Abstract
A fluid pressure and temperature sensing probe assembly for a mass flow measurement system comprising, a tubular body, a portion of which is adapted for insertion into the fluid flowing in a confined conduit, and having, within the body, a pair of separated plenums. Openings are provided in the tubular body which expose the respective plenums to high and low fluid pressures in the fluid flow. An electrically responsive temperature sensor, having an electrical signal output, is disposed within the tubular body of the probe. A pressure transducer, in fluid communication with the plenums, converts the fluid pressures in the plenums to at least one electrical signal representative of the difference between the high and low fluid pressures. A transmitter transmits the electrical signal from the pressure transducer and the electrical temperature signal to a remote location.
