What Should I Do If the Reading of the Electromagnetic Flowmeter Is Inaccurate?
Understanding How Electromagnetic Flowmeters Work Before diving into troubleshooting, it helps to quickly review how magmeters work. Electromagnetic flowmeters operate on Faraday’s Law of Electromagnetic Induction: when a conductive fluid passes through a magnetic field, a voltage is induced that is directly proportional to the fluid’s velocity. The key components
