The law of electromagnetic flow meter scale selection and installation

Abstract: the law of electromagnetic flow meter scale selection and installation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flowmeter selection and installation of the law: one, the first clear the measurement demand of this unit should be clear several measurement demand, mainly include: measurement of the medium, flow (m3 / h Small zui, operating point, zui) ℃, medium temperature and medium pressure MPa, device. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the law of electromagnetic flow meter scale selection and installation details. Electromagnetic flowmeter selection and installation of the law: one, the first clear the measurement demand of this unit should be clear several measurement demand, mainly include: measurement of the medium, flow (m3 / h Small zui, operating point, zui) ℃, medium temperature and medium pressure MPa, device ( Pipeline or into type) And so on. Second, choose ( Electromagnetic flowmeter) Conditions condition 1, it is necessary to measured medium is the conductivity of the liquid ( That demand the fluid being measured zui low conductivity of limit) 。 2, should not contain more measured medium ferromagnetic media or a lot of bubbles. Third, should know the measurement principle of the measurement principle of electromagnetic flowmeter based on Faraday's law of electromagnetic induction, the measurement of flow when the fluid flows through the direction of the magnetic field perpendicular to the activity, and the induction of a conductive fluid activities and uniform velocity ( Also known as volume flow) Proportional to the voltage, the voltage signal through two electrodes directly touch with fluid detection, and through the cable to the amplifier, and then to transform it into an output signal. Four electromagnetic flowmeter, should know the main features of its main features are: (1) the basic measurement tube without the loss of pressure, not easy jam, measurement of serum have a common adaptability; 2 straight pipe section of the demand is low; (3) low frequency rectangular wave excitation, is not affected by power frequency and field distribution simply, operation safe reliable; (4) transmitter body can adopt stainless steel, equipped with fabric information with acid proof, alkali proof, corrosion resistance ability; 5] scene appeared type converter can be used for smart chip, parameter setting is convenient; [6] transmitter inside can set a self-correcting system, may at any time to self-calibration of transmitter and constant calibration values, easy debugging and maintenance; Once measurement scale wide, full scale velocity is set at 0. 3 m / s - 12 m/s scale; Being its into type can device or under the continuous flow condition apart; 'levies scale widely used: can be used in chemical industry, metallurgy, papermaking, food, petroleum, urban water supply, etc. Five, the type of selected key 1, the first clear is choosing pipeline ') Electromagnetic flowmeter ') Or in type electromagnetic flow meter. 2, usually choose the scene appeared no type electromagnetic flowmeter, the output of 4 - 20mA( Or 0 - 10mA) Current signal to the control room of the second appearance and can show the flow rate and total amount. 3, if is advantageous for the site operation when investigating the pipe flow, can choose the type of electromagnetic flowmeter. 4, in the environmental requirements or measurement precision demand is high, can choose safe voltage intelligent electromagnetic flowmeter. 5, in more than 200 mm diameter measurement flow or continuous flow conditions, installation give priority to choose in type or enhance in type electromagnetic flow meter. Six key 1, the selection of sensors, sensor size selection of caliber pipe size and cohesion of the same technology, its advantage is convenient device ( Don't need reducer) ； The condition that the flow velocity of fluid inside should be 0. 3 m / s - Within 10 m/s scale; Its applicable conditions for early use and lower fluid velocity inside. 2, select the calibre of the sensor and the cohesion of the technology is not the same as the pipe size, its applicable conditions: (1) low flow velocity, flow stability: 2 drop ratio: seven, fabric material selection of key according to the company of the measured medium corrosion resistance, wear resistance and temperature, selected by subscribers, can see each manufacturer supply & other; Fabric material function and the suitable scale table & throughout; 。 Eight, electrode materials selected on the basis of the company of the measured medium corrosive, selected by subscribers, can see each manufacturer supply & other; Electrode material corrosion resistant function table & throughout; 。 Nine, selected according to the national standard GB4208 - protection grade 84, have protection grade: if the appearance device on the ground and are often flooded under appropriate choosing diving type; If appearance device on the surface of the appropriate selection of the water proof type. Ten, the maximum flow of choose 1, usually select a size and cohesion of the transmitter pipe sizes. Because of the size, velocity and flow exist severe function, can see when choosing manufacturer supply limits of electromagnetic flowmeter flowmeter, under the corresponding size selection ceiling flow value. 2, because the technology with pipe flow is low and sometimes reach & other 1' Zui small cap in the corresponding size of flow value, can choose transmitter size less than the size of pipe technology, namely before and after the transmitter and the reducer. Eleven, choose 1, monolithic device way: line flowmeter sensing some and transformation of an organic whole, strengths is easy device. 2, separation type: some of the sensing device will flowmeter in the pipeline to be tested, indoor will transform to some device to facilitate operation. Apply to the scene environment difference ( But the separation length should be less than 30 m) 。
