PKP DM04, Инструкция по эксплуатации

Страница: 21 / 23

Operating Principle:
Magnetic-inductive flow measurement is based on Faraday´s
law of induction. The liquid to be measured (electrically
conductive) flows perpendicular to a magnetic field. This induces
an electrical voltage in the liquid.
This is picked up by two electrodes inserted in the measuring
tube and further processed by the downstream electronics. The
voltage level is proportional to the flow velocity.
