Abstract: the intelligent vortex flow meter scale in use the question solution information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Intelligent vortex flow meter in use the question solution in jiangsu embellish instrument production intelligent vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. Its characteristic is small pressure loss, range plan. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the intelligent vortex flow meter scale in use the question solution article details. Intelligent vortex flow meter in use the question solution in the production of intelligent vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. Is characterized by small pressure loss, large range plan, high precision, working condition of the measurement volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity. No moving mechanical parts, so high reliability, small amount of maintenance. Surface parameters can secure for a long time. The surface of piezoelectric stress sensor, high reliability, can be in - Working temperature of 20 ℃ ~ + 250 ℃ within the plan work. There are also signal simulation codes, digital pulse signal output, easy to digital system facilities, such as accounting and machine utilization, is a kind of ling, mutatis mutandis, first aim of the surface of the flow. Intelligent vortex flowmeter in the use of common problems in question is as follows: mainly include: (1) indicates a long time is not allowed; (2) has no instructions; (3) indicates big plans don't firm, 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 the flow changes indicate changes to keep pace with; Was unable to determine the surface coefficient of K, with several data are constructed disambiguation. Solution involves the following aspects: 1, the selection of questions. Some vortex sensor on the diameter selection may change the condition of plan selection in the future due to skills, big - making choice A specification, internship selection should choose maybe small caliber, before into the accuracy of measurement, the reasons mainly related to question (1), (3), 6. , for example, a vortex line plan for several devices to use, because the skills some equipment sometimes don't apply, constitute now practice using flow decreases, and practice using a planned selection diameter is too big, is equal to the forward of the measured flow rate lower limit, skills pipeline little traffic instructions cannot be guaranteed, the large flow can also be used, because the hypothesis to transform from scratch sometimes too difficult. Skills conditions change only temporary. Please contact parameters from setting into instructions before accuracy. Question 2, equipment. Mainly sensor of the straight pipe length, affect the measurement precision of the main reasons related to question (1). Such as: straight pipe in front of the sensor significantly deficient, because FIC203 not used for metering, just used to control, so the precision of the now can use equivalent of relegation. 3, parameter setting direction. As the parameter errors, causing surface instructions is wrong. Parameter error makes the secondary surface full frequency calculation error, its reason mainly related to question (1), (3). Full frequency phase almost makes instructions for a long time, accounting practice full frequency gets full frequency makes the instruction of big plans not firmness, readings, and material parameters on the bifurcation of dispute gay and affected the parameter, after all, determine calibration contact each other through from the beginning, after all, according to determine the parameters, dealt with the question. 4, secondary surface defects. This some defect is more, includes a circuit board has a break the surface of the local, range set a single blink bad, K coefficient set a single blink bad, unable to determine the range setting and K coefficient setting, there are some reasons for this mainly to the relevant question (1), (2). By marking the corresponding shortcomings, questions to be able to handle. Five, four line jobs to answer the question. Some circuits on the surface line connection is wonderful, careful examination, some joint practice were loose form a continuous loop although some joint connection is tight but due to line a doubt fastening screw fastening on the line of leather, also makes the circuit, some reasons for this mainly related to question (2). Deal with the corresponding circuit doubt, existence question and corresponding processing. 6, on the surface of the quadratic surface and the subsequent question. Due to the surface of the follow-up question may be due to the surface of the follow-up maintenance, the secondary surface mA output circuit, for this type of quadratic surface, some reasons for this mainly related to question (2). Especially for the subsequent recorder, damage in a recorder for a long time can't grade, must pay attention to the output of the sub quadratic surface. 7, due to the secondary surface flat cable faults constitute a loop has no instructions. Because of working long hours, and was affected by dust, flat shaft, cable faults, through clean may replace axle wire, questions to be able to handle.
