1. Classification of Electromagnetic Flowmeters

How to classify electromagnetic flowmeters and what are the types? This article provides a detailed introduction to the classification of electromagnetic flow meters; If you think the answer is helpful to you, please kindly give a thumbs up to the US Weidun VTON flowmeter! There are many classification methods for electromagnetic flow meters, and each classification has many subcategories corresponding to it. When selecting, we need to have a basic understanding of this, which can guide our selection. This article provides a detailed analysis of how to classify electromagnetic flow meters.

1. Classification by assembly method of sensors and converters

1. Split type electromagnetic flowmeter: Split type is the most commonly used form of electromagnetic flowmeter, with sensors connected to pipelines and converters installed in instrument rooms or near sensors that are easily accessible to people, with distances ranging from tens to hundreds of meters.

. To prevent external noise from entering, signal cables usually use double-layer shielding. When measuring liquids with low conductivity and gathering for more than 30m, in order to prevent signal attenuation caused by partial 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 separated converter can be kept away from harsh on-site environments, making electronic component inspection, adjustment, and parameter setting more convenient.

2、 Integrated electromagnetic flowmeter: The sensor and converter are assembled together to directly output a standard signal of DC current (or f

requency), which actually becomes an electromagnetic flow transmitter. The integrated design shortens the connection length between the signal line and excitation line, and makes it externally connected and concealed inside the instrument, thereby reducing signal attenuation and spatial electromagnetic wave noise intrusion. The same measurement circuit can measure liquids with lower conductivity compared to the split type. The wiring of signal lines and excitation lines has been cancelled, simplifying electrical connections. The instrument price and installation cost are relatively cheap, and it is more commonly used in small diameter instruments. With the commercialization of second-line instruments, integrated instruments will have rapid development. However, if installed in a location that is not easily accessible due to pipeline layout restrictions, maintenance will be inconvenient. In addition, the electronic components of the converter installed on the pipeline will be greatly limited by fluid temperature and pipe vibration.

2. Classification based on whether the electrode of the flow sensor is in contact with the measured liquid

1. Contact type electrode - the electrode in contact with the liquid is a habitual structure of EMF, usually a pair of electrodes. Large aperture electromagnetic flowmeter instruments use two pairs of electrodes.

. Non full tube EMF also uses 3 pairs of motors or strip electrodes.

2、 Non contact electrode - a large-area electrode that closely adheres to the outer surface of the lining (or insulated measuring tube), detects flow signals through capacitive coupling, and can measure electromagnetic flow meters that are more capacitive than contact electrodes. The preamp
