<p>The present probes are miniaturized, total pressure and total temperature, probes (100) able to measure in wet gas conditions, two phase flow, inside pipes or compressor. When measuring in wet gas conditions, the pressure and temperature probes are significantly affected by the presence of liquid phase. This causes errors in the measurement of the gas properties or doesn't allow the measurement. This problem is solved by letting the probe measure accurately also 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 (100), beside the purging of the liquid collected, has a miniaturized cup (1) 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.</p> |
