Electromagnetic flowmeter for measuring the volume and the flow of electrically conductive liquids. The absence of internal moving components guarantees maximum measurement accuracy, no maintenance requirement, constant functionality over time and the ability to install the meter in any position. The precision of the measurement is not conditioned by the presence of debris and deposits in the measured fluid and the internal lining of the passage tube, either PTFE or EBANITE, allows the management of a wide variety of chemically agressive liquids.
