Electromagnetic flowmeter has been widely used in the world, which is related to sewage, chemical, pharmaceutical, paper, food and other industries. Large caliber instruments are often used in water supply and drainage engineering. Small and medium caliber used in solid-liquid double fluid or high places are equal. Small caliber, small caliber commonly used in the pharmaceutical industry, food industry, biological engineering and other places of health requirements. Changzhou Cheng Feng is a flow meter to produce the old factory, all kinds of flow meter variety, service quality is excellent.
The working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, when the conductive metal rod with a certain speed, do the movement vertical to the direction of the magnetic field lines, which will generate induced voltage. In the electromagnetic flow meter, the electric conduction medium in the tube is equivalent to the conducting metal rod in the Faraday test, and a constant magnetic field is generated at the upper and lower ends of the upper and lower ends of the two electromagnetic coils. When a conductive medium flows through, it generates an induced voltage. The sensing voltage generated by the two electrode measurements inside the pipe. Measuring the electromagnetic isolation of the fluid and measuring electrode by means of a non conducting liner (rubber, PTFE, etc.).
Classification by converter and sensor assembly, there are two types of separation and one type. In the process of sewage treatment, the large diameter flowmeter is divided into a type, and a part is installed on the ground and the other is on the ground. Small caliber to one type of multi. And the diameter of the electromagnetic flowmeter is wider than the other varieties. The premise of using an electromagnetic flowmeter is that the liquid must be electrically conductive.
Electromagnetic flow meter is not influenced by temperature, pressure, viscosity and other factors, and the pressure loss caused by the internal non shrinkage or protruding part of the tube, and the initial signal of the flow element is a voltage, which is not related to the other properties of the fluid. According to the characteristics of sewage flow, such as large flow, containing impurities, small corrosion, and certain electrical conductivity, it is a good choice to measure the flow of sewage. It has compact structure and small size. Installation, operation, maintenance convenient, measurement system using intelligent design, the overall sealing to strengthen, can work in a more severe environment. So in the water and sewage industry, electromagnetic flowmeter, especially large diameter electromagnetic flowmeter has great advantages, has been widely used.
Enterprises to survive to develop, it is necessary to ensure the quality of the premise, to ensure the quality of services for the customer satisfaction, which also need to have a certain profit to continue. Changzhou Cheng Feng put the price set at a reasonable position, only the normal survival and development of the enterprise, our users can get better products and continuous service, which is a win-win situation.
