This paper introduces ABB electromagnetic flowmeter FET300 series and its advantages and disadvantages

Digital and remote control:

Some ABB electromagnetic flowmeters support a variety of Fieldbus technologies, such as Profibus PA, Foundation Fieldbus and Modbus, allowing for remote control and management. At the same time, from the signal conversion, calculation, output to the field setting, debugging, display, etc. all use digital chip design, improve the intelligent level of equipment.

Easy to install and use:

ABB electromagnetic flowmeters are relatively easy to install and use. The instrument uses a wide ambient temperature range, and supports on-site isolation digital button setting, and can be adjusted and set without opening the cover.

shortcoming

Limited application range:

ABB electromagnetic flowmeters can only be used to measure the flow of conductive media, and cannot measure the flow of non-conductive media (such as gas, steam or high-purity water). This limits its use in some specific application scenarios.

High installation requirements:

Since the working principle of the electromagnetic flowmeter depends on the magnetic field, the installation position should be avoided near the strong magnetic field or other electronic equipment to prevent interference. At the same time, good contact should be maintained between the transmitter and the pipe and correct grounding should be carried out to ensure measurement accuracy. These requirements add complexity and difficulty to the installation.

High requirements for fluid cleanliness:

The measurement accuracy of ABB electromagnetic flowmeter is greatly affected by impurities. When the fluid contains more bubbles, solid particles, or dirt, the accuracy of the measurement may be affected. Therefore, the flow meter needs to be cleaned and maintained regularly to ensure that it works properly.

The measurement error may be large:

In some special cases, such as when the conductivity in the fluid changes or there is a gas in the measuring tube, the measurement error of the ABB electromagnetic flowmeter may be large. This requires attention to eliminate these interfering factors in the process of use to improve the measurement accuracy.

In summary, ABB electromagnetic flowmeter has the advantages of high precision, reliability, wide application range and strong anti-interference ability, but at the same time, it also has the disadvantages of limited application range, high installation requirements, high cleanliness requirements for fluids and large measurement errors. The selection and use should be comprehensively considered according to specific application scenarios and requirements.
