1. Dixon was an expert on the theory and use of manometers . 2. Using the manometer he tested those hypotheses one by one. 3. The pressure drop across the bed is measured by a similar manometer . 4. A manometer uses the weight of the liquid to indicate air pressure. 5. This pressure can easily be measured with a manometer . 6. Tsien's experiments included plotting of pitot pressures using mercury-filled manometers . 7. Wilms is also credited for developing a manometer for measurement of cerebrospinal fluid pressure. 8. The instrument would be calibrated against a manometer , which would be the calibration standard. 9. The hydrogen was inserted by squeezing the balloon while monitoring the pressure on a manometer . 10. Using his Warburg manometer , he mixed a slice of liver with purified ornithine and citrulline.
