The Sauermann DBM 620C Air Flow Meter is a multipurpose electronic air balancing instrument primarily used for efficiently taking direct air volume readings from air vents.
The DBM 620C is supplied with base including temperature and humidity probe, pressure measuring unit, 610x610mm (2’x2′) hood including foldable frame and airflow straightener, 720x720mm (2.36’x2.36′) / 720x1320mm (2.36’x4.33′) / 420x1520mm (1.4’x 5′) / 1020x1020mm (3.35’x3.35′) hoods with foldable frames, frame rods with sheath, 2x80cm of silicone tube, calibration certificate and transport case.
Capture Hoods
The DBM 620C air flow meter comes in standard with a 2 x 2 ft (610 x 610 mm) hood. Hoods are airtight and has a transparent viewing window that allows the user to see through the vent to ensure the hood is in the proper position.
4 additional hoods:
- 3.35 x 3.35 ft (1020 x 1020 mm)
- 2.36 x 2.36 ft (720 x 720 mm)
- 2.36 x 4.33 ft (720 x 1320 mm)
- 1.38 x 4.99 ft (420 x 1520 mm)
Functions of the micromanometer housing
The electronic housing can be used alone to perform the following functions:
In air velocity and airflow:
- Choose between the Pitot tube, Debimo blades, coefficient or measurement grid Section selection
- Unit selection
- Point/point, automatic or automatic point/point average
- Manual compensation in temperature, automatic or manual compensation in atmospheric pressure
- Hold, minimum and maximum values
- Standardized airflow, K factor
In pressure:
- Manual or automatic auto-zero
- Unit selection
- Pressure integration (from 0 to 9)
- Point/point, automatic or automatic point/point average
- Hold, minimum and maximum values
Measurement grid
The measurement grid is attached to the base and measures 24 different points throughout the surface of the flow area. Measurement is performed using a differential pressure sensor calibrated in atmospheric pressure and temperature and compensated in temperature.
Autonomous micromanometer
Once removed, the measuring unit can be used as a micromanometer:
- Measure airflow in a duct using the Pitot tube attachment
- Silcone tubing allows technician to check for filter issues
Device positioning on the air vent
SmartKap mobile application will help you correctly position the hood on the air vent:
- Select the correct air vent type, OR
- Create a customized air vent if required
- Follow the instructions for a perfect fit!
Operating principles
The DBM 620C housing communicates with the smartphone or tablet via Bluetooth®. This allows measured values reading and viewing of reports directly on your mobile device screen, via the dedicated SmartKap mobile application.
