P&ID diagrams do not have a compass in the left upper corner.

Explanation:
P&ID diagrams often include a compass rose or north arrow to establish orientation. Placing it in the upper corner, commonly the left, gives readers a quick reference to align the diagram with site plans, isometrics, and instrument loops. This orientation helps interpret piping directions, equipment locations, and flow paths consistently across drawings used in design, construction, and commissioning. Because of this, the statement that P&ID diagrams do not have a compass is not accurate in the usual practice; many standards or projects include a compass, though some drawings may omit it as an exception.
