2基本工作原理德国OTT Parsivel2激光雨滴谱仪的工作原理基础是一个能够发射水平光束的激光传感器。
其变送器和接收器集成在防护罩中。
图2-1工作原理图当激光束里没有降水粒子降落穿过时，最大电压为接收器的输出电压。
降水粒子穿过水平光束时以其相应的直径遮挡部分光束，因而产生输出电压。
我们通过电压的大小来确定降水粒子的直径大小。
降水粒子的下降速度是根据电子信号持续的时间推导出来的。
电子信号的持续时间为降水粒子开始进入光速到完全离开光束所经历的时间。
根据上述的决定量可以推算出降水滴谱、降水类型、降水动能、降水强度、雷达放射率和大气的能见度等信息。
安装在传感器头上的防雾装置能够防止降水粒子偏离防护罩、掉入激光束造成测量误差。

SVM™ Enables You to Certify Your Fuels for Both KinematicViscosity and Density in One GoRelevant for: producers (QC), fuel research, fuel wholesale traders, bulk consumers (e.g. vehicle fleet managers for incoming QC)The Anton Paar SVM™ 3001 allows for reliable determination of both kinematic and dynamicviscosity at all temperatures, which are relevant for diesel fuel. Get precision equal toASTM D445 with significantly less effort for cooling.1IntroductionBesides a number of other parameters, most diesel fuel types must fulfill viscosity specifications according to the respective standards. The SVM™ 3001 Stabinger Viscometer™ provides simultaneous determination of kinematic viscosity and densityaccording to ASTM D7042 (also DIN EN 16896) and D4052. It is an excellent solution for fast andeconomical viscosity measurement at standard as well as negative temperatures. Even for measuring the quality of winter diesel at -20 °C, no external cooling is required.This report describes specifically how to test diesel fuels with the SVM™ 3001 to get data comparable to ASTM D445, DIN 51562, and ISO 3104.2 InstrumentationFor testing diesel fuel at 40 °C, SVM™ 3001 does not need any additional accessories. For measurement at low temperatures, a supply of dry air is required. See chapter 2.1, "Accessories".For the -20 °C measurement of winter (arctic or polar) diesel, no external counter cooling is required. The instrument uses air cooling by an internal fan.2.1Accessories ▪ Glass syringe 5 mL2.1.1Drying facilities▪ Air preparation set dew point -40 °C or▪ Technical nitrogen and an appropriate pressure regulator to limit the maximum pressure to 1 bar The air preparation set allows the filling and cleaning at measuring temperature. Further, it keeps the interior of the instrument permanently dry.Figure 2: Air preparation set dew point -40 °C2.2 Installation For installing an SVM™ 3001 respectively the airpreparation set or a source of technical nitrogen, refer to the SVM™ 3001 Reference Guide.3 Measurement of diesel fuel 3.1Instrument preparationFor measurements in the standard temperature range, no special preparation is required. The cells should be clean, dry, and leak-tight. Perform regular checks and do preventive maintenance.For measurements at low temperatures, remove the measuring rotor. Purge the inside of the cell block for a few minutes with dry air to keep this tube dry. Insert the measuring rotor immediately afterwards and close the measuring cell lock. Now purge the measuring cell with dry air for a few minutes before cooling down to remove any traces of air humidity from the cells.3.2 SettingsFor measurements according to ASTM D7042▪ Method: Standard▪ Precision class: Precise ▪ RDV limit: 0.10 %▪ RDD limit: 0.0002 g/cm³ ▪ Automatic prewetting: yes ▪ Drying time:– built-in air pump, at 40 °C: 70 s– compressed dry air, 0.3 bar, at -20 °C: 60 sFor measurements according to ASTM D4052▪ Method: Standard▪ Precision class: Ultraprecise ▪ RDV limit: 0.10 %▪ RDD limit: 0.0001 g/cm³ ▪ Automatic prewetting: yes ▪ Drying time:– built-in air pump, at 40 °C: 80 s– compressed dry air, 0.3 bar, at -20 °C: 60 sAir preparation set – pressure▪ To prevent the cells from warming up too much when drying, 0.3 bar are sufficient.