Measuring moisture in Natural Gas and LNG at pressure only invalidates traceability and speeds up damage to sensors. There are several corellations converting a known (traceable)water content to (displayed)pressure dewpoint. Measuring at atmospheric presure is the only traceable and direct validation method against existing Standards. It's traceable, it reduces uncertainties and lowers running costs by extending sensor life. If we are seeking Traceability and measuring in ppm ( a mass concentration term)then surely this is the way to go to gather more reliable data?
