A manometer is a device that is used to measure the pressure of a fluid. The U-shaped glass tube is partially filled with a liquid, usually Mercury. The difference between the height of the mercury corresponds to the difference between the pressure of the fluid in the container and the atmospheric pressure.
An inclined manometer is used to measure low-pressure differences accurately because the incline amplifies the liquid column movement, making small changes more visible. It is also used when space limitations prevent the use of a vertical manometer setup.
To use an inclined water manometer for air conditioning, you would first connect one end of the manometer tube to the air conditioning system at a pressure measurement point. Then, you would position the manometer at an incline to measure the pressure difference between the two ends of the tube. This pressure difference can help determine if the system is operating within the desired pressure range.
To set up a manometer, first ensure that it is securely mounted in a vertical position. Fill the manometer with a fluid, typically mercury or water, making sure there are no air bubbles. Connect the manometer to the system you want to measure the pressure of, and then observe the height difference of the fluid levels in the manometer to determine the pressure.
To calculate CFM (cubic feet per minute) using a manometer, measure the pressure difference across a restriction in the airflow system. Use the manometer reading and the area of the restriction to determine the velocity pressure. Then, use the velocity pressure to calculate the airflow in CFM using the formula CFM = (Velocity Pressure * Area of the Restriction) / 4005.

Electrical manometer is an electronic manometer use to record pressures between two points. It is commonly used in recording pressure in bridges.

To effectively use a manometer to measure pressure, first ensure the manometer is properly calibrated and zeroed. Next, connect one end of the manometer to the system or device where pressure is to be measured. The other end should be open to the atmosphere. The difference in fluid levels in the manometer will indicate the pressure. Read the measurement from the scale on the manometer to determine the pressure accurately.

To determine pressure
A manometer measures pressure. The units depend on the type of manometer and how it's calibrated. Units include psi, barr, Torr, atm, pascals, and kilopascals.

A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
