第一章 产品介绍
1.1 产品简介
轻型汽油车简易瞬态工况污染物排放检测系统（简称 Vmas 系统）是基于轻 型汽油车污染物质量排放的测试系统。 与基于浓度排放测试的汽油车稳态加载污 染物排放系统（简称 ASM 系统）相比， Vmas 系统能够直接获取汽车污染物的 排放总质量，可以更为准确地模拟车辆实际的工作状态，更客观、公正地判断车 辆的排放状态。 Vmas 系统由可以模拟加速惯量和道路行驶阻力的底盘测功机、专用五气分 析仪、气体流量分析仪、计算机控制系统组成。用底盘测功机以模拟车辆在道路 上行驶瞬态工况负荷， 用高精度五气分析仪通过采样探头直接获取汽车原始排放 气体 CO、CO2、HC、NOX、O2 浓度值，用流量分析仪测量经过风机抽入流量 测量管稀释气体流量、压力、温度、稀释氧浓度(其中稀释气体由除去进入五气 分析仪的汽车尾气之外，剩余尾气和环境空气混合而成)，通过测量汽车排出原 始气体 O2 浓度和混合稀释气体 O2 浓度计算稀释前后稀释气体的稀释比，可以 得到尾气实际流量，再利用气体状态方程计算出汽油车尾气中 NOX、CO、HC 单位时间（路程）内质量（检测结果为 g/km），可以实时分析车辆在道路负荷 工况下排放气体污染物排放质量，对于全面评价车量的排放状况、估算机动车污 染物排放总质量及制定切实可行的机动车污染物控制规划具有重要意义。 五气分析仪由 CO、CO2、HC 测量平台、NOX 测量平台或电化学传感气、 O2 电化学传感等组成，其作用是用来测量汽车排出原始气体 CO、CO2、HC、 NOX、O2 的浓度。
电击危险！ 为了防止电击危险，使用时，本仪器应适 当地接上地线，但切不要将地线连接在诸如煤气管 道等危险的地方。 本产品执行标准：Q/ZDM 02－2013《 汽车排气流量分析仪》

霍尼韦尔 全自动流量分析仪说明手册说明书
THE NEEDSEvides Waterbedrijf required measurement of turbidity and flow to monitor water quality in the distribution network and manage the network. Until recently, this data had been recorded manually and analysed with outdated equipment. This process no longer fitted with the strategic pillar “digitising primary processes” which was an important aim of the Netherlands water provider. Evides Waterbedrijf developed an all-in-one measuring device which allowed them to make all distribution network measurements. During the measurement process, turbidity, flow and GPS location were all recorded and logged in real-time from the field. This data could be used to determine water quality of the distribution network, assess the effectiveness of previously implemented drainage actions and continue to optimise drainage plans. The process being largely automated. The flow meter was part of the total standpipe solution which was lightweight and easy to dismantle in the field.THE SOLUTIONTo support the needs of EvidesWaterbedrijf, Honeywell Smart Energyoffered their Q4000 electromagneticmeter as part of the standpipe solution.Featuring high quality design andengineering, Honeywell’s Q4000electromagnetic water meter is builtfor maintaining highly accurateperformance and lasting durabilityin demanding environments.With an unrestricted flow tube with nomoving parts and a 10-year batterylife, the Q4000 offers unrivalledperformance for an electromagneticwater meter. Delivering consistentaccuracy over a wide flow-ratemeasuring range, the meter can beadapted to suit either predominantlyhigh or low flow rates, and is ideal fordistribution network applications.The Q4000 is a high-performingelectromagnetic meter, ideal for networkmanagement and leakage monitoring.HON EYWELL’SW A TER M ETERCase StudySupports Accurate Real-Time Distribution Network AnalysisGood quality water supply is provided for the entire population in the Netherlands. Water consumption is one of the lowest in developed countries at 128 litres per capita per day and water leakage in the distribution network is one of the lowest in the world at only 6%.The Q4000 water meter forms part of the total standpipe solution.The Q4000 from Honeywell Smart Energy is a high-performing electromagnetic meter, ideal for bulk flow metering applications such as network management and leakage monitoring.-It has a fast continuous sampling rate, providing highly accurate and reliable measurement.-The Q4000’s extremely tough stainless steel constructionensures a long working life, while its lightweight body makes storage, transportation and installation both simpler and safer.-With an unrestricted flow tube, the Q4000 ensures minimal pressureABOUT EVIDES WATERBEDRIJFEvides Waterbedrijf supplies safe and clean drinking water 24 hours a day, 365 days a year to 2.5 millioncustomers and the business community in Zeeland, in the South West of Holland and the Brabantse Wal.Additionally, Evides Waterbedrijf offers tailor-made industrial water services to large industrial customers in the Netherlands, Belgium and Germany.THE BENEFITSloss, even at the highest flowrates, resulting in reduced network system pressures, helping to prevent leakage from burst pipes. -A large, bright and easy-to-read LCD, showing volume and instantaneous flow rate, is ideal for real-time network control and water management. -With the Q4000’s 10-yearcontinuous battery life and no need for calibration, expensive regular maintenance is a thing of the past. -With bi-directional pulse outputs, the Q4000 provides dependable connectivity to critical water management systems including AMR and data logging devices.All rights reserved.The company’s policy is one of continuous product improvement and the right is reserved to modify the specifications contained herein without notice.

流量检测仪使用说明书
Flo-Tech, PFM6 流量压力检测仪使用说明书流量压力检测仪的使用要领1. 检测仪各部名称（图1）涡轮流量计各部名称（图2）2. Flo-tech检测仪参数* 为现用检测仪(1) 检测仪使用要点本检测仪操作简单，不需要特殊练习，就可以立刻使用。
为了正确的判断试验结果，有必要事先了解测试对象的液压系统和各液压执行部件，掌握必要的资料，比如：操作压力、流量、溢流阀设定压力、液压泵的最高输出压力、液压泵的性能曲线等。
①液压软管的连接检测仪如上表所示有三种机型，其软管的连接分两种类型a、PFM6-50、PFM6-85为1英寸的PT内螺纹。
b、PFM6-200上附有1英寸PT螺纹的连接器。
90°的管接头、T型管接头、阀等距离检测仪的输入端最好在30cm以上，因为这些部件将会给流体的测量带来误差。
软管的另一侧（与被测机器连接侧）通常与连接检测仪一侧为相同连接螺母，所以当管径或螺纹不同时，请利用转接器。
②操作要领检测仪的操作是简单的，但误操作将会给检测仪或被测试机器、回路带来不良影响。
使用者在使用前请读熟本使用说明书，避免误操作，以提高测试效率。
a、转换开关通常在中央位置（OFF）测试流量时请放在（FLOW）档位测试油温时请放在（TEMP）档位测试结束后，请勿必将开关拨回到OFF位置。
干电池使用过期电压下降时，仪表（流量、温度计上的冒号：）将发生闪烁。
此时，请更换干电池。
b、认真确认软管是否已正确无误地连接在检测仪的输入、输出端。
检测仪可以并列接入高压侧，但流向若是接反则不能测量正确的流量。
c、液压回路动作前，应将加载阀反时针方向旋转打开。
d、加载阀可以用手简单地进行操作，在加压和卸压时，请缓慢地进行操作。
e、液压回路动作停止之前，要将加载阀打开，确认压力是否已降到零。
在进行多项压力测试时，每一次测试结束，也都应该将加载阀先打开，然后进行下一个项目的测试。
f、安全圆片是保护检测仪和液压机器的，测试时，请密切注意压力表的读数，使之不要超过回路的最高压力。
