Abstract: the electromagnetic flowmeter to reduce the effects of bend pipe scale installation method of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Electromagnetic flow meter installed and put into use also will encounter all sorts of conditions in the process, make the measurement produces large error, can't even. This requires the instrument installation and operation personnel, can be used in accordance with the standards of instrument equipment and inspect and maintenance specification. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the electromagnetic flowmeter to reduce the effects of bend pipe scale installation method, the article details. Electromagnetic flow meter installed and put into use also will encounter all sorts of conditions in the process, make the measurement produces large error, can't even. This requires the instrument installation and operation personnel, can be used in accordance with the standards of instrument equipment and maintenance specification for inspection and maintenance. Electromagnetic flow meter as the precision of flow measuring instrument, the installation have comparatively strict requirements, such as the influence of electromagnetic interference of the external world, to the requirement of ground, and to the requirement of front-end and back-end straight pipe are important, but sometimes limited to the site conditions, lead to install cannot reach the ideal state, it requires the instrument installation personnel to take corresponding measures, for on-site installation, adjust and optimize the zui end instrument operation meet the design requirements. Electromagnetic flow meter installed and put into use also will encounter all sorts of conditions in the process, make the measurement produces large error, can't even. This requires the instrument installation and operation personnel, can be used in accordance with the standards of instrument equipment and maintenance specification for inspection and maintenance. Ming yu automatic control equipment for the production of electromagnetic and service for many years, the company's technical staff for the installation and maintenance of the electromagnetic flowmeter has a relatively rich experience, to produce all kinds of situation, a more perfect solution. This article make explanations to this, hope for your help. A, the flow measurement value do not tally with the actual values of check and take measures to 4. The cause of the problem in 1) 2) 3) 4) 5) 4. 2 failure inspection and take measures to 1) Most contemporary sewage flow meter in the factory after the actual flow calibration sensor brand ( Or attach the instruction for use with this form) 2) 3) Check the signal cable system; Check the connection cable to match appropriate? Connection is correct? Whether the insulation down? Usually people check the cause of the problem of the sewage flow meter measuring flow, often ignore the connection between the sensor and the converter cable system, often encounter the following example: a) Will be attached to the whole cable cut off after the reconnect, after using a phase joint inhalation moisture, insulation falling; b) Within the end of the line not handle, shielding layer, outer shielding layer and core signal to each other have short, or short and shell; c) No regulation model ( Or the attached) The cable; d) The length of the cable length more than is conditioned by the liquid conductivity limit; e) Low liquid conductivity sensor and converter are far apart, 4) Especially the proximity sensor set upstream regulator or not fully open the gate, can satisfactorily solve * way is to change the sensor installation location; 5) Detection electrode and the contact resistance between the liquid and electrode insulation; Full of electrical conductivity of 150 & times; 10-6 s/cm's life and industrial water, the electrodes with liquid is about 15 k&Omega contact resistance; Electrode insulation resistance should be greater than 100 MΩ Second, no flow signal output check and take measures to 1. The cause of the problem in 1) 2) Connect cable ( Excitation circuit, signal circuit) 3) 4) 5) 1. 2 failure inspection and take measures to 1) 2) 3) Liquid flow direction must be in accordance with the direction arrow on the sensor shell.