▪ Slow flow (few liters/min) to keep the interior of the instrument dry. Hose connected to the DRY AIR INTERNAL nozzle on the rear of SVM™ 3001.3.3 CalibrationBefore measuring the samples, perform a calibration. If required, apply a calibration correction to improve the reproducibility. Use a standard in the viscosity range of your diesel fuel samples. This can be a certified standard or a house-internal standard with kinematic viscosity values. In any case, you need reliable kinematic viscosity values at the measuring temperatures.To perform a calibration (correction), refer to the SVM™ 3001 Reference Guide.3.4 Sample preparationIf the sample is not freshly drawn from a production line or other reservoir, you can improve therepeatability by homogenizing the sample before taking the test specimen:▪ Fill approximately 100 mL of sample into a glass flask.▪ Close the flask and the original container immediately to avoid evaporation.▪ Stir the sample on a magnetic stirrer at low speed for approximately 5 minutes.3.5 FillingAlways use a glass syringe.The glass syringe supplied with the instrument has a Luer-Lock connector. Remove the filling hose from the measuring cell lock and attach an adapter Luer/UNF PEEK instead. Ensure that the measuring cells are leak tight, clean and dry.Fill at least 1.5 mL as first filling. After prewetting refill at least 1 mL or until the sample in the waste hose is free of bubbles. Sample volume: typically 5 mL3.6 Cooling times and sample throughput Sample throughput:▪ 40 °C: approx. 12 samples/hour ▪ -20 °C: approx. 8 samples/hourCooling times:Generally, the cooling time depends on the measuring temperature, and the ambient temperature,respectively, on the bath size and performance of the thermostat.When starting from room temperature and using air cooling, the SVM™ 3001 is ready for measurement at -20 °C after approximately 20 minutes.For better cooling performance or higher ambient temperatures (> 25 °C), use an external cooling circulator. Find suitable models in the SVM™ X001 Product Description List.3.7 Cleaning 3.7.1SolventsPetroleum benzine (hydrocarbon solvent, blend of mainly C7, C8, C9 n-alkanes) with a boiling range of 100 °C to 140 °C is a universal solvent for cleaning over a wide temperature range. Use this solvent as first solvent to remove the sample. To improve drying at low temperatures, use approximately 2 mL of n-heptane or n-hexane as second solvent.▪ Typical amount first solvent: 6 mL3.7.2Cleaning guidelinesThere is no special cleaning procedure required, as the sample is rather easy to remove. Consider the following hints:▪ Open the cleaning screen. Observe it during the cleaning procedure. It gives helpful information on the cleaning and drying status of the cells during the entire procedure.▪ Remove the sample from the cells by sucking it back into to syringe. This avoids leaking. ▪ For cleaning, a plastic syringe can be used. ▪ When using a single solvent, it must be volatile enough to dry up without leaving residues in the cells.▪ When using two solvents, perform a final flush with a drying solvent to remove any residues. ▪ Dry the measuring cells until the cleaning value turns green and stays steadily green. ▪For details, see the SVM™ X001 Instruction Manual or Reference Guide.4 ResultsThis report compares measurements of diesel fuel (DF-2) at 40 °C performed with SVM™ 3001(ASTM D7042) and with kinematic glass capillary viscometers (ASTM D445).Table 1: Comparison of ASTM D445 and D7042 results5References▪ ASTM D7042: Standard Test Method for Dynamic Viscosity and Density of Liquids by Stabinger Viscometer (and the Calculation of Kinematic Viscosity)▪ ASTM D4052: Standard Test Method for Density, Relative Density, and API Gravity of Liquids by Digital Density Meter▪ EN 16896: Petroleum products and relatedproducts - Determination of kinematic viscosity - Method by Stabinger Viscometer ▪ EN ISO 3104: Petroleum products -Transparent and opaque liquids - Determination of kinematic viscosity and calculation of dynamic viscosity▪ ASTM D445: Standard Test Method forKinematic Viscosity of Transparent and Opaque Liquids (and the Calculation of Dynamic Viscosity)▪ GOST 33-82 - Nefteprodukty.

