Abstract: The present probes are miniaturized, total pressure and total temperature, probes able to measure in wet gas conditions, two phase flow, inside pipes or compressor. When measuring in wet gas conditions, the probe measures accurately with a defined amount of liquid phase. Differently from standard probes, such probes are able to generate a gas expansion on the external side of the cup. This guarantees the appropriate purging of the liquid fraction of the flow from the cup, letting the total pressure measurement of the gas. The total temperature probe, beside the purging of the liquid collected, has a miniaturized cup in order to protect the measuring element from the direct impact of the liquid droplets. This permits to measure the total temperature of the gas, without influence of the liquid fraction of the flow.
