Flow measurement characteristics in the power industry

  When it comes to the power industry, it is associated with large boilers and high-temperature and high-pressure steam in thermal power plants. It is thought that the large-diameter pipe network of thermal power plants supplies steam to various users. Therefore, the measurement of steam flow in the thermal power and thermoelectric industries is large.According to its use and characteristics, it can be roughly divided into flow measurement related to power generation and flow measurement in heating network.
    （1）Steam measurement related to power generation
This type of flow measurement is characterized by high fluid temperatures and high pressures. Even for small units of several megawatts, its steam temperature is as high as 420 °C.Although new flow meters are often introduced, most flow meters cannot withstand such harsh operating conditions.Currently, the throttling differential pressure flow meter is suitable for this environment.
   （2）Steam flow measurement in heating network
The flow meter used in the heating network of the thermal power plant, because the temperature and pressure of the fluid are greatly reduced, the space that can be selected is greatly expanded. However, due to the tradition of instrument selection in the power plant, most objects still use the throttling differential pressure flow meter.Part of the selection of vortex flow meter.

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...
