Coriolis forces. These forces are always present when both translational and rotational movements are superimposed.F C = 2 · ∆m (v · ω)F C = Coriolis force ∆m = moving mass ω = rotational velocityv = radial velocity in rotating or oscillating systemThe amplitude of the Coriolis force depends on the moving mass ∆m, its velocity v in the system, and thus on the mass flow. Instead of a constant angular velocity ω, the Promass sensor uses oscillation.In the Promass F and M sensors, two parallel measuring tubes containing flowing fluid oscillate in antiphase, acting like a tuning fork. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations (see illustration):•At zero flow, in other words when the fluid is at a standstill, the two tubes oscillate in phase (1).The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the tube oscillations at the inlet and outlet.System balance is ensured by the antiphase oscillation of the two measuring tubes. The measuring principle operates independently of temperature, pressure, viscosity, conductivity and flow profile.Density measurementThe measuring tubes are continuously excited at their resonance frequency. A change in the mass and thus the density of the oscillating system (comprising measuring tubes and fluid) results in a corresponding, automatic adjustment in the oscillation frequency. Resonance frequency is thus a function of fluid density. The microprocessor utilises this relationship to obtain a density signal.Temperature measurementThe temperature of the measuring tubes is determined in order to calculate the compensation factor due to temperature effects. This signal corresponds to the process temperature and is also available as an output.The temperature measurement cannot be used to generate data for invoicing in applications subject to legal metrology controls.Proline Promass 84F, 84M Measuring system The measuring system consists of a transmitter and a sensor. Two versions are available:•Compact version: transmitter and sensor form a single mechanical unit.•Remote version: transmitter and sensor are installed separately.4Endress+HauserProline Promass 84F, 84MEndress+Hauser 5InputMeasured variable•Mass flow (proportional to the phase difference between two sensors mounted on the measuring tube to register a phase shift in the oscillation)•Fluid density (proportional to resonance frequency of the measuring tube)•Fluid temperature (measured with temperature sensors)Measuring range in non-custody transfer modeMeasuring ranges for liquids (Promass F, M):Measuring ranges for gasesThe full scale values depend on the density of the gas.

External forces are absorbed by the construction of the instrument, for example the secondary containment.•The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring system is not influenced by pipe vibrations.•No special precautions need to be taken for fittings which create turbulence (valves, elbows, T-pieces, etc.), as long as no cavitation occurs.•For mechanical reasons and in order to protect the pipe, it is advisable to support heavy sensors.•Please refer to the verification ordinances for the installation conditions of the approval for custody transfer in question.!Note!The necessary steps for creating a measuring system and obtaining approval from the Standards Authorities must be clarified with the authority for legal metrology controls responsible.Mounting locationEntrained air or gas bubbles in the measuring tube can result in an increase in measuring errors Avoid the following locations:•Highest point of a pipeline. Risk of air accumulating.•Directly upstream of a free pipe outlet in a vertical pipeline.Mounting locationDN Promass F [% o.r./bar]Promass M [% o.r./bar]Promass M / (high pressure)[% o.r./bar]8No influence 0.0090.00615No influence 0.0080.00525No influence 0.0090.00340-0.0030.005-50-0.008No influence -80-0.009No influence−100-0.012−−150-0.009−−250-0.009−−o.r. = of readingThe proposed configuration in the following diagram, however, permits installation in a vertical pipeline. Pipe restrictors or the use of an orifice plate with a smaller cross-section than the nominal diameter prevent the sensor from running empty during measurement.Installation in a vertical pipe (e.g. for batching applications)1Supply tank2Sensor3Orifice plate, pipe restrictions (see Table)4Valve5Batching tankDN815254*********)1501)2501)∅ Orifice plate, pipe6 mm10 mm14 mm22 mm28 mm50 mm65 mm90 mm150 mm restriction1) only Promass FOrientationMake sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow (direction in which the fluid flows through the pipe).VerticalRecommended orientation with upward direction of flow (View V). When fluid is not flowing, entrained solids will sink down and gases will rise away from the measuring tube. The measuring tubes can be completely drained and protected against solids build-up.HorizontalThe measuring tubes must be horizontal and beside each other. When installation is correct the transmitter housing is above or below the pipe (View H1/H2). Always avoid having the transmitter housing in the same horizontal plane as the pipe.Please note the special installation instructions! see Page16In order to ensure that the maximum permissible ambient temperature for the transmitter (–20...+60 °C, optional –40...+60 °C) is not exceeded, we recommend the following orientations:m = For fluids with low temperatures, we recommend the horizontal orientation with the transmitter head pointing upwards (Fig. H1) or the vertical orientation (Fig. V).n = For fluids with high temperatures, we recommend the horizontal orientation with the transmitter head pointing downwards (Fig. H2) or the vertical orientation (Fig. V).Special installation instructions for Promass F"Caution!The two measuring tubes for Promass F are slightly curved. The position of the sensor, therefore, has to be matched to the fluid properties when the sensor is installed horizontally .Promass F, installed horizontally1Not suitable for fluids with entrained solids. Risk of solids accumulating.2Not suitable for outgassing fluids. Risk of air accumulating.HeatingSome fluids require suitable measures to avoid loss of heat at the sensor. Heating can be electric, e.g. with heated elements, or by means of hot water or steam pipes made of copper. "Caution!•Risk of electronics overheating! Consequently, make sure that the adapter between the sensor andtransmitter and the connection housing of the remote version always remain free of insulating material. Note that a certain orientation might be required, depending on the fluid temperature see Page15.•When using electrical heat tracing whose heat is regulated using phase control or by pulse packs, it cannot be ruled out that the measured values are influenced by magnetic fields which may occur, (i.e. at valuesgreater than those permitted by the EC standard (Sinus 30 A/m)). In such cases, the sensor must bemagnetically screened (except for Promass M).The secondary containment can be shielded with tin plates or electric sheets without privileged direction(e.g. V330-35A) with the following properties:–Relative magnetic permeability µr≥ 300–Plate thickness d ≥ 0.35 mm•Information on permissible temperature ranges →Page18Special heating jackets which can be ordered as accessories from Endress+Hauser are available for the sensors.Thermal insulationSome fluids require suitable measures to avoid loss of heat at the sensor. A wide range of materials can be used to provide the required thermal insulation.Zero point adjustmentAll Promass measuring devices are calibrated with state-of-the-art technology. The zero point determined inthis way is imprinted on the nameplate. Calibration takes place under reference operating conditions.→Page10ff.Consequently, the zero point adjustment is generally not necessary for Promass!Experience shows that the zero point adjustment is advisable only in special cases:•To achieve highest measuring accuracy also with very small flow rates.•Under extreme process or operating conditions (e.g. very high process temperatures or very high viscosityfluids).Note the following before you perform a zero point adjustment:•A zero point adjustment can be performed only with fluids that contain no gas or solid contents.•Zero point adjustment is performed with the measuring tubes completely filled and at zero flow(v = 0 m/s). This can be achieved, for example, with shut-off valves upstream and/or downstream of thesensor or by using existing valves and gates.–Normal operation → valves 1 and 2 open–Zero point adjustment with pump pressure → Valve 1 open / valve 2 closed–Zero point adjustment without pump pressure → Valve 1 closed / valve 2 openZero point adjustment and shut-off valvesInlet and outlet runs There are no installation requirements regarding inlet and outlet runs.Length of connecting cable Max. 20 meters (remote version)System pressure It is important to ensure that cavitation does not occur, because it would influence the oscillation of themeasuring tube. No special measures need to be taken for fluids which have properties similar to water undernormal conditions.In the case of liquids with a low boiling point (hydrocarbons, solvents, liquefied gases) or in suction lines, it isimportant to ensure that pressure does not drop below the vapour pressure and that the liquid does not startto boil. It is also important to ensure that the gases that occur naturally in many liquids do not outgas. Sucheffects can be prevented when system pressure is sufficiently high.Consequently, it is generally best to install the sensor:•downstream from pumps (no danger of vacuum),•at the lowest point in a vertical pipe.。

