Frequently Asked Questions

Does AI use standard P&ID symbols?

Yes! AI matches symbols from a specialized P&ID icon pack that includes standard ISA symbols for valves, instruments, vessels, pumps, and other process equipment.

Can it generate instrument tag numbers?

AI generates proper instrument tags following standard notation (e.g., TT-101 for temperature transmitter, FCV-102 for flow control valve) based on your process description.

What valve types are supported?

AI can generate gate valves, globe valves, ball valves, butterfly valves, check valves, control valves, pressure relief valves, and more with proper P&ID symbols.

Can I add control loops to the diagram?

Yes! Describe your control requirements and AI creates proper control loops with sensors, transmitters, controllers, and final control elements connected correctly.

How complex can the P&ID diagrams be?

AI can generate P&IDs with dozens of equipment items, multiple control loops, and complex piping networks. Regenerate with more detailed prompts to iteratively build complex systems.

Is the AI P&ID generator free?

MockFlow includes AI credits with all plans. For unlimited usage, connect your own Claude (via MCP) or ChatGPT (via GPT Actions) API — then you can generate P&ID diagrams with no limits at all.
