The characteristics of gas flow measurement

       The measurement of gas flow mainly refers to the measurement of the flow rate of city gas, natural gas, air duct, boiler and various furnace flue gas, flare gas in petroleum refinery and petrochemical industry. The measurement of these flows is important for economic combustion, environmental protection, and trade settlement.
      The characteristics of gas flow measurement：
      a.Large calibers, straight sections are often difficult to guarantee.
      b.Low static pressure, low flow rate, only a small pressure loss is allowed.
      c.The flow rate range varies greatly, requiring a large range of gauges.
      d.The fluid contains dust and sometimes contains sticky notes of tears.
      e.Some fluids are somewhat corrosive.
      f.The composition of the gas varies.
      g.The fluid temperature is high.
      h.Some flue gas temperatures decrease, and when the temperature rises, even with liquid.

Electromagnetic flow meter and vortex flow meter What are the differences

图片
        As a professional supplier of flow meter, it is very important to use the flow meter users, talk about two kinds of widely used two flow meters. The first is the electromagnetic flow meter, the second is the vortex flow meter. This is what we often use most of the two flow meters. What is the difference between them before? I will tell you from the following points: 1. Electromagnetic flow meter and vortex flow meter principle is different.    According to the principle of flange electromagnetic induction, a pair of test electrodes are installed on the wall of the tube which is perpendicular to the axis of the measuring tube and the magnetic field lines. When the conductive liquid moves along the axis of the measuring tube, the conductive liquid cuts the magnetic field lines to generate the induced potential. The sensing potential is detected by two sensing electrodes. The value is proportional to the flow rate. The value is E = B * V * D * ...

Precautions for the installation of electromagnetic flowmeter

图片
     The electromagnetic flowmeter is an instrument for measuring the volume flow of the conductive fluid through the electromotive force induced by the applied magnetic field according to "Faraday electromagnetic induction principle". It consists of two parts, the sensor and the converter. It is suitable for measuring the flow of conductive liquid and slurry in closed pipes, such as clean water, sewage, various acid and alkali salt solutions, mud, pulp, pulp and food liquids.With the development of industrial technology, the advancement of agricultural science and technology.Due to its own advantages and characteristics, the use of electromagnetic flowmeter has been increasing every year.  At the same time as the amount of use is increased, the following items must be noted in the installation of the electromagnetic flowmeter:      The electromagnetic flowmeter should be installed in the correct position.     1. Installation method (as...
