What types of common electromagnetic flowmeters are there?

The electromagnetic flowmeter is a widely used flowmeter, which can be divided into several different types depending on the intended use, etc. Next, we will talk about the common types.

1. According to the purpose :

In metallurgy, petrochemical, paper, printing and dyeing, textile, water supply, sewage treatment and other industrial uses are generally more sub-body, the large-diameter flange connection; Sanitary: Industrial cheese, food, medicine and biochemistry; diving - - It is used to measure the flow of water under the natural flow of free water in open channels or non-full pipes, such as industrial drainage and sewage.

2 , according to the flow sensor and pipe connection method :

Flange connection - Flange connection is a traditional connection method. There are connection flanges at both ends of the sensor. It is bolted to the pipe flange and can be installed in one direction. The large-diameter sensor of the electromagnetic flowmeter adopts this connection method; the flange clamp connection: the connection method developed in recent years when the flange is clamped and connected, the sensor of the electromagnetic flowmeter itself cannot be blue, and the two bolts are clamped in the pipeline with long bolts. Access to the piping between the flanges.

3. According to the sensor and converter assembly method :

Split-type electromagnetic flowmeter: Split type is the most common form of electromagnetic flowmeter. The sensor is connected to the pipeline. The converter is installed in the instrument room or near the sensor that people can easily access, and is tens to hundreds of meters apart. In order to prevent the intrusion of external noise, the signal cable is usually double-layered; the separate converter can be away from the harsh environment of the site, and it is convenient to check, adjust and parameterize the electronic components. Integrated electromagnetic flowmeter: The sensor and the converter are assembled together to directly output the DC current (or frequency) standard signal, shortening the connection length of the signal line and the excitation line, and making the object externally connected, concealing inside the meter, thereby reducing signal attenuation. And space electromagnetic wave noise intrusion.
