How to Setup Dwyer 477AV Handheld Digital Manometer for Air Flow
This post explains how to set up and use the Dwyer Series 477AV Digital Manometer for air flow measurement. By the end of this blog post, you'll have a comprehensive knowledge to incorporate the 477AV and related tools into your practice and testing regime. The attached YouTube video is featuring Santiago, a Senior Applications Engineer at Dwyer Instruments, who demonstrates how to set up the 477AV, establish flow mode, select units, adjust diameter and K factor, connect with the 167 pocket-sized pitot tube and 160 G averaging airflow grid, take readings, adjust K factor, connect with the 160 G, and more. NIST CALIBRATION options is available in Product Configurator. Traceable Certificate is available with SKU number 477AV-1-NIST.
Features
- Calculates and displays air velocity and volumetric air flow
- Rugged aluminum case protects instrument from damage during transport/use
- Nine selectable English and metric engineering units
- Large, easy to read display with backlight for use in dark areas
- Stores up to 40 readings with minimum, maximum and average statistics
Applications
- Air flow monitoring, when used with a Dwyer pitot tube (sold separately)
- Duct static pressure
- Commercial air balancing
- Building-zone pressure
1. Software Set-Up of the 477AV Digital Manometer for Air Flow Measurement:
To configure the 477AV Digital Manometer for air flow measurement, the first step is entering the menu and changing the mode to "Flow" (FL o). After that, also select the units of your preference (CFM, in this case) and modify the diameter of the circle in the corresponding cross-sectional area. Finally, set the K factor of the pitot tube.
2. Utilizing a 167 Pocket-Sized Pitot Tube with 477AV Digital Manometer:
To use the 167 Pocket-Sized Pitot Tube with a 477AV Digital Manometer, it is essential to ensure that the high port goes to the total port. After connecting to the system, the device should be zeroed and the airstream turned on. Taking accurate measurements is now possible.
3. Connecting a 160 G Averaging Airflow Grid with 477AV Digital Manometer:
In order to use the 160 G Averaging Airflow Grid with a 477AV Digital Manometer, it is necessary to adjust the K factor to match the air grid. Next, connect the tubing with the positive port going to the total and the negative to the static. Then, zero the unit, turn on the airstream and measure the flow. Don't forget to disconnect the tubes after use and you will get accurate readings.
FAQ
Q: What is the 477AV Digital Manometer?
A: The 477AV Digital Manometer is a device used to measure the airflow for certain applications by Dwyer Instruments.
Q: What is the purpose of programming the 477AV into flow mode?
A: Programming the 477AV into flow mode allows the user to read out the airflow measurement in CFM.
Q: What items are needed to measure the airflow with the 477AV device?
A: To measure the airflow with the 477AV device, you will need a 167 pocket-sized pitot tube and a 160G averaging airflow grid.
Q: How do you zero the 477AV?
A: To zero the 477AV, you will need to turn the airstream off and the 477AV will automatically zero itself.
Q: How do you use the 477AV with the 160G grid?
A: To use the 477AV with the 160G grid, you will need to adjust the K-factor to match the air grid, connect the positive port to the total and the negative port to the static, then extend the pull upward to take an accurate measurement.
