Orifice Meter and Pitot Tube

The orifice meter is a device (cheaper than venturimeter) used for measuring the discharge of the liquid flowing through a pipe. It works on the same principle as that of venturimeter.

The pitot tube is a small open tube bent at right angle. It is used to measure the velocity of flow at the required point in a pipe. It is determined by measuring the rise of liquid in a tube.
