Flow meter scale installation requirements and environmental factors should be considered

Abstract: the flow meter scale installation requirements and environmental factors to be considered for the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Must be noticed when the installation 1, flowmeter installation problems flow meter of the principle of the different requirements are not the same. For some flow meter, such as differential pressure flowmeter, speed meter, according to the rules in the upstream or downstream of flowmeter should be equipped with a certain length. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a meter scale installation requirements and environmental factors to be considered for the article details. Must be noticed when the installation 1, flowmeter installation problems flow meter of the principle of the different requirements are not the same. For some flow meter, such as differential pressure flowmeter, speed meter, according to the rules in the upstream or downstream of flowmeter shall be equipped with a certain length or long straight pipe, to ensure that the inlet flow meter is before the fluid flow to achieve full development. And some flow meter, such as the displacement meter and flow meter, the length of the straight pipe, there is no demands or lower. And the flowmeter due to affected by the installation of certain error, for example, the coriolis mass flowmeter, because of the effect of installation stress can bring a great error to use. Traces the flow meter in use there is a problem, may all is because the meter itself, not a lot of situation is caused due to improper installation. General common problems are the following: (1) the surface orifice differential pressure flowmeter import against loading; (2) the flow sensor installed on the velocity distribution profile bad places; (3) connected to the differential device of pressure pipe in existing now don't want to phase; (4) flow meter installed in harmful to the environment or not easily accessible places; (5) flowmeter flow direction installation errors; 6 meter or electrical signal transmission lines under strong electromagnetic field; All landowners will be vulnerable to interference flow meter installed in vibration on the vibration of pipeline; Today lack the necessary protective accessories. 2 meter, installation conditions should be paid attention to in the use conditions of adaptability and installation requirements, mainly from the following several aspects to consider, such as the installation of the flowmeter upstream or downstream direction, the direction of fluid flow, pipeline configuration, the valve position, protective accessories, pulsating flow impact, vibration, electrical interference, and the maintenance of flow meter. 1) piping wiring should pay attention to when piping wiring installation direction of the flow meter, because the direction of the installation of the flowmeter installation method generally divided into vertical and horizontal installation, for both installation is distinct in flow measurement performance. Fluid, for example, the vertical downward flow can make additional force flowmeter sensor and impact on the performance of flow meter, lowered the linearity, repeatability of flowmeter. Direction of the installation of the flowmeter still depends on the physical properties of the fluid, such as horizontal line may precipitate solid particles, so I have this state of the flowmeter measurement zui good installation in vertical pipeline. (2) the direction of fluid flow this problem with the direction of flow meter installation is similar, because some of the flowmeter can only work in one direction, reverse flow will damage the meter. Use a similar flow timing to consider when generating operation may reverse flow, so you need to take measures, such as install the check valve to protect the flowmeter. Can even use two-way flow meter, and its measurement performance between forward and reverse may also be some differences, should be used in accordance with the requirements prescribed by the manufacturer. (3) flow meter straight pipe upstream and downstream because of the flowmeter are influenced by the pipeline flow state import, pipe fittings will also introduce the flow disturbance, disturbance usually have a vortex flow and the velocity distribution profile distortion, vortex is widespread because there are two or more than two space ( 3 d) To bend. Velocity profile distortion is usually determined by the local block (pipe fittings Such as valve) Or bend. These effects need to be proper length of straight pipe upstream or installed to improve flow regulator. In addition to consider the effect of flow meter connection accessories, may consider the effect of combination of upstream pipe fittings, because they may have different disturbance source, so be sure to pull open the distance between the disturbance source as far as possible in order to reduce its impact. Such as in a single bend followed by partially open the valve. Flowmeter downstream also needs to have a straight pipe to reduce the downstream flow influence. For volumetric flowmeter and coriolis mass flowmeter is not affected by the asymmetric flow profile congress, Turbine flowmeter should be reduced as far as possible when using vortex; Electromagnetic flowmeter and differential pressure flowmeter should be restricted vortex in a small range. Air-pocket and condensation is caused by pipeline layout is not reasonable, avoid the sharp change of pipe diameter and direction. Piping layout bad also can produce pulse.
