The document presents information about manometers, including their history, types, applications, advantages, and disadvantages. Manometers are devices used to measure pressure at single or multiple points in pipelines by balancing fluid columns. The oldest type is the liquid column manometer invented by Evangelista Torricelli in 1643. Common types include simple manometers, differential manometers, U-tube manometers, and single column manometers. Manometers have applications in measuring groundwater pressure and fluid pressure. Their advantages are low cost, simple construction, and high accuracy relative to cost. Disadvantages include being large and bulky, requiring leveling, and lack of portability.

3. TOPIC:
 Applications Of Manometr

4. HISTORY:
Many instrument have been invented to measure pressure,
with different advantages and disadvantages.
The oldest type is the liquid column (a vertical tube filled with mercury)
manometer invented by Evangelista Torriceli in 1643.

5. MANOMETRY:
Manometer is a device used to measure pressure at
a single or multiple points in a single or multiple pipelines,
by balancing the fluid column by the same or another
column of fluid.

6. TYPES OF MANOMETR:
 Simple Manometer
 Differential Manomete

7. APPLICATION:
Piezometer :
An instrument for measuring the pressure of a liquid or gas, or something
related to pressure (such as the compressibility of liquid). Piezometers are often
placed in boreholes to monitor the pressure or depth of groundwater.
U-tube Simple Manometer:
U-tube manometer is a simple mano metric device used
to measure pressure at a point in a fluid, by balancing the fluid column by the same
or another column of fluid. It has a glass tube bent in “U” shape with some amount of
same or other type of fluid, called mano metric fluid like mercury.

8. Single column/Micro manometer:
Single column manometer is a modified form of a U-tube
manometer in which one side is a large reservoir and the other
side is a small tube, open to the atmosphere.
There are two types of single column manometer:
1- Vertical single column manometer.
2- Inclined single column manometer.

9. ADVANTAGES:
Low cost.
Simple construction.
Time tested in applications.
Availabillity in wide variety of ranges , including very high ranges.
High accuracy, especially in relation to cost.

10. DISADVANTAGES:
Large and bulky.
Need for leveling.
Lack of portability.
No over range protection.
Condensation may present problems .
