Electromagnetic Flowmeters (EMF for short) is a new type of flow measuring instrument that developed rapidly with the development of electronic technology in the 1950s and 1960s. It is an instrument that measures the flow of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. However, the original electromagnetic
flowmeter has a single measuring medium and is subject to greater external interference, so it is less used. However, with the development of science and technology, the technology is more advanced. The current electromagnetic flowmeter tends to be more intelligent and measure the medium. It is more extensive and is less affected by external interference, so it is gradually used by everyone. So first of all, I will introduce the structure of the intelligent electromagnetic flowmeter and the applicable occasions. Structure: The structure of the intelligent electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring catheter, electrode, shell, lining and converter. Applicable media and occasions: From the structure of the intelligent electromagnetic flowmeter I introduced for you above, you can know that the intelligent electromagnetic flowmeter has a structure called lining, which is also the most direct structure that contacts the medium, but not all media are suitable For one type of lining, different linings should be used for different media. The lining material should be selected according to the corrosiveness, abrasiveness and temperature of the measured medium: 1, natural rubber (soft rubber) 1, better elasticity, abrasion resistance and tearing force 2, resistance to general weak acids and weak alkalis 3, water, sewage, acid-resistant rubber (hard rubber) can withstand the corrosion of hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide at room temperature, but not strong The corrosion test of oxidant is common acid, alkali, salt solution 3. Neoprene (Neoprene) 1. Excellent elasticity, high breaking force, good wear resistance 2. Resistance to general low concentration acid, alkali, salt solution Corrosion, but not resistant to the corrosion of oxidizing media <80℃; test water, sewage, mud and ore pulp Four, polyurethane rubber (Polyurethane) 1, excellent wear resistance 2, acid and alkali resistance is poor <40℃ test Neutral and strong abrasive coal slurry, mud and mineral slurry 5. Polytetrafluoroethylene (PTFE) 1. Boiling resistant hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali and various organic solvents 2. Good abrasion resistance, bonding Poor performance -80~+180℃; measures the concentration, strong alkali, strong corrosive solution and sanitary medium. From the structure of the intelligent electromagnetic flowmeter and the applicable media I introduced for you above, I must have already had some ideas about the intelligent electromagnetic flowmeter. A preliminary understanding, but there are still many customers who will say that there are so many intelligent electromagnetic flowmeter manufacturers on the market, and the quality is uneven, how should I choose? Then what I want to tell you is that I am choosing intelligent electromagnetic flowmeter manufacturers. At this time, quality is of course the primary consideration, but it is not very absolute. At present, there is nothing in China or even in the world that will never be broken after purchase. Smart electromagnetic flowmeters are no exception. Then after-sales service is particularly important, especially It is an industrial product such as a smart electromagnetic flowmeter. Once it is damaged, it cannot be repaired in time, and the delay of the project will bring great economic losses to the customer. So when everyone is entangled in choosing which intelligent electromagnetic flowmeter manufacturer to choose, I recommend Kaidi Sensing Technology Co., Ltd., Kaidi’s electromagnetic flowmeter adopts advanced technology, has strong anti-corrosion ability, strong anti-interference ability, and can not measure Affected by changes in fluid density, viscosity, temperature, pressure and conductivity, and there are nearly 20 offices in China, which can arrive at your site as soon as you need technical support to solve your problems. Therefore, everyone When considering smart electromagnetic flowmeter manufacturers, consider Kaidi Sensing Technology Co., Ltd.
Nowadays, it is very common for us to utilise in customized level indicator. And the quality of is decisive to production efficiency.
Guangdong Kaidi Energy Technology Co., Ltd. plans to produce and execute four marketing seminars, one per quarter, to help business owners see success by sharing important growth strategies and hosting interactive workshops.
give you an additional customized level indicator option for your customized level indicator, whether it being a customized level indicator, customized level indicator or customized level indicator. Go and get more info at Kaidi level indicator.
