According to the intelligent photoelectric magnetic flow meter, a measured pipeline penetrates through a housing, a magnetic rotor is sleeved on a central shaft in the measured pipeline, and restrainers of the magnetic rotor are arranged at the two ends of the magnetic rotor; a magnetic induction coil with a backbone is arranged outside the measured pipeline in the housing and is connected with the rear end of a linkage device, and the linkage device is fixed inside the housing through a bracket; light emitting and receiving devices are arranged at the two sides at the front end of the linkage device, and a microprocessor system and a display panel are arranged inside the housing; the housing is provided with a display window; and flange plates are respectively arranged at the upper part and the lower part of the measured pipeline. The intelligent photoelectric magnetic flow meter is obvious in measurement accuracy and relatively high in follow-up ability, is capable of measuring gas, liquid, acidic and alkali media and media with different densities and viscosities and has wide application field, considerable market prospect and practical value.

Description

Technical field [0001] The invention belongs to the technical field of instrumentation measurement and measurement, and in particular relates to an intelligent optical electromagnetic flowmeter, which realizes high-precision intelligent processing through a combination of electromagnetic and photoelectric using a microprocessor. Background technique [0002] In the era of rapid development of science and technology, the demand for intelligent instruments has become more and more obvious and gradually replaced older instruments with lower precision. Especially in the field of flow measurement, the structure of the metal rotor flowmeter restricts the improvement of its accuracy, and the metal rotor flowmeter has no remote transmission function that cannot meet the needs of users and restricts the development of the instrument. Although the electromagnetic flowmeter has the remote transmission function, the accuracy is also higher than that of the metal flowmeter, but the meter requ...

AI Technical Summary

Problems solved by technology

Especially in the field of flow measurement, the structure of the metal rotameter restricts the improvement of its accuracy, and the metal rotameter has no remote transmission function, which cannot meet the needs of users and restricts the development of the instrument.

Although the electromagnetic flowmeter has the function of remote transmission, the accuracy is also higher than that of the metal flowmeter, but the instrument requires electrical conductivity for the medium and cannot measure gas, which also restricts the use and development of the instrument.

In addition, orifice flowmeters, V-cone flowmeters, target flowmeters, rotameters, float flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, laser flowmeters, etc. are common technical problems with low precision.
