Electromagnetic flow sensor-SN52

Product introduction

SN52 series electromagnetic flowmeter is a major flow meter, composed of two parts, sensor and converter, based on Faraday's law of electromagnetic induction to work, used to measure conductive liquids or two-phase media, the requirements of its conductivity should generally be greater than 5 μS/cm (the original conductivity of the tap water is about 100-500 μS/cm), can be used to measure a variety of acids, alkalis, salt solutions, pulp, pulp, etc., but the media can not contain more ferromagnetic substances and a large number of air bubbles, widely used in petroleum, chemical, metallurgical, light textiles, paper, environmental protection, food and other industrial sectors and municipal management, water supply, food and other industrial sectors. The medium can be used to measure all kinds of acid, alkali, salt solution, pulp, mineral pulp, but the medium can not contain more ferromagnetic substances and a large number of air bubbles, widely used in petroleum, chemical, metallurgy, textile, papermaking, environmental protection, food and other industrial sectors and municipal management, water conservancy construction and other areas of fluid measurement.
-Setting range:1.... .150cm/s (water)
-No obstruction of flow parts in the measuring tube, no pressure loss, low requirement of straight pipe section.
-Sensor can be equipped with a grounding electrode to achieve good grounding of the instrument.
-Positive/reverse bidirectional flow measurement function.
-Converter with LCD backlit display makes reading easy in direct sunlight or dark rooms.
-Converter displays percentage volume flow, actual flow and totalised flow simultaneously.
-The display rotates <90°C when mounted on a tube as standard to improve visibility of the integral flowmeter.
-Converter with self-diagnostic alarm output, alarm output for empty load detection, alarm output for upper and lower flow limits, and output for two-stage flow values.