About diesel fuelWhat is diesel fuel?Generally, diesel fuel is liquid fuel to power diesel engines used mainly in road vehicles, watercraft, rail vehicles, and stationary engines. It can be produced from different types of feedstocks.Petroleum dieselThis is a hydrocarbon mixture with approximately 8 to 21 carbon atoms per molecule. It is obtained by fractional distillation of crude oil under atmospheric pressure between 200 °C and 350 °C. Additionally, it contains additives. The most common grade is diesel fuel no. 2. An important parameter for the quality of a diesel fuel is the cetane number. The minimum cetane number is 51 according to EN 590. Typically, diesel fuels have a cetane number between 51 and 56. Higher cetane numbers are an indicator of better ignitability of the fuel when injected into the cylinder filled with hot compressed air. Viscosity is generally an important parameter for diesel fuel. Fuel, which is too highly viscous, can cause damage in the fuel pump (e.g. cam and follower wear) due to higher pressure. Too low viscosity may lead to a lack of lubrication. Viscosity also influences the fuel delivery rate and the atomization of the fuel during injection. BiodieselBiodiesel or FAME (fatty acid methyl ester) is an alternative diesel fuel derived from renewable feedstocks such as used cooking oils, rapeseed oil, animal fat, or soybean oil. It is obtained by transesterification. Pure biodiesel is known as B100. Mixtures of biodiesel with petroleum diesel are tagged as BXX, where XX is the percentage of biodiesel in the blend. The advantages of biodiesel compared to petroleum diesel are reduction of most exhaust emissions, improved biodegradability and a higher flash point.By the way – petroleum diesel also contains up to 7 % biodiesel according to country-specific laws.For transesterification, the oils or fats are mixed with methanol or ethanol and other additives. The ester linkages of these oils or fats (triglycerides, esters of free fatty acids) are cracked at normal pressure at approximately 60 °C. Then the fatty acids are transesterificated with the methanol or ethanol. The glycerin formed in this process is separated from the biodiesel. The transesterification process decreases biodiesel viscosity significantly compared to the basic material. The cetane number (a measure for the ignition performance) is increased. Synthetic dieselSynthetic diesel is not the same as biodiesel. It can be produced from any feedstock which contains carbon. This can be biomass, bio gas, natural gas or coal. The raw material is gasified into synthesis gas. After purification, this gas is converted into synthetic diesel fuel by variants of the Fischer-Tropsch process (originally, the Fischer-Tropsch synthesis was developed in the 1920s to produce fuel from coal). Depending on the feedstock, different types of production processes are known: biomass-to-liquid (BTL), gas-to-liquid (GTL), or coal-to-liquid (CTL), respectively. The most common variant is GTL. When using coal as feedstock, a disadvantage is a large release of greenhouse gases.Synthetic GTL diesel is free of sulfur, aromatics, nitrogen and others. It is not toxic and produces significant cleaner emission during combustion than diesel fuel refined from crude oil. Synthetic diesel has a high cetane number of 60, GTL diesel of 75 to 80. These fuels can be used in the same regions where diesel fuel is used, even in arctic zones.Winter dieselIn cold areas, diesel fuel tends to form solid wax particles, which thicken the fuel, clog fuel filters and injectors. Winter diesel uses special additives to lower the cold filter plugging point (CFPP, temperature at which wax particles form). The additives do not prevent the formation of wax particles, but they prevent the formation of large wax flakes. This means that the fuel stays liquid at lower temperatures. Basis for winter diesel can be petroleum diesel, a mixture of petroleum and biodiesel, or synthetic diesel. Depending on the area where it is used, one can distinguish between two types, winter diesel and arctic (polar) diesel.Diesel for cold climate zones is defined via the CFPP. EN 590 additionally states a viscosity limit at -20 °C. Appendix B. Why measure