How does a hot bulb anemometer work?
A hot ball anemometer is a portable, intelligent, and multifunctional basic instrument for measuring low wind speed, which uses the principle of calorimetry to measure wind speed;
It has a wide range of applications in heating, ventilation, air conditioning, environmental protection, energy conservation monitoring, meteorology, agriculture, refrigeration, drying, labor hygiene investigation, and other fields.
Working process:
Place the measuring rod vertically upwards in the tested environment. This is done to reduce the zero compensation error caused by the difference between the temperature of the measurement point and the ambient temperature. The plug is tightened to seal the probe.
Press the power button once to turn on the device. At this point, the meter enters the preheating state and automatically compensates for the zero position of the wind speed, which takes about half a minute.
After the zero compensation of preheating and wind speed is completed, this table will check whether the printer is connected;
When measuring wind speed, the measuring rod should be pulled out to allow the measured wind to pass through the window where the sensitive element is located, and the red dot should face the incoming wind.
When measuring wind speed in a fast and immediate manner, the display window will track and display changes in the measured wind speed in a timely manner;
And detect the voltage of the battery. If the voltage of the battery is insufficient, the prompt LOW will be displayed to remind the user to replace the battery or use an external power source in a timely manner.
Note that in wind speed measurement, the thermistor on the probe must be aligned with the incoming wind direction.
