正常供气时常用支路工作（主路），备用支 路进出口阀门开启，切断阀开启，调压器处 于关闭状态。
当主路调压器出现故障造成出口压力超过切 断压力时，主路切断阀将主路切断。管路压 力下降，当压力降至备用支路调压器器启动 压力时，备用支路自动启动，保障正常供气。
为了进一步说明，下面举一个栗子 本站各压力设定值如下： 主路调压器出口压力设定为 3.5MPa， 备用支路调压器出口压力设定为 3.4MPa 主路切断阀切断压力设定在 3.9MPa 备用支路切断阀切断压力设定在 4.0MPa 安全阀启跳压力为进口6.0MPa，出口6.4MPa
正常供气时主路工作，保持 的压力供气，当 主路调压器出现故障，造成出口压力逐渐升 高，压力升至 3.9MPa时，则主路切断阀自动 切断，此时两路均处于关闭状态，由于下游 继续用气，出口管路的压力将逐渐下降，当 压力降至3.4MPa时，备用支路自动启动，保 持出口3.4MPa的压力继续供气。此工艺不但 能保证燃气调压管线超压切断和自动切换， 而且在下游超大气量用气，常用支路的输出 气量不能满足需要，出口压力降至3.4MPa时， 备用支路也能自动启动，此时两路同时供气， 以保证用气需求。

OMEGA is constantly pursuing certification of its products to the European New Approach Directives. OMEGA will add the CE mark to every appropriate device upon certification.The information contained in this document is believed to be correct but OMEGA Engineering, Inc. accepts no liability for any errors it contains, and reserves the right to alter specifications without notice.WARNING: These products are not designed for use in, and should not be used for, patient connected applications.InstallationInlet and outlet ends are marked on the flow meter body,and an arrow on the printed scale indicates flow direction.Insite flow meters can be mounted in any convenient orientation (vertical, horizontal or anything in-between)without affecting performance. The end fittings are con-nected to the plastic body with O-ring sealed straight threads and don't need to be highly torqued to prevent leakage. These fittings accept pipe with tapered threads (NPT). Teflon tape should be used on the pipe threads and standard torques applied, to make leak-free connections.Put your wrench only on the end fitting when piping on.Do not apply wrenches on the plastic body alone when connecting to pipe.Many users find that a disconnect fitting, installed upstream of the flow meter, makes for easier removal of the flow meter, for cleaning internals. Control valves should be installed downstream of the flow meters.Two scales are provided. One for liquid and one for air/nitrogen gasses. Air/nitrogen gas meters are calibrated in SCFM. The air/nitrogen scale is calibrated at 90 PSI pressure and 70o F temperature. If the flow meter is used with air at pressures and/or temperatures that differ from the above, correction factors can be applied to a 90-psi air scale readings to get correct SCFM values. See Tables.High pressure air vented to atmosphere through the Insiteflow meter may result in erratic readings. When used to4For Electric Signallingmeter.

DO NOT EXCEED 300 MILLIAMPS BELOW 26 VAC/26VDC. Switch has three wires: Black for normally open, blue for normally closed, and white for common.NOTE: Switch has a 25% of full scale operating band. Within the band, the switch activates. Above and below the band, the switch deactivates. Thus,one switch can be used as a deviation alarm.Model FL-505, FL-510, and FL-515 flow meters can be equipped with one or two electric switches so that any flowrate within the range of the meter can be made totrigger a signal (or signals).Switch settings are easily adjusted. They are supplied in kit form for installation in the field.Order No. FL-500-R I .Model FL-530, FL-540 and FL-550 require switch kit #FL-500-R2.Each switch kit consists of a ring shaped ceramicmagnet that fits around the flow meter piston, and aproximity switch in a housing that clamps to the body of the flowStep 1. Install the magnet. You must disassemble the flow meter to do this. Follow instructions found under theheading “Maintenance” on page 3. Remove piston from the shaft and place the magnet between piston and spring.Be sure that the piston is installed as in the drawing,and the spring is seated on the magnet and piston.Insert into tube and replace outlet end fittings.Step 2. Install the foam gasket. It has an adhesive on one side, covered with a protective paper. Peel off and press the gasket firmly into place on the switch housing.Step 3. Install the switch housing on the flow meter body.(A) If you are installing only one switch, push thecapscrews through the switch housing tabs, and thread them into the half-collars, as shown. Use the washers provided. The nuts may be discarded.(B) If you are installing two switches, match up the tabs on the two switch housings and push the capscrews through both collar tabs. Put the nuts on the threaded ends of the capscrews and tighten. Use the washers provided. (The half-collars and extra magnet may be discarded.)SWITCH INSTALLATIONNOTE: There is no “wrong orientation” of the switchhousing. If you are installing two switch housings, they can both be oriented the same way, as in the photo, or one “up”and the other “down”. Install to suit your needs in wiring and switch adjustment.SETTING THE SWITCH POINTSWith flow meter installed:Simply adjust the amount of flow to move the piston to the level on the indicator where a switch signal is desired, then turn the switch adjustment screw until switch actuates.(Switch moves toward the adjustment screw head as you turn it clockwise. Use an ohmmeter to determine actua-tion.) Repeat for second switch, if you are using two switches.With flow meter NOT installed:Simulate flow by pushing the eraser-end of a pencil (or a similar tool) through the inlet end of the tube, contacting the float, and moving it against the spring pressure until the knife edge of the float is at the desired reading on the scale. (If your unit has a 1/2 in. pipe fitting, remove it to gain better access.) Then, turn the switch adjustment screw till the switch actuates. (Switch moves toward the adjustment screw head as you turn it clockwise. Use an ohmmeter to determine actuation.) Repeat for a second switch, if you are using two switches.When connecting the switch wires, leave enough lead length (as a pigtail) to allow full travel of the switch.5Direct all warranty and repair requests/inquiries to the OMEGA Customer Service Department.

