Introduction
- Electromagnetic Flowmeter (OEM) follow the Faraday law of electromagnetic induction. They can be used to accurately measure the flowrate of liquids which are electrical conducting, caustic, and mixed with liquids and solids. They are widely used throughout industries of petroleum, chemical engineering, pharmacology, papermaking, electric power, environmental protection and so forth. Their antiknock level is ExdIIBT4.
Structure
- Electromagnetic flowmeters are made up of sensor and transducer, together with LCD screen, current and pulse output, alarm signal and RS-485 communication.
