Description of electromagnetic flowmeter sensor

Introduction of electromagnetic flowmeter sensor
The outer casing of the sensor is welded by carbon steel. Only the electrode and the lining are in contact with the medium. The flange type flow sensor and the converter can be combined to form an integrated electromagnetic flowmeter or a split electromagnetic flowmeter.
Electrode material: stainless steel 316L, the rest can be customized according to requirements (for example: Hc, Hb, Ti, Ta, Pt)
Lining material: Ne, FEP, PTFE or polyurethane optional
Medium temperature: 0~70°C, up to 180°C according to requirements (Note: subject to temperature characteristics of the lining material)
Housing material: carbon steel, can be customized according to customer requirements (for example: stainless steel SS304)
Protection level: optional IP65, IP67 and IP68
Connection standard: Various standards for flanged pipes (eg BS EN1092-1)
The scope of application of electromagnetic flowmeters contains all conductive fluids, such as hot and cold water for HVAC, fresh water, various corrosive media.
The rare faults in the application of electromagnetic flowmeters are caused by faults caused by the destruction of the components of the instrument itself, and some are faults caused by improper selection, improper installation, environmental conditions, fluid characteristics, etc., such as display shake, accuracy drop, and even instrument damage. . It can be divided into two types: faults that occur during commissioning (debug during commissioning) and faults that occur during normal operation (runtime faults).
The electromagnetic flowmeter is composed of two parts, a transmitter and a converter, and is connected to each other by a connecting line (including an excitation line and a signal line). The transmitter is based on the principle of electromagnetic induction law. As shown in Fig. 1, the measured medium moves perpendicular to the magnetic field line, so an induced electromotive force occurs in the direction in which the medium activity and the magnetic field lines are perpendicular.
