🔍 Key Concepts

• Understand the difference between normally open (NO) and normally closed (NC) contacts in schematic symbols • Recognize how a flow switch is indicated compared to other process switches (pressure, level, temperature)** in the illustration • Match the physical paddle-type flow switch shown in section E with the correct symbol (1–14)

💭 Think About

• First, identify which picture (A–F) shows a flow switch, then look for a unique feature in that device (for example, a paddle or element in the pipe) • Compare the special mark used in that device’s symbol (triangle, circle, zig‑zag, etc.) with the symbols 1–14 and decide which one represents the same type of process influence • Determine which of those candidate symbols shows contacts open in their normal (no‑flow) condition rather than touching

✅ Before You Answer

• Verify which graphical shapes in the lower row belong to flow versus pressure/temperature/level switches by matching them to the top-row devices • Confirm that in a normally open contact symbol, the line representing the moving contact is not touching the fixed contact when in the normal state • Double‑check that the symbol you choose both (1) matches the flow switch device and (2) shows an open gap between contacts in the normal position