viscosity?Influence of viscosityViscosity is an essential parameter for the correct function of a diesel engine, as it directly influences the operation of the fuel injection system and of the fuel pump. The viscosity of biodiesel influences the lubrication of injection nozzle and injection pump, further the atomization of the fuel.Accurate monitoring of viscosity can serve to evaluate the quality of diesel fuels.Fuel injectionUnder high pressure, diesel fuel is injected directly or indirectly into the combustion chamber of a diesel engine via nozzles. The injection system produces a fine spray of fuel droplets, which evaporate rapidly when mixed with the hot compressed air in the cylinder. Droplet size and spray pattern are directly influenced by the fuel viscosity.If the viscosity is too high, the fuel droplets are not fine enough, which causes a worse combustion, more smoke and higher emissions. Too low viscosity can cause hot start problems or injector leakage.Fuel pump – performance and lubricationA too low viscosity can lead to a lack of lubrication of the fuel pump and consequently to increased wear or a failure. Too high viscosity at low temperatures will lead to problems in fuel conveyance – the higher the viscosity, the harder the pump must work to provide a constant fuel flow rate – and damages of the fuel injection pump (e.g. a seizure).Blending of diesel with biodieselFigure 3: Viscosity depending on biodieselconcentration, shows a summary result at 40 °C for diesel fuels with different contents of biodiesel. The viscosity of the product increases with increasing percentage of biodiesel.Figure 3: Viscosity depending on biodiesel concentrationThe viscosity curves follow a trend of power law according to the following equation (here shown for kinematic viscosity only): Equation 1:y = 2.3559 e 0.0059xy ... kinematic viscosityx ... % percentage by weight biodiesel in diesel fuelThis equation yields the calculation in the below table:Table 2: Viscosity calculation from equation 1This table shows, that if the percentage of biodiesel in diesel fuel does not exceed 5 %, both the limits of ASTM D975 can be met (see Table 3) and theenvironmental quality can be improved by adding 1 to 5 % of biodiesel without negative effects on efficiency and function of the engine.Viscosity parameters and typical viscosities The viscosity parameter for diesel fuels is kinematic viscosity. Depending on grade and usage, it is measured at +40 °C, further for winter qualitiesat -20 °C. The relevant specifications are stated in the respective standards and regulations.Table 3: Diesel fuel types – viscosity specifications* The viscosity limits of the ready blend product of biodiesel with petroleum diesel must not exceed the values given in ASTM D975. ** Maximum kinematic viscosity at -20 °C if the CFPP (cold filter plugging point) is -20 °C or lower. This applies to the CFPP classes F and 0 to 4 (see DIN EN 14214, EN 116/IP 309).Diesel fuel specification standards ▪ ASTM D975: Standard Specification for Diesel Fuel Oils▪DIN EN 14214: Automotive fuels.

Either large viscometer baths for simultaneously testing two or four capillaries, or compact desktop mini viscometers with 10-fold range capillaries. All these low temperature capillary viscometersrequire cooling liquids that stay clear at temperatures even lower than the measuring temperature. Such liquids usually are difficult to handle. They are either expensive (silicone oils) or have a low flash point (methanol) and involve a safety risk. On the contrary, even for testing at -40 °C, the counter cooling liquid for SVM™ 3001 is operated only at -5 °C, which permits the use of a low-price water/glycol mixture. Nor can these glass capillary viscometers perform cleaning and drying at the low measuringtemperatures – condensation is in the way. One automatic mini viscometer solves this problem by heating the apparatus for the cleaning procedure. However fast this is done, it still consumes more time and energy than the SVM™ 3001 with the air drying equipment.The following tables give an overview of the main differences between SVM™ 3001 and low temperature glass capillary viscometers:Table 4: Compare SVM™ 3001 to other viscometer baths。
