Installation Precautions for Air Flow Meters

Abstract: The information on the installation precautions of air flow meter is provided by the excellent flow meter and flow meter manufacturer and quotation manufacturer. From the working principle, structure, characteristics and design selection of the air flow meter, the installation of the air flow meter should pay attention to the following 10 points: 1. Select the installation location and position of the air flow meter according to the needs, but the electrode axis must be roughly in the horizontal direction ; 2. Note. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the installation precautions for air flow meters. From the working principle, structure, characteristics and design selection of the air flow meter, the installation of the air flow meter should pay attention to the following 10 points: 1. Select the installation location and position of the air flow meter according to the needs, but the electrode axis must be roughly in the horizontal direction 2. Note that the flow direction on the air flow meter is consistent with the actual flow direction of the fluid; 3. The measuring tube must be completely filled with the medium at all times. Only when the tube is full can an accurate measurement be obtained. For the installation method of the anti-rejection valve, do not install it at the lowest point to prevent solid accumulation. In addition, in order to prevent the generation of vacuum, avoid installing the sensor on the inlet end of the pump; 4. When installing, ensure that the sensor is close to the pipeline. There is enough space at the flange; 5. The pipes on both sides of the air flow meter should be firmly supported, and should not be installed in places with strong vibration; Axial displacement of the butt flange; 7. Measured from the electrode axis, the length of the shortest straight pipe section upstream is 5DN, and the length of the shortest straight pipe section downstream is 2DN (DN is the inner diameter of the pipe); 8. For the air flow meter, the signal converter should be connected (and the power booster); install it as close to the sensor as possible, the connecting wire should be a shielded cable, preferably a double-layer shielded cable, and do not expose the signal converter (or power booster) directly to the sun, if any If necessary, a sun shield can be installed; 9. For the vortex or spiral flow of the fluid, lengthen the upper and lower straight pipe sections and install a flow straightener; 10. In order to make the instrument work reliably and improve the measurement accuracy, it is not affected by the outside world. The interference of parasitic potential, the sensor should have a good separate grounding wire, and the grounding resistance is less than 10Ω. The above is the whole content of this article.
