QDF-6 digital anemometer with thermal sensitive probe:
The working principle of the thermal sensitive probe of the QDF-6 hot ball anemometer is based on the cold shock airflow carrying away the heat from the heating element. With the help of an adjustment switch, the temperature is kept constant, and the current and flow rate are proportional to each other. When using a thermal sensitive probe in turbulence, airflow from all directions simultaneously impacts the thermal element, which can affect the accuracy of the measurement results. When measuring in turbulence, the reading of the thermal anemometer flow sensor is often higher than that of the rotary probe. The above phenomenon can be observed during pipeline measurement. According to different designs for managing turbulent flow in pipelines, it may even occur at low speeds. Therefore, the anemometer measurement process should be carried out in the straight section of the pipeline. The starting point of the straight section should be at least outside the measurement point * × D (D=pipe diameter, in CM); The endpoint should be at least 4 × D behind the measurement point. The fluid cross-section must not have any obstruction.