浅谈天然气计量中的二次仪表
浅谈天然气计量中的二次仪表作者：吴静文章来源：网络论文点击数：19 更新时间：2007-7-22 20:01:26一、二次仪表的产生背景及其由来人们对自然界的认识很大程度上取决于检测和仪表。
流量的检测计量一直是工业生产中过程控制的重要组成部分之一，它与国民经济、国防建设、工业生产、科学研究有密切的关系。
特别是在能源高度紧张、工业生产自动化程度愈来愈高的当今世界，世界各国都在加紧开发新能源来代替传统的煤、石油等一次能源。
与此同时，天然气工业得到了蓬勃发展，伴随着天然气在各国一次能源中的比重不断上升，天然气的计量引起了人们的特别关注，在天然气的采集、处理、储存、运输和分配过程中，需要数以百万计的流量计，其中有些流量计涉及到的结算金额数字巨大，对测量准确度和可靠性要求特别高。
天然气的计量关系到每个用气的公司、个人的切身经济利益。
由于天然气是一种可压缩性流体，作为一次检测仪表的流量计本身仅仅能够检测工况下的气体体积量，无法给出统一状态下的气体体积量，给天然气的贸易计量带来很大的不便。
为了更准确的计量，必须有一种可以在线检测气体的温度、压力和流量信号，并进行压缩因子自动修正和流量自动跟踪补偿，将工况体积量转换成标准状态体积量的仪器，在这种背景下就产生了体积修正仪。
二、体积修正仪的主要功能体积修正仪主要用来在线检测气体的温度、压力、流量等信号，并进行压缩因子自动修正和流量自动跟踪补偿，将工况体积量转换成标准状态体积量的仪表[1]。
具体转换原理为：1、在线检测温度、压力信号；2、检测气体成分(或根据实际情况、设定天然气的气体组分)，然后通过温度、压力信号、气体成分计算出压缩因子[2]；3、接受流量计发出的流量脉冲信号，并根据流量计的出厂校准曲线对流量计的脉冲信号进行自动修正；4、最后通过气体状态方程计算出标准状态下的流量值，并直接显示计算结果进而达到商业计量的需要。
此外，作为一种现场检测仪表，随着自动化水平和现场总线技术的不断提高，要求体积修正仪具有存储、显示、通讯等功能，部分用于贸易结算的体积修正仪还要求具有打印、计算金额等功能。

