L-type/S standard pitot tube usage method:

　　1.To select the measurement point section correctly, ensure that the measurement point is located in a straight pipe section with smooth airflow. For this purpose, measurement

Local components such as elbows and variable diameter pipes with a cross-sectional distance from the incoming flow direction should be larger than 4 Double the diameter of the pipeline. Leaving the downstream side

Local bends and variable diameter structures should be greater than 2 Double the diameter of the pipeline.

　　2.When measuring, the full pressure hole should be aligned with the direction of the airflow to indicate the direction of the rod. Measurement point insertion holes should be avoided

Leakage can prevent airflow interference on this section. Using a pitot tube can only measure the flow velocity at a certain point on the cross-section of the pipeline,

Due to the uneven distribution of cross-sectional flow, multiple points should be measured on this section to obtain the average value.

　　3.Test the smoothness before use. Regularly check the small static pressure hole to prevent impurities from blocking it after use

Clean the inner and outer pipes regularly to ensure long-term good condition.

　　4.The standard pitot tube calibration cycle is five years.

note:When the choice of pitot tube exceeds1500mmAt this time, our factory suggests that buyers choose to make it in sections, with each section not exceeding a length of1500mm,Because express delivery generally does not accept ultra long items, and the damage rate during transportation is relatively high for ultra long items, our factory ensures airtight and intact connections with leather tubes The head is equipped with silicone gaskets, so you don't have to worry about air leakage. Welcome to visit, the quality meets customer satisfaction, and the price is reasonable.

1Installation point

aIf measuring the wind speed inside the pipeline, the shape of the pipeline must be considered. Generally, the pipeline is circular, and the effective length of the pitot tube should be at least greater than the outer radius of the pipeline. The installation point can be arbitrary; If it is a square pipeline, a small distance from the center point can be chosen as the installation point, which can save the material of the pitot tube

bIf measuring the air outlet, the pitot tube can be of any length without the need for fixed installation, just hold it in your hand for measurement

2When measuring at any location, the measurement point must be selected as the wind speed center point
