"With precise measurement of air flow, the DBM620 cap-type air flow meter, leveraging the pressure difference principle and intelligent sensors, plays a pivotal role in ventilation system testing and industrial environment monitoring. Mastering the correct usage method, from understanding the equipment composition to grasping the operational essentials, ensures accurate data. Regular maintenance further extends the equipment's lifespan, meeting the needs of diverse scenarios."

1. Equipment composition: The DBM620 cap-type air flow meter consists of several main parts. Firstly, the cap part, which is used to cover the ventilation opening to collect air. Secondly, the sensor unit, responsible for detecting air flow velocity and temperature. There is also the display unit, used to show the measurement results. The equipment is usually equipped with battery power supply, ensuring operation even without an external power source. It may come with a data recording function, allowing users to save multiple measurement data.
2. Operating Principle: This device operates based on the pressure differential principle. When air flows through the cap, it induces pressure changes on the sensor. The sensor converts the pressure signal into an electrical signal, and then calculates the air volume through internal computation. Depending on the design, the device may utilize a thermal sensor or a pitot tube sensor. The measurement results are displayed on the screen, typically in cubic meters per hour or similar standard units.
3. Operating Steps: When using the DBM620 cap-type air volume meter, follow the steps below. Ensure the device is fully charged and check if the display screen is normal after turning it on. Align the cap with the ventilation opening, ensuring a good seal to avoid air leakage. Then, activate the measurement function, and the device will automatically collect data. Wait for a few seconds until the reading stabilizes, and record the displayed air volume value. If supported by the device, you can save the data to the internal memory. Turn off the device and clean the cap for future use.
4. Application Scenario: This device is suitable for various occasions. In the construction industry, it is used to test the performance of ventilation systems. In industrial environments, it is used to check whether air conditioning and exhaust systems meet standards. In laboratories, it may be used for airflow experiments or environmental monitoring. It is important to note that the device should be used under specified environmental conditions to avoid the impact of extreme temperature or humidity on accuracy.
5. Maintenance and Care: To maintain the performance of the equipment, regular maintenance is required. Clean the cap and sensor, wiping them with a soft cloth and avoiding the use of corrosive cleaning agents. Check the battery status and replace or charge it in a timely manner if the battery is low. Then, calibrate the equipment, following the manufacturer's recommendations for periodic calibration to ensure measurement accuracy. If the equipment malfunctions, contact a professional technician for repair and do not disassemble it yourself.
6. Precautions: When using the DBM620 cap-type air volume meter, the following points should be noted. Avoid using it in flammable and explosive environments to prevent safety accidents. Ensure that the device is operated within the measurement range, as operating it beyond the range may lead to errors or damage. Store it in a dry and dust-free place and avoid mechanical shock. If the device is not used for a long time, it is recommended to remove the battery to prevent leakage.
7. Common Issues Users may encounter some common issues. For example, unstable readings may be due to the cap not being sealed properly and requiring reinstallation. If the device cannot be turned on, check the battery connection or charging status. Display abnormalities may stem from environmental light or settings issues, so adjust the position or restart the device. For more complex issues, refer to the user manual or seek professional support.
8. Cost Considerations: The price of the DBM620 cap-type air volume meter varies depending on the model and features. The basic model may cost around 20,000, while high-end versions with additional features such as data export or advanced sensors may exceed 40,000. When purchasing, it is important to choose based on actual needs, considering long-term usage costs and maintenance expenses.
9. Development Trend: With technological advancements, such devices may evolve towards a more intelligent direction. For instance, integrating wireless connectivity functions to facilitate data transmission. Sensor technology may be enhanced to improve measurement accuracy and response speed. The user interface may become more user-friendly, simplifying the operation process. These improvements are aimed at meeting the industry's demand for efficient and reliable measurements.
10. Conclusion: The DBM620 cap-type air flow meter is a practical measurement tool suitable for various air flow detection scenarios. By operating and maintaining it correctly, long-term reliable operation can be ensured. Users should select the appropriate model based on actual applications and follow the user guide to obtain accurate results.
