Introduction
The electromagnetic flowmeter uses Faraday’s Law of electromagnetic induction to measure the process flow. The device consists of two units: a detector, through which the fluid to be measured flows and in which
The wetted materials for the LF470 are corrosion resistant ceramic and platinum electrods and are applicable to almost any kind of fluids. The LF470 is a lightweight
