The scenario
A swimming pool requires continuous water recirculation and filtration to maintain water clarity and hygiene. The circuit draws from the pool basin, passes through a centrifugal pump and sand filter, and returns the treated water via a flow control loop.
What is in this drawing
Read the decisions behind it.
01
Use a tank_atm to represent the pool basin as the suction source and return sink.
02
Include a flow transmitter (FT-101) and flow indicating controller (FIC-101) to regulate recirculation rate through a diaphragm-actuated control valve.
03
Specify process line sizes and service tags for clarity.
Suitable for documenting swimming pool mechanical rooms, water parks, or aquaculture recirculation systems where a P&ID is needed for control and maintenance.
