Electromagnetic flow meter consists of two main parts: electromagnetic flow sensor and electromagnetic flow converter. The main components are the measuring tube, electrode, excitation coil, iron core and yoke, shell. The measuring tube of the sensor is a short non-conductive alloy tube lined with insulating material.
Supmea electromagnetic flowmeter in addition to measuring the volume flow of general conductive liquids, can also be used to measure the strong acid and alkali and other strong corrosive liquids and mud, slurry, pulp, pulp and other homogeneous liquid-solid two-phase suspended liquid volume flow. Widely used in petroleum, chemical, metallurgy, textile, papermaking, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other areas of flow measurement, it is a high-precision, high-reliability and long service life of the flow meter. The measured fluid should not contain more ferromagnetic substances or air bubbles, should be based on the measured fluid temperature, pressure, corrosiveness, abrasiveness and other characteristics of the selection of the appropriate pressure level, lining materials, electrode materials and instrument structure form.
Electromagnetic flowmeter according to national standards GB4208-84 and the International Electrotechnical Commission standard IEC529-76 on electrical and electronic products shell protection level of the provisions of the standard for:
In general, the protection level should be selected according to the actual situation, the sensor installed in the ground above should be selected IP65, IP67. sensor required to be installed in the ground below, often subjected to flooding should be selected IP68, in any case, the electromagnetic flowmeter display parts can not use water or enter the water, so it will lead to damage to the electromagnetic flowmeter.
