Application and characteristics of air flow meter

Abstract: The application and characteristic information of air flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. There are many kinds of flowmeters that can measure compressed air, and each kind of flowmeter will have its own advantages and disadvantages in actual use, so when we choose a flowmeter, we should choose the most suitable flowmeter according to the actual parameters. automated industry. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the application and characteristics of air flowmeters. There are many kinds of flowmeters that can measure compressed air, and each kind of flowmeter will have its own advantages and disadvantages in actual use, so when we choose a flowmeter, we should choose the most suitable flowmeter according to the actual parameters. In the industrial automation process, there are many kinds of instruments used to measure air flow, but there are not many classifications according to their principles. In practical applications, there are usually several reasons for the error of the flow meter: 1. Most of the fluids at the outlet of the compressor and blower contain a certain pulsation. Fluid pulsation will cause the differential pressure flowmeter, vortex flowmeter and other flowmeters to show high values, causing the rotor in the metal rotor flowmeter to jump up and down. In order to eliminate the influence of pulsation, a buffer tank is generally installed at the outlet of the compressor to filter out the pulsation, and the flowmeter is installed behind the buffer tank; or the flowmeter is installed away from the pulsation source. 2. Compressed air is taken from the atmosphere, and the atmosphere always contains a certain amount of water vapor. For larger-diameter orifice flowmeters used to measure the flow of compressed air, water often accumulates in front of the orifice, which will affect the measurement accuracy. There is often a section of water in the impulse pipe, which causes the differential pressure measured by the differential pressure transmitter to be inconsistent with the differential pressure generated by the throttling device. These are common causes of errors caused by water in the air. 3. The flowmeter for measuring compressed air is generally installed in the compressor room and the blower room, and the vibration generated by the compressor and the blower will be transmitted to a long distance through the air duct or air duct. Vibration causes the vortex flow sensor to generate an interference signal corresponding to the vibration frequency, causing the flow indication value to be significantly higher. 4. Annubar flowmeter has its own unique advantages for large-diameter air flow measurement. It is cheap, simple and reliable, and easy to install and maintain. It is a supplement to vortex flowmeter and throttle differential pressure flowmeter. The above is the whole content of this article.
