Vortex flow meter scale error

Abstract: the scale vortex flowmeter by good reasons for error information flow meter, flow meter production factory to provide you with quotation. Vortex street flowmeter measurement deviation main problems are as follows: 1: selection problems. Some vortex sensor on diameter selection or due to changes in process conditions after the design selection, make choose a specification, the mouth of the actual selection should choose as small as possible. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale error reason article details. Vortex street flowmeter measurement deviation main problems are as follows: 1: selection problems. 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 question 1, 3, 6. , for example, a vortex pipeline design for several devices to use, because the process part sometimes does not use the equipment, the current actual use flow decreases, and the actual use of design model selection of the original diameter is too large, equivalent to improve the measurable lower limit flow rate, process piping little traffic instructions cannot be guaranteed, the large flow can also be used, because if you want to reinvent the difficulty is too big, The change of process conditions is only temporary) 。 Can be combined with the parameters of setting to improve accuracy of instructions. 2: the installation issues. Mainly sensor of the straight pipe length is insufficient, affect measurement accuracy, its reason mainly related to question 1. Reason 3: parameters setting direction. Parameter error makes the secondary instrument full frequency calculation error, its reason mainly related to question 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. 5: four line road connection problems. 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 question 2. Solve the problem of the corresponding line, existing problem and corresponding solution. 6: secondary instrument and subsequent instrument connection problems. Due to the subsequent instrument problems or as a result of the subsequent instrument maintenance, the secondary instrument of mA output circuit interruption, for this type of secondary instrument, this part mainly related to problem (2). Especially for the subsequent recorder, in the case of recorder damaged beyond repair for a long time, it is important to note that the short after the output of the secondary instrument. 7: 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. 8: for 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. 9: use the environment. 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 is mainly related to question 2. Through the appropriate technical renovation measures, the part of the environment of high humidity sensor to separate the sensor parts and transformation processing, separated type switch sensor, so the good working environment, has this part of the instrument as well. 10: because of bad field calibration or change due to the adjustment of the actual situation of then. Or the adjustment after running for a period of time after the scene changes again, cause problems, this part mainly related to question 4, 5. Using the oscilloscope, and combining process operation, readjust. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