If you have any problems with the meter, refer to the maintenance and troubleshooting sections of this manual.If you need further assistance, contact Omega’s customer service department by telephone or fax for advice.2.SpecificationsService Fluids: Clean liquids, max particle size .125" Accuracy: ± 0.25% of reading or better above 100 cstk Repeatability:± 0.05%Flow Range:w/ Mag Coil Pickup 2 to 20 GPMw/ Hall Effect Pickup 0.02 to 20 GPMK-factor: 460 pulses per gallon (approximate)Operating Temperature:w/ Mag Coil Pickup: -268°C to +232°C (-450°F to +450°F)w/ Hall Effect Pickup: -40°C to +150°C (-40°F to +302°F)Operating Pressure: 3000 PSIG standardMinimum Fluid Viscosity: 100 cstkWetted Parts: 316 SS body and gears with peek gear seats Bearings: Shielded, self lubricating 440 SS ball bearings Connections:Flange Option: 1" MNPT STDPickup Coil: Magnetic Type or Hall Effect (6 to 24 vdc power) Calibration: 10-point calibration traceable to NIST @ 100 cstks3.Operation3.1PrincipleThe FTB3000 Series of positive displacement meters use a pair of smooth oval rotors to provide a reliable and highly accurate measurement of flow. The smooth oval rotors displace a precise volume of fluid which is passed through the measurement chamber during each revolution. The smooth oval rotor design along with the viscosity of the fluid provides a complete viscous seal within the measurement chamber.The unique patented design ofOmega’s Oval Gear meterincorporates two smooth ovalrotors 90 degrees out of phase.The phase relationship of therotors is maintained by twooval timing gears which areout of the flow path. The ovaltiming gears have a pitchdiameter equal to the outsidediameter of the smooth oval rotors.The flow through the meter measurement chamber follows the path of least resistance. Therefore no liquid passes through the center cavity between the rotors. The fluid is displaced from the inlet to the outlet via the area between the smooth oval rotors and the inner diameter of the meter housing.3.2Precautions▪Before use, confirm the fluid to be used is compatible with the meter and make certain that the operating conditions conform to the meter specifications.▪To prevent damage to the meter slowly fill the system with fluid (this will prevent damage that may be caused by air purge).▪Keep the flowrate within the meter ratings.▪Remove meter from the piping, replacing with a short pipe, when cleaning the piping system by flushing. Costly damage to the meter may result if the assembly is cleaned by flushing with the meter installed.4.Installation▪Use thread sealant on all pipe threads.▪Install the meter carefully to avoid pipe strains.▪The meter must be installed on the discharge side of the pump.▪In tank-head operation, the head of the fluid must be higher than the pressure loss of the meter.▪The flow direction must conform to the arrow mark on the meter body.▪The meter must be installed in the correct orientation (see figure below).▪Connect appropriate connector from pick-up from DCS or electronics.Pickup ConnectionsStandard MAGHall Effect(Open Collector) Redi-Pulse(Open Collector)A - Signal (+)B - Common (-)A - 8 - 30 Vdc (+)B - Common (-)C - Pulse OutputA - 3.5 - 24 Vdc (+)B - Common (-)C - Pulse Output5.Maintenance5.1GeneralThe Omega FTB3000 Series flowmeters do not require routine maintenance and do not contain any field serviceable or replaceableparts.5.2Trouble ShootingRefer to the following troubleshooting guide for assistance withpossible meter malfunctions:TROUBLE CAUSE REMEDYFluid will not flow through the meter ▪Meter installedwith incorrectorientation.Re-orientate the meter.▪Line to meterblocked.Clear line to meter.▪Insufficientdifferentialpressure.Increase upstreampressure.Reduced flow through the meter ▪Line to meterpartially blocked.Clear line to meter. ▪Insufficientdifferentialpressure.Increase upstreampressure.Meter readings inaccurate ▪Fluid flowrate istoo low.See “Specifications” formin and max flowrates. ▪Fluid viscosity toolow.Check fluidspecifications.▪Air in fluid.

02-TBQZ系列气体涡轮流量计
TBQZⅡ/TBQZ/TBQ型气体涡轮流量计一、概述TBQZⅡ/TBQZ/TBQ型为不带机械计数器的两大系列气体涡轮流量计，因配置流量积算仪型号不同，分TBQ型气体涡轮流量计和TBQZ型智能气体涡轮流量计。
其工作原理是：当气流进入流量计时，首先经过特殊结构的整流器并加速，在流体的作用下，涡轮克服阻力矩和磨擦力矩开始转动。
当力矩达到平衡时，转速稳定，涡轮的转速与气体流量成正比，并通过旋转的发讯盘上的磁体周期性地改变传感器磁阻，从而传感器输出与流体成正比的脉冲信号。
TBQ型直接显示工况流量和体积总量；TBQZ型和TBQZⅡ型流量计带温度、压力修正功能，将工况流量和体积总量直接转换成标准状态下的流量和总量。
流量计采用功能强大的新型微处理器，运算精确度高，性能可靠，微功耗，内外电源自动切换工作，锂电池供电可使用五年以上。
产品主要性能指标达到国际先进水平，是石油、化工、电力、冶金工业与民用锅炉等燃气计量和城市天然气、燃气调压站计量及燃气贸易计量的理想仪表。
当TBQZⅡ型配置TFC型修正仪时，可实现GPRS 或短程无线数据传输，组网方便。
产品主要性能参数符合GB/T1894-2003/ISO9951：1993标准，产品荣获国家级新产品称号。
产品执行国家检定规程JJG 1037-2008《涡轮流量计检定规程》和企业标准Q/TX11-2008《气体涡轮流量计》。

