Description
SPIRAX SARCO ELM Electromagnetic Flowmeter
SPIRAX SARCO Electromagnetic Flowmeter
An electrically conductive medium induces a voltage while flowing through an arranged magnetic field in accordance to the Faraday’s induction law.A magnetic inductive flowmeter consits of an isolated lining tube, flown through by a conductive liquid, a magnetic field coil and two electrodes. The electrode measuring-circuit voltage is proportional to the flow velocity and therefore to the volume flow.The electrode voltage is detected by a transmitter and converted into standard electrical signals as 4-20 mA or pulses.The magnetic-inductive flow sensor EP is used to measure the volume flow of liquids, slurries, pastes and other electrically conductive media without any pressure drop.Pressure, temperature, density and viscosity do not affect the volume measurements.Portions of solid particles and small gas bubbles should be avoided.
