1. Detailed introduction to the working principle of electromagnetic flowmeter.
Introduction to the working principle of electromagnetic flowmeter. Electromagnetic random disassembly flowmeter is an instrument based on electromagnetic induction principle to measure the flow rate of conductive medium. It determines the flow rate by measuring the induced electromotive force generated by a conductor in a magnetic field. Specifically, there is a specific magnetic field inside the flowmeter, and when a conductive medium flows through this magnetic field, an induced current signal is generated, which is proportional to the flow rate of the medium. Finally, the induced current signal is converted into flow data for users to read and use. Detailed explanation
1. Basic composition of electromagnetic flowmeter. Electromagnetic flowmeter mainly consists of three parts: sensor, converter, and display instrument. The sensor includes a measuring tube and an excitation system, responsible for generating a magnetic field and detecting induced signals; The converter is responsible for amplifying and processing the sensing signal; The display instrument is used to display flow data. When the conductive medium flows through the measuring tube of the sensor, it will cut the magnetic lines in the magnetic field, thereby generating induced electromotive force in the conductive medium. The magnitude of the electromotive force of this ribbon jujube is directly proportional to the flow velocity and magnetic field strength of the medium. After amplification and processing by a converter, the induced electromotive force is converted into a standard signal that is linearly related to the flow rate, and then output in digital or ana
4. The characteristics of electromagnetic flowmeter include high measurement accuracy, fast response speed, and the ability to measure media with conductivity ≥ 5 μ s/cm.
. In addition, it can also achieve remote monitoring and automation control, and is widely used in industrial fields such as chemical engineering, water treatment, food and beverage, and pharmaceuticals. Due to its working principle based on electromagnetic induction, it is not affected by fluid temperature, pressure, and viscosity, and has good stability. The above is a detailed introduction to the working principle of electromagnetic flowmeter. This flowmeter is based on the principle of electromagnetic induction, which determines the flow rate by measuring the induced electromotive force generated by a conductive medium in a magnetic field. It has multiple advantages and a wide range of application fields.2. How to adjust the electromagnetic flowmeter?
The adjustment method of electromagnetic flowmeter is as follows
1. Firstly, you need to enter the password to enter the menu and find the caliber setting column.
. For example, if the caliber is set to DN50, to increase the flow rate, the caliber can be modified to DN65, which will naturally increase the flow rate. Secondly, the flow rate can also be changed by adjusting the K coefficient. Enter the password to enter the menu and find the K coefficient column. For example, if the K coefficient is 1.065, increasing the K coefficient value will correspondingly increase the flow rate. Attention: Non staff members should not adjust the flow parameters arbitrarily t
