How to use a p&id template.
- 01Open the P&ID maker
Launch the diagram tool and choose a blank canvas or start from the provided three-tank overflow example.
- 02Place the three tanks
Drag tank symbols onto the canvas and arrange them at different heights to represent the gravity cascade.
- 03Connect the overflow lines
Draw pipes from the upper tanks to the lower tanks, adding check valves or control valves as needed.
- 04Add instrumentation and labels
Insert level sensors, temperature probes, and tags to fully document the system.
- 05Export or share
Download your diagram as PNG, SVG, or PDF, or share a live link for collaboration.
Questions about p&id templates
What is a three-tank gravity overflow system?
It's a setup where three tanks are arranged at different elevations so liquid flows from the highest to the lowest purely by gravity, often used for sequential processing or cooling.
How does gravity overflow work in a multi-tank cascade?
Each tank has an overflow outlet near its top. When the liquid level exceeds that height, it spills into the next lower tank, maintaining a constant level in the upper tank.
What are common applications of three-tank gravity overflow systems?
They are used in brewing (wort cooling), water treatment, chemical dosing, and any process requiring passive liquid transfer between stages without pumps.
Can I edit the example diagram to match my process?
Yes, the example is fully editable. Click 'Make your own' to load it into the editor, then modify tank sizes, pipe routes, labels, and instrumentation as needed.
