## Symbol convention

Convention: IEC
Form: Gas-flow actuation qualifier
Autodesk IEC-60617 Symbol Preview — Operating-device and function qualifiers; vendor family reference, not certified IEC geometry or database identifier.

A gas-flow qualifier identifies operation responding to gas movement.

## What it represents

A gas-flow qualifier identifies operation responding to gas movement. Gas-flow actuation identifies the moving-gas condition used by the device. It is not equivalent to a static pressure condition, even where both participate in one ventilation or process sequence.
Document the monitored path and the resulting electrical input. A separate description is needed for any alarm delay, operating threshold or fan permissive.

## How to read it

- Distinguish the gas process from any adjacent liquid-flow or pressure measurement.
- Gas flow and gas pressure are different process quantities.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Distinguish the gas process from any adjacent liquid-flow or pressure measurement.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

Gas flow and gas pressure are different process quantities.