~l号，提醒用户更换电池。
但此时并不影响流量计的正常运行，用户应在电池欠压标志出现后的一个星期内更换电池。
在三线制供电时背景光有效，背景光亮度分三级可调。
可通过面板按键中“数据[DAT]”键进行循环调节，调节顺序依次为“亮”、“较亮”、“暗”。
2.流量计累积数据的保存流量计在断电时（无论内外部供电），所显示的累积流量都会瞬间保存在流量计的存贮单元中，以防止意外断电造成的漏计现象，且所有的运行参数也会保存。
待供电恢复流量计又将正常运行。
3.面板按键的使用面板上共四个功能键，分别为设置键[SET]、移位键[MOV]、数据键[DAT]、复位键[RST]，各键功能如下：■设置键[SET]：进入流量计“设置模式”。
■移位键[MOV]：“运行模式”下用于进入“历史数据查询模式”，在“设置模式”下用于执行设置位的移位。
■数据键[DAT]：“运行模式”下用于设置背景光亮度（此时流量计已由外部三线制DC+24V供电，否则无效），在“设置模式”下执行设置位的数据设置。
■复位键[RST]：“运行模式”下用于锁定/解锁显示屏下屏的显示数据（即控制显示屏下屏数据的固定显示方式或循环显示方式），在“设置模式”下则为切换到“运行模式”（此时如果参数有所更改将会自动保存）。
4.红外遥控器（可选）的使用红外遥控器共8个按键分别为：“1”、“2”、“3”、“4”、“5”、“6”、“△”、“▽”，各键功能为：“1,5”键等同xx:xx XX-XX-XX 显示第1次的断电时间记录如果断电次数超过5次，那么第6次的断电时间记录将覆盖第1次的断电时间记录，第7次的断电时间记录将覆盖第2次的断电时间记录，以此类推。

气体涡街流量计工作原理参考资料
江苏荣丰自动化仪表有限公司RFLU系列气体涡街流量计主要用于工业管道中蒸汽介质流体的流量测量，气体涡街流量计特点是压力损失小,量程范围大,精度高,在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。
无可动机械零件，因此可靠性高,维护量小。
仪表参数能长期稳定。
气体涡街流量计采用压电应力式传感器,可靠性高,可在-20℃～+250℃的工作温度范围内工作。
有模拟标准信号,也有数字脉冲信号输出,容易与计算机等数字系统配套使用,是一种比较先进、理想的流量仪表。
一、工作原理在蒸汽流体中设置三角柱型旋涡发生体，则从旋涡发生体两侧交替地产生有规则的旋涡，这种旋涡称为卡门旋涡，如右图所示，旋涡列在旋涡发生体下游非对称地排列。
设旋涡的发生频率为f，被测介质平均流速为，旋涡发生体迎流面宽度为d，表体通径为D，即可得到以下关系式：f=SrU1/d=SrU/md式中U1--旋涡发生体两侧平均流速，m/s；Sr--斯特劳哈尔数；m--旋涡发生体两侧弓形面积与管道横截面面积之比管道内体积流量qv为qv=πD2U/4=πD2mdf/4SrK=f/qv=[πD2md/4Sr]-1式中 K--流量计的仪表系数，脉冲数/m3（P/m3）。
K除与旋涡发生体、管道的几何尺寸有关外，还与斯特劳哈尔数有关。
斯特劳哈尔数为无量纲参数，它与旋涡发生体形状及雷诺数有关，图2所示为圆柱状旋涡发生体的斯特劳哈尔数与管道雷诺数的关系图。
由图可见，在ReD=2×104～7×106范围内，Sr可视为常数，这是仪表正常工作范围。
当测量气体流量时，VSF的流量计算式为(4)斯特劳哈尔数与雷诺数关系曲线式中 qVn，qV--分别为标准状态下（0oC或20oC，101.325kPa）和工况下的体积流量，m3/h；Pn，P--分别为标准状态下和工况下的绝对压力，Pa；Tn，T--分别为标准状态下和工况下的热力学温度，K；Zn，Z--分别为标准状态下和工况下气体压缩系数。
