Insertion electromagnetic flowmeters are an essential tool in measuring the flow rate of conductive fluids like water, slurries, and chemicals. The device operates under the principle of Faraday's law of electromagnetic induction, where the voltage is induced in a conductor when it moves through a magnetic field. The primary element of the insertion electromagnetic flowmeter is a pair of electrodes that sense the voltage generated in the conductive fluid.
There are two types of insertion electromagnetic flowmeters: hot tap and full bore. Hot tap insertion electromagnetic flowmeters are installed on an existing pipeline without shutting down the process, while full bore insertion electromagnetic flowmeters require the pipeline to be cut and the device inserted.
The working temperature of the insertion electromagnetic flowmeter must be considered when selecting a manufacturer. This device's temperature range is limited by its internal components, including the electrodes and the flow tube. Most manufacturers offer insertion electromagnetic flowmeters that can work within the range of -10°C to 150°C.
Here are some of the top insertion electromagnetic flowmeter manufacturers:
1. Krohne: Krohne offers a range of insertion electromagnetic flowmeters with various features, such as hazardous area approvals, remote communication, and high accuracy.
2. Endress+Hauser: Endress+Hauser's insertion electromagnetic flowmeters can accommodate flow rates from 0.05 m/s to 10 m/s and are suitable for use in harsh environments.
3. Siemens: Siemens offers a range of hot tap insertion electromagnetic flowmeters that can be installed without shutting down the process. These devices are suitable for use in the wastewater, chemical, and food and beverage industries.
4. ABB: ABB's insertion electromagnetic flowmeters are designed for use in various industries, including water and wastewater treatment and food and beverage.
In conclusion, selecting the right insertion electromagnetic flowmeter manufacturer is crucial to ensure accurate and reliable measurements. Consider the working temperature range and the device's features when making a decision. The manufacturers mentioned above are just a few examples of the many reputable companies in this industry.
