Electromagnetic flowmeter is analysed scale for the installation of a design

Abstract: the electromagnetic flowmeter is analysed scale for the installation of a design information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. A device installed in theory there is no limit to, as long as the measurements of the interior of the tube is filled with medium in the all time. Should avoid installed in May cause interference in the flow measurement signals near electrical equipment; Should also avoid installed in May in a middle. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation of an electromagnetic flowmeter is analysed scale design article details. A device installed in theory there is no limit to, as long as the measurements of the interior of the tube is filled with medium in the all time. Should avoid installed in May cause interference in the flow measurement signals near electrical equipment; Should also avoid installed in May produce induced current in a device. 2, size is usually a device measuring tube inner diameter with adjacent process pipe diameter is the same. If in this case, zui big traffic axial velocity is less than the average manufacturer's recommended value, then you should choose a relatively small unit at a time. Also may be due to other reasons, for example, in order to reduce the cost or more rationalization, and selects the diameter smaller than adjacent process piping device at a time. Process piping and measuring tube diameter matching tolerance meet GB/T18659. 3, electrode position due to any bubbles rising and concentrated at the top of the pipeline, while the sediment will be deposited at the bottom of the pipe, so a device must be installed so that: make the electrodes are not in the position. 4, full package requires a device should be installed in such a position: must be completely filled with liquid to be tested. Otherwise, the accuracy of the measurement carlt factory rules. If necessary, also can install alarm device to maintain normal measurement. Local is a device used to measure, such as the sewage flow measurement, this problem is beyond the scope of this standard, will be considered special. 5, pipe configuration's impact on the velocity distribution of flow disturbance affects a precise data are not necessarily get, but for the majority of electromagnetic flowmeter, not more than 1%, if the performance change is recommended for any flow interference sources ( For example, an elbow) , should be in at least 10 times the diameter of upper electrode level. When inevitably less than the distance, opinion should listen to the factory. Ideally, no matter how flow state, the magnetic field configuration should be consistently make electromagnetic flowmeter calibration coefficient. For using electrode specially configured flowmeter, are likely to do, But if the small electrode is unable to realize. In fact, when the electrode plane of velocity distribution with early school have bigger difference, the electromagnetic flowmeter is likely to appear in the calibration offset. A device configuration of upstream pipe joints, is one of the velocity distribution of the cause of special. When a device with tapered tube connected to the pipe, the influence of the irregular flow state on the calibration coefficient will vary depending on the type of irregular flow ( Vortex, asymmetry, etc. ) And the design of the tapered tube ( Convergence, expansion, the cone Angle size, etc. ) , or to reduce or increase. Vortex flow will also change the calibration system, although the perpendicular to the pipe axis flow component does not affect the traffic, but they may affect the signal. In addition, the result from the different morphology (upstream piping For example, there are a few in different plane bend) And the quantity and distribution of vortex, also hard to predict from the process piping layout. Therefore, when suspected of vortex flow, zui to upstream of a device in a vortex eliminator, some forms of vortex eliminator in ISO7194 instructions. 6, the zero check ( Measures) In order to check the flowmeter zero point, must be guaranteed by the flow of a device is zero, so full of static liquid. However, with automatic zero using synchronous pulse dc excitation of the flowmeter, such measures may not be necessary. Electromagnetic flowmeter, the domestic high-end brand flow meter, in order to meet the needs of customers first, quality oriented, let customers use the rest assured. Customer affirmation, is the power of our progress, efforts to develop new technology, improve product performance, with good quality materials, meticulous quality of product, to ensure that yield detection qualified rate 100%. , only do high-quality goods, customer satisfaction is our motivation. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

In the past few decades, v shape coriolis mass flow meter production has increased because of the use of mass flow meter.

Exceed customers' expectations in the procedures of manufacturing mass flow meter.

rosemount vortex flow meter mass flow meter are used largely for tuning fork liquid density meter such as coriolis mass flow meter emerson.

can be used in a wide variety of ways.
