Application of Communication Technology in Flow Measurement

 Modern communication technology is an emerging technology based on digital technology. It is introduced into the field of measurement and control, which greatly promotes the development of measurement and control technology.The use of digital communication to transmit information is significantly superior to the use of analog signals in the meter.
       ①Accurate
Data transmission by digital communication, supplemented by error detection technology, once successful, there is no error in analog signal transmission.
       ②Saving communication cables
In traditional meters, analog signals are used to transmit information, and a pair of lines can only transmit one signal. In modern communication technology, information is transmitted in a sub-method, and the amount of information that can be transmitted by a pair of lines can reach tens of thousands or even more, thereby greatly saving.
       In the digital display instrument, serial communication is generally used, although the communication rate can only reach 10^3-10^4bps, but the amount of data to be transmitted in the measuring instrument is generally not large, and the communication time interval is also not required. Therefore, it can meet the needs.

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...
