Electromagnetic flowmeter, open flow meter, trustworthy introduction

The electromagnetic flow meter is manufactured according to Faraday's law of electromagnetic induction, and its function is to measure the volumetric flow of the conductive medium in the tube. It has the advantage that the pressure loss is extremely small and the flow range is large, so its use in the measuring instrument industry is relatively frequent. In addition to electromagnetic flowmeters, there are orifice flowmeters that are frequently used in the measuring instrument industry. These two measuring instruments can be said to be the oldest and second in the measurement industry. Almost every instrument company has such an instrument, just as Open Flow Instrument Technology Co., Ltd. is very trustworthy in the instrument industry. The electromagnetic flowmeter produced by their company is the most high-quality flowmeter of the company for many years, and has won the favor and praise of many customers. If the measurement industry can adapt to the development of society and the requirements of customers, then this will be a very significant business opportunity.

There are many types of electromagnetic flowmeters for open flow meters, and they are classified according to different types. For example, according to the flow sensor and pipe connection methods, there are flange clamp connections, flange connections, threaded connections and sanitary connections. If differentiated by excitation current, there are DC excitation, double-frequency rectangular wave excitation, AC (power frequency or other frequency) excitation and low frequency rectangular wave excitation. If classified according to the flow sensor structure, there are short tube type and insert type. If classified by purpose, there are general-purpose, hygienic, explosion-proof, water-proof, submersible, etc. In the selection, you should pay attention to the target you measured, and choose different electromagnetic flowmeters according to the target, so that you can save more resources.

What should be paid attention to in the electromagnetic flowmeter? What is the difference in its installation requirements? First, it should be noted that the liquid to be measured should have the conductivity required for the measurement, and the distribution of the conductivity should be generally evenly distributed. Then, the flow sensor should be installed away from the place where the conductivity is not uniform. When the sensor is used, the measuring tube must be filled with liquid (unless the full tube type is used). If there is mixing, the distribution of the liquid should be substantially uniform. At the same time, the liquid should be at the same potential as the ground and must be grounded. For example, when the process pipe is made of an insulating material such as plastic, frictional static electricity or the like is generated when the liquid is transported, which causes a potential difference between the liquid and the ground, and the measured data differs. Second, in the installation process should pay attention to: 1, when measuring the mixed phase fluid, should choose the place that will not cause phase separation; when measuring the two-component liquid, should not be installed in the downstream of the mixing is not uniform; when measuring the chemical reaction pipeline It should be installed downstream of the fully completed reaction section. 2. Avoid the environment of high concentration of corrosive gases. 3. It should be installed in a place where it is protected from direct sunlight. 4. It can't be installed in places where rainwater is immersed. 5, should try to avoid nearby large motors, large transformers and other equipment, so as not to cause electromagnetic interference, and thus affect the measurement data. 6. Try to avoid the negative pressure inside the measuring tube as much as possible. 7. Installed in a place where the sensor can be grounded separately. The above is the installation requirements of the electromagnetic flowmeter by Kailiu Instrument Technology Co., Ltd. I believe this is also the requirement of most instrument manufacturers, so we should pay attention to the above points in the future installation process. Kailiu Instrument Technology Co., Ltd. is one of the best companies in the world in terms of products and technology. It has been well received by many customers and their after-sales service is quite good.