FU80-胆机中的战斗机xxxxFU80-胆机中的战斗机经过几个月的努力，先后试验了N种电路，我的FU80终于完成了，由于FU80工作电压高，灯丝电流大11A，发热量大，所以这次比较谨慎，全部过程是用示波器和假负载进行调试的。

为便于调试，我是做了一段1000HZ的音频用电脑播放进行调试。

电路输入级开始用的是6N8P SRPP+6P3P推动，经试验推动不足，实测FU80功率输出只有8~10瓦，如果用CD机播放功率可能大些。

后改用6N9P+6P3P推动，功率略有提高，还是不满意，之后又在另一个声道改用6J4P+6P3P推动，这次增益足够，接上喇叭试听，音量电位器只能转动1毫米，要么是无声，要么是震耳欲聋，调整了6J4P的廉栅极电压到100伏，接上10K 负反馈后，增益降低，用电脑播放一段发烧碟，效果不错，原来6J4P的声音也是这么甜美，点上一只烟，靠在椅子上，凝视着音箱开始慢慢的品位，这时看到音箱前面的一块瓷砖在震动，心想可能是瓷砖松了吧，没有在意，过了一会儿音箱也开始震动，又一想可能是音箱没放平吧，只顾欣赏音乐，仍是没有在意，片刻之后，桌子开始震动，桌上立着的机箱也开始大幅度震动，观看示波器调到最大分辨率波形也未见异常，声音也正常，心想这可能就是寄生震荡吧，如果不是次声波就是超声波，因为是低频，次声波的可能性大些，马上关机，待管子冷却后再次开机，现象依旧，负反馈加大到20K后现象消除，考虑到负反馈太大会影响音质，负反馈还是恢复到10K，重新调整了6J4P的廉栅极电压，发现廉栅极电压调到60伏时比较稳定，调到100伏时就容易产生寄生震荡。

由于买到了第2天的车票，匆忙改完另一声道后回家过春节。

春节过后，仔细分析觉得如果不用变压器偶合，推动级无须用6P3P，于是又改为6N8PSRPP+6N8P/2+6N8P/2两级放大推动，增益足够，功率可以做到90W，效果也是很好，后又改为6N8P/2阴极输出，听感也是不错。
