8800D型涡街流量计在供热计量方面的一些问题及解决方案

8800D 型涡街流量计在供热计量方面的一些问题及解决方案摘要:涡街流量计是根据卡门(Karman)涡街原理研究生产的测量气体、蒸汽或液体的体积流量、标况的体积流量或质量流量的体积流量计。
主要用于工业管道介质流体的流量测量,如气体、液体、蒸汽等多种介质。
涡街流量计的应用,在实际的生产中存在着许多优点,但是也会在应用方面存在一些影响计量准确性方面的问题,下面就存在的一些问题展开阐述,并提供相应的解决方案,仅供参考。
关键字:涡街流量计;旋涡发生体;旋涡频率;小流量切除值;电子装置1选型的匹配对计量准确性的影响(1)选型偏小选型偏小导致热用户用汽时流量超量程上限值,表现为汽流啸叫,声音频率很高。
汽流经过漩涡发生体时,产生的非对称漩涡因汽流流速过快,无法作用于漩涡发生体后的压电传感器,也就无法侦测到正常的漩涡频率(即汽流流速)。
用手操器观察电流信号或者瞬时流量,表现为电流或者瞬时流量在低流量范围内波动很大,并且伴随着汽流的啸叫。
解决方法:更换大口径的流量计,降低用汽时,经过流量计传感器的汽流流速。
无条件的,则在流量计后流量计口径20D处加焊一段缩径短管,限制用汽高峰时的汽流流速,从而达到准确计量的目的。
(2)选型偏大选型偏大导致热用户用汽时流量超量程下限值,表现为表计无流量,而用户在正常用热。
原因是汽流流速过低,达不到汽流经过漩涡发生体时产生漩涡频率的最低要求,也就无法侦测到漩涡频率(即汽流流速)。
解决方法:更换小口径的涡街流量计,保证热用户在正常用汽时的流量计量要求。
2表计管道内异物对流量计计量的影响涡街流量计的测量原理,需要在管道内设置一定宽度的漩涡发生体。
这就决定了对所测量的介质的洁净度要求。
测量介质要求无颗粒,无絮状物,并且在涡街流量计安装投用前对需管道进行彻底地吹扫,排污干净,确保涡街流量计投入运用后,漩涡发生体不被诸如石子、焊渣等异物冲击而磨损,甚至损坏、变形。
特别注意的是,流量计前的阀门安装最好采用带加强内环的金属石墨缠绕垫片,或者焊接阀门。

The calculation includes information about damping, shedding frequency, K-factor, service type, pipe ID, and diagnostics.Resource BlockThe resource block contains physical transmitter information, including available memory,manufacturer identification, device type, software tag, and unique identification.Backup Link Active Scheduler (LAS)The transmitter is classified as a device link master. A device link master can function as a Link Active Scheduler (LAS) if the current link master device fails or is removed from the segment.The host or other configuration tool is used todownload the schedule for the application to the link master device. In the absence of a primary linkmaster, the transmitter will claim the LAS and provide permanent control for the H1 segment.DiagnosticsThe transmitter automatically performs continuous self-diagnostics. The user can perform on-line testing of the transmitter digital signal. Advanced simulation diagnostics are available. This enables remote verification of the electronics via a flow signal generator built into the electronics. The sensorstrength value can be used to view the process flow signal and provide information regarding filter settings.F OUNDATION Fieldbus Function BlocksAnalog InputThe AI function block processes the measurement and makes it available to other function blocks. The AI function block also allows filtering, alarming, and engineering unit changes.The 8800D Flowmeter with F OUNDATION fieldbus comes standard with two AI function blocks (1 block for flow and 1 block for signal strength).Proportional/Integral/DerivativeThe optional PID function block provides asophisticated implementation of the universal PID algorithm. The PID function block features input for feed forward control, alarms on the process variable, and control deviation. The PID type (series or Instrument Society of America [ISA]) is user-selectable on the derivative filter.IntegratorThe standard integrator block is available for totalization of flow.SetupBasic setup requires connecting the transmitter to a fieldbus network or 375 Handheld Communicator. The F OUNDATION fieldbus- compliant host will automatically establish communication with the device.The Rosemount 8800D Flowmeter can be easily configured using the DeltaV system.User-configurable parameters include: tag, scaling and units, service type, damping, process density, pipe inside diameter (ID)(1), and process temperature (1).Tagging information can be entered into the transmitter to allow identification and a physical description. 32-character tags are provided for identification of the transmitter and each function block.(1)Process temperature and pipe ID have known effects on the K-factor. The 8800D software automaticallyaccounts for these effects by compensating the K-factor.Product Data Sheet00813-0100-4004, Rev FACatalog 2008 - 2009Flow-6Rosemount 8800DSpecificationsThe following specifications are for the Rosemount 8800D, Rosemount 8800DR, and Rosemount 8800DD, except where noted.FUNCTIONAL SPECIFICATIONSServiceLiquid, gas, and steam applications.

The PPL is determined using the equation:where:Minimum Back Pressure (Liquids)Flow metering conditions that would allow cavitation, the release of vapor from a liquid, should be avoided. This flow condition can be avoided by remaining within the proper flow range of the meter and by following appropriate system design.For some liquid applications, incorporation of a back pressure valve should be considered.
