Introduction to the performance analysis of electromagnetic flowmeter

The English name of the flow meter is flowmeter, which is defined by the National Scientific and Technical Terminology Committee as a meter indicating the measured flow rate and/or the total amount of fluid in the selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.

The flowmeter is further divided into a differential pressure flowmeter, a rotameter, a throttle flowmeter, a slit flowmeter, a volumetric flowmeter, an electromagnetic flowmeter, an ultrasonic flowmeter, and the like. Classified by media: liquid flow meter and gas flow meter.

Metrology is the eye of industrial production. Flow measurement is one of the components of metrology science and technology. It has a close relationship with the national economy, national defense construction, and scientific research. Doing this work will play an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology, especially in the current era of energy crisis and industrial automation. Flowmeters are in the national economy. The status and role of the more obvious.

The unit m3/h is commonly used in engineering. It can be divided into flow rate and total flow. The instantaneous flow rate is the amount of the effective cross section of the closed pipe or open channel per unit time. The material flowing through can be gas. Liquid, solid; cumulative flow is the cumulative amount of fluid flowing through a closed pipe or open channel at a certain time interval (one day, one week, one month, one year). The instantaneous flow rate can also be used to calculate the cumulative flow rate by integrating the instantaneous flow rate, so that the instantaneous flow meter and the cumulative flow meter can also be converted into each other.

In order to ensure the normal operation of industrial production, accurate monitoring is always necessary during the production process. Electromagnetic flowmeter is an important unit in production monitoring and is widely used in many industries such as chemical industry, metallurgy and medical treatment. The electromagnetic flowmeter is composed of two parts: the sensor directly contacting the pipeline medium and the upper signal converter. Through the induction and conversion of the signal, we can accurately understand the current production status.

On the basis of the traditional flowmeter, the electromagnetic flowmeter adds a magnetic field to both sides of the pipeline. The measured medium flows through the pipeline to cut the magnetic lines of force, and an induced potential is generated on the two detecting electrodes, the magnitude of which is proportional to the moving speed of the fluid. The electromagnetic flowmeter has good sealing performance and can also be used in tap water and underground waterway systems, and is widely used for liquid or semi-liquid material measurement.

The electromagnetic flowmeter is a high-precision, high-reliability and long-life flow meter, so it is necessary to pay great attention to detail in designing product structure, material selection, manufacturing process, and factory inspection. Most electromagnetic flowmeters now have a liquid crystal display, which is fully functional and practical, intuitive to display, easy to operate and use, and can reduce the inconvenience caused by other electromagnetic flowmeter English menus.
