Within the body are separated plenums which are exposed respectively to high and low fluid pressures in the flow. A manifold block is that portion of the body which is disposed outside of the pipe containing the fluid flow. Along with valves and fluid conveying channels, the block is equipped with a duct for carrying electrical conductors and also contains a traversing bore which is aligned with the body and is in communication with the conductor carrying duct. An electrically responsive temperature sensor is disposed within or formed from the body. Conductors from the temperature sensor are directed from the manifold'"'"'s bore through the connecting duct to a point exterior of the manifold.
