Introduction to electromagnetic flowmeters commonly used in life

There are many kinds of electromagnetic flowmeters, and generally only two are split electromagnetic flowmeters and plug-in electromagnetic flowmeters. Next, we will introduce the basic information of the two flowmeters.

One: split electromagnetic flowmeter:
The split electromagnetic flowmeter is the most commonly used form of electromagnetic flowmeter. The sensor is connected to the pipe, and the converter is placed in the instrument room or near the sensor that is easily accessible by people, tens to hundreds of meters apart. To prevent intrusion of outside noise, signal cables usually use a double-core shielded cable. When measuring the liquid with low conductivity and the distance is more than 30m, in order to prevent signal attenuation caused by part of the capacitance of the cable, the inner layer shielding also needs to be shielded and driven by the same potential and low impedance source as the core. The split-type electromagnetic flowmeter has a converter that can be kept away from the harsh environment of the site, and electronic component inspection and parameter setting are convenient.
application:
The split type electromagnetic flowmeter has the characteristics of simple structure, light weight, high precision, good reproducibility, sensitive response, convenient installation and maintenance, etc. It is widely used in petroleum, chemical, metallurgy, water supply, papermaking and other industries, and is a flow metering and energy saving. Ideal instrument.

Two: plug-in electromagnetic flowmeter:
In the national economy, such as industry, agriculture, water conservancy, environmental sewage monitoring, urban water supply and other departments to measure the flow and total amount of various conductive liquids. The plug-in electromagnetic flowmeter features both a ducted electromagnetic flowmeter and a plug-in flowmeter.
application:
Plug-in electromagnetic flowmeter is widely used in petrochemical, steel metallurgy, water supply and drainage, water irrigation, water treatment, environmental sewage control, paper, medicine, food and other industrial and agricultural production process flow measurement and control. It can measure the flow rate of acid, alkali, salt solution, water, sewage, corrosive liquid, mud, slurry, pulp, etc. with conductivity ≥5μs/cm.

The above is the basic information of the split electromagnetic flowmeter and the plug-in electromagnetic flowmeter. I hope it will be useful to everyone.
