Abstract: describes the use and maintenance of vortex flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Weinan and shunda flow meter manufacturer production of vortex flowmeter is mainly used in industrial pipeline medium fluid flow measurement, its characteristic is small pressure loss, wide range, high precision, high reliability, small amount of maintenance and other characteristics, is a more advanced, the ideal flow. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a brief the use and maintenance of vortex flow meter scale article details. Flow meter manufacturer production of vortex flowmeter is mainly used in industrial pipeline medium fluid flow measurement, its characteristic is small pressure loss, wide range, high precision, high reliability, small amount of maintenance and other characteristics, is a more advanced, the ideal flow meter. Technology below small make up for the user to explain it in detail when using vortex flowmeter need to pay attention to? One, the main existing problems of (1) indicating long-term inaccurate; (2) always without instructions; (3) indicates wide fluctuations, not reading; (4) instructions not to return zero; 5. Small traffic without instructions; Today big traffic instructions can also, small flow instructions are not allowed to be; 7 when instructions change to keep up with changing flow; Today K coefficient can not be sure, many data are not consistent. Second, the main problem of analysis and solve the problem of 1, the selection. Some vortex sensor on diameter selection or due to changes in process conditions after the design selection, made the choice big & ndash; Specifications, the calibre of the actual selection should choose as small as possible, in order to improve the accuracy of measurement, the reasons are mainly related to problem (1), (3), 6. 2, installation problems. Mainly sensor of the straight pipe length is insufficient, affect measurement accuracy, its reason mainly related to the problem (1). 3, parameter setting direction. Due to parameter errors, instrumentation instructions is wrong. Parameter error makes the secondary instrument full frequency calculation error, its reason mainly related to problem (1), (3). Full frequency phase almost makes instructions are not allowed to be for a long time, the actual full frequency gets calculation of full frequency makes indicates wide fluctuations, readings, and data inconsistency and influenced the parameters of zui eventually determined, zui end parameters was determined by the calibration compared with each other again, to solve the problem. 4, secondary instrument malfunction. This part of the fault is more, including: an instrument circuit board has break line, range set individual shows bad, K coefficient set individual shows bad, make uncertain range setting and K coefficient setting, this part mainly to the relevant problem (1), (2). With the appropriate repair of fault, the problem is resolved. Five, four line connection problem. Part of the loop line connection is very good on the surface, and check carefully, some loose joint has actually led to the suspension of circuits, although some joint connection is tight but due to line problem tighten screw fastening on the line of leather, also makes the circuit interruption, this part is mainly related to problem (2). Solve the problem of the corresponding line, existing problem and corresponding solution. 6, due to secondary instrument flat shaft cable fault loop always without instructions. Because of long running, and is affected by the dust, causing shaft cable fault, clean or replace flat through wires, axis to solve problems. 7, to question 7 is mainly due to the secondary instrument display meter coil fixed screw loose, causing header sinking, Pointers and surface friction, action is ineffective, and fixed by adjusting the header, corresponding solution. Eight, the use of environmental problems. Especially the sensor installed in the well, in part due to environmental humidity is big, cause circuit board be affected with damp be affected with damp, this part mainly related to problem (2), (2). Through the corresponding technical measures, the part of the environment of high humidity sensor to separate the sensor parts and transformation processing, to switch to the separated type sensors, so the good working environment, has this part of the instrument as well. Question 9, for today is put forward alone, is in a long time to affect the analysis of the problem to solve, because the eastern chemical works, conditions are not available for K coefficient calibration coefficient K can only according to the manufacturer to provide information, some changes due to the manufacturer itself, cause on several data provided by K factor not & ndash; Influence the problem solving. By looking for conditions to re-mark, or by repeatedly modified contrast, zui end of a unified instrument parameters. Third, in order to better use of vortex flowmeters are summarized as follows: 1, regularly check grounding and shielding case, eliminate the interference. The problem is due to interference by sometimes instructions. 2, regular cleaning of vortex street flowmeter should probe, was found in the examination and individual probe test holes have been contamination jams, and even be plastic wrapping, affected the normal measurement. 3, meter data management should cause enough attention, to facilitate the future work. 4, installation environment humid probe. Should be drying time, regularly and moistureproof processing. Because at the end of the probe itself and moistureproof processing, affect running after be affected with damp be affected with damp. Meter factory all staff to & other; Integrity, efficiency, innovation, development, harmony and win-win & throughout; The idea, to promote the development of the technology in the field of responsibility, and to serve the society is the first duty of a, willing to work with people from all walks of life hand in hand, for the cause of China automation to struggle! Constantly strive to create a harmonious society! Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
