Flute type flange type pitot tube Abaniu equal speed tube static pressure tube

The flute shaped pitot tube (averaging tube) is called the Annubar averaging tube.Flute type flange type pitot tube Abaniu equal speed tube static pressure tubeIt is developed based on the principle of measuring flow velocity using pitot tubes. Due to its low pressure loss, low manufacturing cost, and easy installation and maintenance, it is widely used for measuring the uniform velocity or flow rate of gases or liquids in various pipelines (square or circular pipes). Using a pitot tube to measure flow velocity is a mature and reliable measurement method.

Flute type flange type pitot tube Abaniu equal speed tube static pressure tubePrinciple and Application:
It is a hollow metal tube with flanges and multiple sets of total pressure holes drilled on the upstream side, which are located at the * of each unit area and reflect the flow velocity within each unit area. As each total pressure hole is connected, the average total pressure value at each point is transmitted to the high-pressure tapping port through the total pressure outlet pipe.

Usage:

1. It is necessary to select the measurement point section correctly and ensure that the measurement point is located in a straight pipe with smooth airflow

Section. For this purpose, measure local components such as elbows and variable diameter pipes that are away from the incoming flow direction

It should be greater than 4 times the diameter of the pipeline. Local bends and variable diameter structures in the downstream direction should be greater than

2 times the diameter of the pipeline.

When measuring, the full pressure hole should be aligned with the direction of the airflow to indicate the direction of the rod. measurement

The insertion hole should avoid air leakage to prevent airflow interference on the section. Using a leather tube can only

The flow velocity at a certain point on the cross-section of the pipeline was measured. Due to the uneven distribution of flow rate on the cross-section

More 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

Clean the inner and outer pipes promptly after using the small hole to ensure good condition.

The standard pitot tube calibration cycle is five years.
