What is an electromagnetic flowmeter?
Electromagnetic flow meters are divided into two display modes: split type electromagnetic flow meters and integrated type electromagnetic flow meters.. Series nominal diameter DN15~DN3000. The split type electromagnetic flowmeter is an induction instrument that measures the volume flow rate of conductive medium inside a tube based on Faradays law of electromagnetic induction. It uses embedded microcontroller technology to achieve digital excitation, and adopts CAN fieldbus on the electromagnetic flowmeter, which is the first of its kind in China and has reached the leading level of technology in the country. The split type electromagnetic flowmeter can not only meet on-site display requirements, but also output 4-20mA current signals for key recording, adjustment, and control. It has been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage. In addition to measuring the flow rate of general conductive liquids, the split type electromagnetic flowmeter can also measure the volumetric flow rate of bridging liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids. The integrated electromagnetic flowmeter is developed based on Faradays law of electromagnetic induction and is used to measure the volumetric flow rate of conductive fluids. Due to its unique characteristics, it has been widely used in the measurement of various conductive liquids in industry. Mainly used in industries such as chemical, papermaking, food, textile, metallurgy, environmental protection, and water supply and drainage, it can achi
2. Introduction to Split type Electromagnetic Flowmeters
Electromagnetic flowmeters are classified according to the assembly method of converters and sensors, including split type and integrated type.
. Split type electromagnetic flowmeter is the most commonly used form of electromagnetic flowmeter, as shown in the figure below. The sensor is connected to the pipeline, and the converter is installed near the sensor in the instrument room or easily accessible to people, with a distance of several tens to hundreds of meters. To prevent external noise from entering, signal cables usually use dual core shielded wires. When measuring liquids with low conductivity and aiming to gather more than 30m apart, in order to prevent signal attenuation caused by the capacitance of the cable, it is also required to connect a shielding driver with the same potential and low impedance source as the core wire to the inner shielding. The converter of the split type electric side chain magnetic flowmeter can be kept away from harsh on-site environments, making electronic component inspection, adjustment, and parameter setting more convenient.3. What are the classifications of electromagnetic flow meters?
According to the measurement principle and structural characteristics of electromagnetic flow meters, they can be classified into different categories, including: Xiangdan 1 Electromagnetic induction electromagnetic flowmeter and liquid capacitive electromagnetic flowmeter: These are two common measurement principles of electromagnetic flowmeters. The working principle of an electromagnetic induction flowmeter is based on Faradays law of electromagnetic inductio
