  • Manometer having dual pressure sensors
    Patent number: 6510741
    Abstract: A manometer for measuring fluid pressure having a first pressure sensor and a second pressure sensor that is inverted with respect to the first pressure sensor. The first pressure sensor generates a first electrical output signal corresponding to a fluid pressure measured by a first diaphragm of the first pressure sensor. The second pressure sensor generates a second electrical output signal corresponding to a fluid pressure measured by a second diaphragm of the second pressure sensor. The first and second electrical output signals are combined into a combined electrical output signal. False readings of a change in/pressure measured by the first pressure sensor and measured by the second pressure sensor in each of the first and second electrical output signals, due to movement of the manometer, are cancelled by one another in the combined electrical output signal to provide an accurate pressure measurement regardless of movement of the manometer.
