Precautions anemometer use: When using the thermal probe in turbulent airflow from all directions at the same time the impact of the heating element, which can affect the accuracy of measurement results. When measured in turbulence, showing the value of the thermal anemometer is often higher than the wheel velocity sensor probe. Above phenomenon can be observed in the course of the measurement pipe. Depending on the design aneroid barometer management pipeline turbulence, even at low speeds will occur. So Precision aneroid barometer, anemometer measurement process should be carried out in the linear portion of the pipe. The starting point of the linear portion should be at least at the measurement point before the 10 × D (D = pipe diameter, unit CM) outside; after the end of at least 4 × D at the measurement point. Fluid-section may not have any shelter (such as edges and corners, heavy floating box barometer manufacturers, etc.). Aneroid barometer is made of an elastic metal thin film sensing element as an empty box, it will empty boxes atmospheric pressure into an elastic displacement, driven pointer through the lever and the transmission mechanism. When clockwise deflected pointer indicates the amount of change in outlet pressure is increased, and vice versa, when the pointer counterclockwise direction, indicating the amount of change in the air pressure decrease. When an empty box of elastic stress and atmospheric pressure equilibrium, the pointer will stop turning, then the pressure indicated by the pointer value is the prevailing atmospheric pressure.
