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

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.

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