Electromagnetic flowmeter is a widely used flowmeter, which can be divided into several different types according to its usage. Next, we will talk about the common types.

1. Classified by purpose:

In industries such as metallurgy, petrochemicals, papermaking, printing and dyeing, textiles, water supply, and sewage treatment, split type medium and large-diameter flange connections are generally used; Hygiene type: industrial fields such as cheese, food, medicine, biochemistry, etc; Submersible type - used to measure the natural flow of water in open channels or non full pipe culverts, such as industrial drainage and sewage.

2. Divided by the connection method between flow sensors and pipelines:

Flange connection - Flange connection is a traditional connection method, where the sensor has connecting flanges at both ends, which are fixed to the pipeline flange with bolts and can be installed unidirectionally. The large-diameter sensors of electromagnetic flow meters all use this connection method; Flange clamp connection: Flange clamp connection is a connection method developed in recent years. The sensor of the electromagnetic flowmeter itself does not have a flange and is clamped between the two flanges of the pipeline with longer bolts to connect to the pipeline system.

3. According to the assembly method of sensors and converters:

Split type electromagnetic flowmeter: Split type is a commonly used form of electromagnetic flowmeter, where the sensor is connected to the pipeline and the converter is installed near the sensor in the instrument room or easily accessible to people, at a distance of tens to hundreds of meters. To prevent external noise from entering, signal cables usually use double-layer shielding; The separated converter can be kept away from harsh on-site environments, making electronic component inspection, adjustment, and parameter setting more convenient. Integrated electromagnetic flowmeter: The sensor and converter are assembled together to directly output a DC current (or frequency) standard signal, shortening the connection length between the signal line and the excitation line, and making it externally connected and concealed inside the instrument, thereby reducing signal attenuation and spatial electromagnetic wave noise intrusion.
