Application fields and product characteristics of sewage flow meter

Abstract: Information on the application fields and product characteristics of sewage flowmeters is provided by excellent flowmeter and flowmeter manufacturers. Application fields and product characteristics of sewage flowmeters: Sewage flowmeters are widely used in petroleum machinery, chemical plants, metallurgical plants, textile technology, food processing plants, pharmaceutical factories, paper mills and other industries, as well as environmental protection departments, municipal management departments, water conservancy stations and other fields . . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the application fields and product characteristics of sewage flowmeters. Application fields and product characteristics of sewage flowmeters: sewage flowmeters are widely used in petroleum machinery, chemical plants, metallurgical plants, textile technology, food processing plants, pharmaceutical factories, paper mills and other industries, as well as environmental protection departments, municipal management departments, water conservancy stations and other fields . Electromagnetic flowmeter is an all-round intelligent flowmeter developed and developed by Jinhu Mingyu automatic control equipment using the highest level of technology at home and abroad. It is very different from the old analog or non-intelligent electromagnetic flowmeter, especially in measurement accuracy, reliability and stability. , use function and service life. The measurement principle of sewage flowmeter is Faraday's law of electromagnetic induction. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. It is mainly used to measure volume flow in conductive liquids and slurries in closed pipes. Including strong corrosive liquids such as acid, alkali, salt, etc. 1. Product features: The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and electrical conductivity; there are no obstructions to flow parts in the measuring tube, no pressure loss, and the requirements for straight pipe sections are low; the nominal diameter of the series is DN15.5 ~ DN3003. There are various options for sensor lining and electrode materials; the converter adopts a novel excitation method, which has low power consumption, stable zero point and high accuracy. The flow range can reach 1503:1; the converter can be integrated with the sensor or separate; the converter adopts a 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming; the flowmeter is a two-way measurement system, Built-in three totalizers: forward total, reverse total and difference total; can be displayed. Zhuang, reverse flow, and has a variety of outputs: current, pulse, digital communication, HART protocol; the converter adopts surface mount technology (SMT), with self-test and self-diagnosis functions; the range confirms that general industrial sewage flowmeters are tested The medium flow rate should be 2 to 4m/s. In special cases, the minimum flow rate should not be less than 0.2m/s, and the maximum should not be greater than 8m/s. If the medium contains solid particles, the common flow rate should be less than 3m/s to prevent excessive friction between the lining and the electrode; for viscous fluids, the flow rate can be selected to be greater than 2m/s, and a larger flow rate will help to automatically eliminate the stickiness attached to the electrode. The effect of stagnation is conducive to improving the measurement accuracy. Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined according to the range of the above-mentioned flow velocity V, and its value is calculated by the following formula: Q=πD2V/4Q: flow rate (㎡/h) D: inner diameter of the pipe V: flow rate (m/h) The range Q of the sewage flowmeter should be greater than the expected maximum flow value, while the normal flow value is slightly larger than the full scale of the flowmeter. 50 is appropriate. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Application Fields and Product Features of Sewage Flow Meters'
