Application of Temperature Flow Meters

 A temperature flow meter is a precision instrument used to measure gas flow and temperature, widely applied in environmental monitoring, air conditioning systems, industrial manufacturing, and related fields. Its fundamental principle involves detecting temperature variations caused by gas flow to accurately calculate airflow velocity and volume, thereby providing users with precise data support. The instrument's key features lie in high precision and rapid response. Typically equipped with advanced sensors, it can swiftly capture minute changes in flow rate and provide real-time feedback. Its measurement accuracy remains exceptional even under complex environmental conditions, which is particularly crucial for industrial applications requiring strict control of airflow and temperature. Additionally, the operation of temperature flow meters is relatively simple—users only need basic configuration to obtain required data. This user-friendly design makes it easy for both professionals and general users to operate. Many modern models also feature digital displays with intuitive interfaces, allowing users to quickly understand current status and enhance usability. The instrument demonstrates excellent stability, maintaining consistent measurements over extended periods without significant drift, ensuring data reliability. With continuous technological advancements, many devices now integrate data storage and transmission functions, enabling users to review and analyze historical data post-test for informed decision-making. In conclusion, the thermal anemometer has become an indispensable tool in various industries due to its high precision, rapid response, user-friendly operation, and excellent stability. In daily life and professional settings, mastering this instrument not only enhances work efficiency but also provides crucial support for scientific research and engineering applications. As a vital measurement technology in modern science, it plays a pivotal role in technological advancement.

What are the customization processes of non-standard test boxes?

1. Communicate with manufacturers directly to customize requirements

 operating steps :

Requirement submission: clear the test object (such as headlights, batteries, sensors, etc.), test scenario (such as simulated extreme cold wading, high temperature and high pressure spraying) and industry specifications (such as automobile, military, electronics);

Technology docking: provide product parameters (size, weight), environmental conditions (temperature range, impact frequency) and special requirements (such as salt spray superposition test, dynamic Angle adjustment);

Confirmation of the scheme: Based on general standards such as GB, IEC and GJB, and industry specifications such as VW 80101 and ISO 16750, the manufacturer designs customized test procedures and equipment configuration schemes.

2. Adapt to the existing standard framework

Manufacturers can expand or adjust based on the following criteria:

 national standards :

GB/T 28046.4-2011: For the climate load test of automotive electrical equipment, the core parameters such as temperature, time and circulation times of ice water impact are defined;

GB/T 2423.1: Environmental test specification for general electrical and electronic products, supporting the design of calibration and verification process.

 codes of practice :

VW 80101-2005: Volkswagen Electric Components Test Standard, applicable to the refinement of parameters such as spray pressure and water temperature accuracy;

GMW3172: General Motors global engineering standard, supporting multi-environment composite testing (such as ice water impact + salt spray corrosion);

ISO 16750-4:2006: International common vehicle electrical equipment test framework, compatible with customized cycles (e.g. 100 standard or 200 enhanced).

Third, optimize standards by using manufacturers' technical resources

Flexible parameter adjustment:

Temperature range: standard high temperature range 65~160℃, can be extended to-70℃ to +150℃;

Water splashing system: support flow (3~4L/3S or 80L/min), distance (325±25mm adjustable), nozzle type (gap/matrix) and other customization;

Intelligent control: the PLC system can customize the temperature switching rate (such as 20 seconds to complete the conversion from extreme cold to high temperature), data acquisition frequency and report format.

Function module superposition:

Compatible with multiple test requirements such as waterproof (IPX5-6) and dustproof (IP5X-6X);

Support dynamic Angle spraying (15 ~75 adjustable), salt spray composite test and other complex scene simulation.

4. Ensure compliance through certification and verification

Equipment calibration: the manufacturer provides half-year temperature sensor calibration service, the error is controlled within ±2℃;

Third-party verification: it is recommended to certify the temperature change rate, uniformity and other indicators of customized equipment through quality inspection institutions (such as China Electric Power Research Institute, FAW test site);

Data traceability: The test chamber supports USB export of test logs, which is convenient for quality traceability and standard iteration.

5. Service support and case reference

Technical team: Guangdong Hongzhan cooperates with universities and research institutes to provide whole-process support from demand analysis to standard implementation;

Case library invocation: You can refer to the car company case (such as 800V battery pack IPX9K test, intelligent lamp cold and hot cycle verification) to optimize and customize the standard;

After-sales guarantee: customized equipment enjoys 1 year warranty and 48 hours door-to-door maintenance to ensure the stability of standard implementation.

key points of choosing high and low temperature test chamber

Eight key points of choosing high and low temperature test chamber:

1.No matter whether it is selected for high and low temperature test chamber or other test equipment, it should meet the temperature conditions specified in the test requirements;

2.To ensure the uniformity of temperature in the test chamber, forced air circulation or non-forced air circulation mode can be selected according to the heat dissipation of samples;

3.The heating or cooling system of the high and low temperature test chamber shall have no effect on the samples;

4.The test chamber should be convenient for the relevant sample rack to place samples, and the sample rack will not change its mechanical properties due to high and low temperature changes;

5. High and low temperature test chamber should have protective measures. For example: there are observation window and lighting, power disconnection, over-temperature protection, various alarm devices;

6. Whether there is remote monitoring function according to customer requirements;

7. The test chamber must be equipped with automatic counter, indicator light and recording equipment, automatic shutdown and other instrument devices when carrying out the cyclic test, and it must have good recording and display functions;

8.According to the sample temperature, there are two measurement methods: upper wind and lower wind sensor temperature. The position and control mode of temperature and humidity control sensor in the high and low temperature test chamber can be selected according to the customer's product test requirements to select the appropriate equipment.
