Right Answer is:

A piezometer tapping

SOLUTION

Static pressure is the pressure in a flowing fluid. A common way to measure static pressure is to drill a small hole in the wall of a pipe and then connect a piezometer or pressure gauge to this port. This port is called a pressure tap or piezometer tapping. The reason that a pressure tap is useful is that it provides a way to measure static pressure that does not disturb the flow.

‘When measuring the static pressure in a pipe, it is often desirable or necessary to drill several static pressure taps and connect them with a tube that goes around the pipe. The tube is called a piezometer ring. This method will account for imperfections in the pipe wall.
