1. Sebelum gunakan, amati apakah the pointer of the meter points to zero. If there is any deviation, gently adjust the mechanical adjustment screw of the meter to return the pointer to zero;
2. Tempat the kalibrasi switch in the off posisi
3. Insert the plug of the measuring rod into the socket, place the measuring rod vertically upwards, press the plug tightly to seal the probe, place the "calibration switch" in the full degree position, and slowly adjust the "full degree adjustment" knob to make the meter pointer point at the full degree position;
4. Place the "calibration switch" in the "zero position" and slowly adjust the "coarse adjustment" and "fine adjustment" knobs to make the meter pointer point at the zero position
5. After the above steps, gently pull the plug to expose the probe of the measuring rod (length can be selected according to needs), and make the red dot on the probe face the wind direction. Based on the reading of the electricity meter, refer to the calibration curve to find the measured wind speed;
Setelah mengukur beberapa poin (sekitar 10 menit), the above steps 3 and 4 must be repeated once to standardize the current inside the instrument
7. Setelah pengukuran adalah selesai, the "kalibrasi switch" should be placed in the off position.
An anemometer is a kecepatan pengukuran instrumen itu mengubah aliran kecepatan sinyal ke-listrik sinyal, dan bisa juga mengukur cairan suhu atau kepadatan. Prinsip adalah ke-tempat a tipis logam kawat dipanaskan oleh listrik dalam aliran, dan panas disipasi dalam dalam aliran aliranudara adalah terkait ke aliran laju. The panas disipasi penyebab suhu perubahan dan resistansi perubahan, dan aliran tingkat sinyal is dikonversi menjadi listrik sinyal.
Anemometer Penggunaan
1. Ukur kecepatan dan arah dari rata-rata aliran.
2. Measure the pulsation velocity and its spectrum of the incoming flow.
3. Ukur the Reynolds stres dalam turbulensi dan kecepatan dan waktu korelasi antara dua titik.
4. Ukur the dinding geser tegangan (biasanya menggunakan a panas film probe ditempatkan menyiram dengan dinding, mirip dengan prinsip dari kecepatan pengukuran).
5. Measure the fluid temperature (by measuring the variation curve of the probe resistance with the fluid temperature in advance, and then determining the temperature based on the measured probe resistance).
