Abstract: the right way to use the pitot tube information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. To correctly choose measurement point section, to ensure the measuring point straight pipe in air flow smoothly. Therefore, measuring the cross section from the flow direction of the elbow, valve, variable diameter abnormity tube local component is greater than 4 times the pipe diameter. From the downstream direction. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the right way to use the pitot article details. To correctly choose measurement point section, to ensure the measuring point straight pipe in air flow smoothly. Therefore, measuring the cross section from the flow direction of the elbow, valve, variable diameter abnormity tube local component is greater than 4 times the pipe diameter. From the downstream direction of local bend, the structure of the variable diameter should be greater than 2 times the pipe diameter. The diameter of the pitot tube specification selection principle is measured pipeline diameter ratio, and is not greater than zero. 02. In order to avoid interference, make error increases. Don't let the pitot tube measurement near the pipe wall. When measuring the total pressure hole shall be on the airflow direction, to point to the pole. Measurement point should try to avoid air leakage on insert hole, to prevent the air section. According to the pipeline measurement technology specification, should choose reasonable measuring point of the measurement section. Pitot tube can only be measured on the pipeline section velocity of one point, but the average flow velocity should be used when calculating flow, because of the uneven distribution of cross section flow, so this section should be more measuring points, in order to calculate the average. Measuring point by flue ( Pipe) Law, measurement & other; A linear logarithmic & throughout; Method divided, can also according to the commonly used uniform area. The S type pitot static pressure tapping on marked number, and note the pitot tube on the identification of single factor. Identification of single should be kept for a long time for computation. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
