    Manometer

    Introduction Manometer - Simple Manometer - Micro Manometer - Vertical Tube Macro Manometer - Inclined Tube Micro Manometer - Differential Manometer - Inverted Differential Manometer

    Manometry refers to the measurement of pressure by comparison to the hydraulic pressure produced by a column of liquid. A Manometer is a device to measure pressures. The manometer is one of the most elementary measuring devices imaginable.

    Strictly speaking, a manometer is a improved form of a piezometer


    With the help of a manometer, we can measure comparatively high pressures and negative pressures also.

    Simple Manometer Micro Manometer Differential Manometer Inverted Differential Manometer

    A simple manometer is a slightly improved form of a piezometer tube for measuring high as well as negative pressures.
    A simple manometer, in its simplest form, consists of a tube bent in U-shape, one end of which is attached to the gauge point and the other is open to the atmosphere.

    The liquid used in the bent tube or simple manometer is generally, mercury which is 13.6 times heavier than water. It is suitable for high pressure also.

    It is a modified form of manometer, in which cross sectional area of one of the limbs is made much larger than that of the other limb.
    A micro manometer is used for measuring low pressures, where accuracy is of much importance.

    There are many types of micro manometers, yet the following two types are important. Vertical Tube Micro manometer
    Inclined Tube Micro manometer

    A vertical tube micro manometer connected to a pipe containing light liquid under a very high pressure. The pressure in the pipe will force the light liquid to push the heavy liquid in the basin downwards.

    12

    Due to larger area of the basin, the fall of heavy liquid level will be very small. This downward movement of the heavy liquid , in the basin, will cause a considerable rise of the heavy liquid in the right limb.

    13

    Sometimes, the vertical tube of the micro manometer is made inclined. An inclined tube micro manometer is more sensitive than the vertical tube type. Due to inclination, the distance moved by the heavy liquid, in the narrow tube, will be comparatively more, and thus it gives a higher reading for the given pressure.

    It is a device used for measuring the difference of pressures, between two points in a pipe, or in two different pipes. A differential manometer, in its simplest form, consists of a U-tube containing a heavy liquid whose two ends are connected to points, whose difference of pressure is required to be found out.

    15

    It is a particular type of differential manometer, in which an inverted U-tube is used.


    An inverted differential manometer is used for measuring difference of low pressures, where accuracy is the prime consideration.
