CHAPTER 4 1946- Guide In steam measurement, a constant head of water is maintained, over each, leg of the manometer by means of condensing chambers, in order to keep the heat of the steam away from the meter. ' As the mercury level fluctuates, the difference in head as recorded on the chart, therefore, is not that due to mercury alone, but to mercury minus an equivalent head of water.
