manometer
what are the advantages of a u-tube manometer than a piezometer
the most common type of manometer are u-tube type,inclined and the cistern type of manometer
the fluid level in manometer will rise through an inclined line rather than vertical line. So when ever there is slight variation in pressure the manometer (inclined) will be able read it. The pressure drop is given by P=h*density*g*sin(angle).
By cathetometer (precise but expensive), or by inclined tube method
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.
it is simple to construct,cheap,very accurative
A well-type inclined manometer is a device used for measuring small pressure differences in fluids. It consists of a U-shaped tube partially filled with a colored liquid, with one leg inclined at an angle to increase sensitivity. The liquid in the well acts as a reference point for measuring pressure differentials.
I think you're looking for U-Tube Manometer
the advantage is the design is complicated
Manometer.
An inclined manometer is a device used to measure pressure differences in a system. It consists of a U-shaped tube partially filled with a liquid (like mercury or water) with one end connected to the system being measured. The difference in liquid levels in each arm of the tube is proportional to the pressure difference between the two points. The angle of inclination allows for a more sensitive measurement of small pressure differences.
