à Mount VEGADIF 65 below the measurement loop so that the
effective pressure lines are always filled with liquid and gas
bubbles can bubble up to the process line
à For measurements in products with solid content such as e.g. dirty

recommended to enable collection and removal of debris and
sediment.
