Luftventil Durchflussmessgerät
A compact cone-type airflow measurement device for direct supply and extract volume-flow checks at circular disc valves and small ventilation terminals.
- Full-flow capture at circular air valves.
- Integrated straightener controls swirl effects.
- Compact bidirectional direct-flow display.
Produkteinführung
This device seals a shaped low-resistance cone around a circular air valve and guides the full stream through an integrated flow straightener and sensing grid. The detachable digital meter displays supply or extract volume flow without requiring a separate area calculation. Its compact mouth is easier to position on small ceiling and wall terminals than a full-size capture hood.
Key Features
Integrated straightener reduces swirl-related measurement variation.
Reversible sensing supports supply and extract terminals.
Direct volume-flow display removes manual area conversion.
Soft perimeter seal limits bypass around the valve face.
Compact handheld format suits congested ceiling locations.
Kunden Produktbedenken
Circular air valves generate curved and swirling flow patterns that are difficult to quantify with a point sensor and often sit where a full-size hood cannot be positioned.
Point velocity readings are unreliable in the swirling flow near a disc valve.The cone captures the full stream and the straightener conditions it before measurement.
Air bypass around the measuring device understates terminal flow.A compliant perimeter gasket seals against the surrounding ceiling or wall surface.
Large capture hoods are awkward around closely spaced ceiling services.The compact circular cone reaches small valves with less clearance.
Supply and extract checks may otherwise require different setups.Bidirectional sensing reports both flow directions through the same cone.
