FunctionThe radar flow detector FlowJam S indicates the flow of bulk materials which moves through the detection range (fig. 1) at a minimal required speed of 0.1 m/s.The detection is executed by evaluating the Doppler’s effect, thus independent of the flow direction.The material flow, which can be in metallic or non-metallic tubes, ducts, free fall distances and discharge points, is indicated by relays.The sensor distinguishes between two conditions: •material flow•material jam or standstill.FlowJam S can be adapted to extreme process conditions like high temperature by a separating flange equipped with a window especially for microwaves.Fig. 1: Detection range103ø 5230G 1 1/2"Fig. 2: Dimensional drawing2. SafetyThe sensor FlowJam S was designed, built and tested to be safe and was shipped in safe condition. Nevertheless persons or objects may be endangered by components of the system if these are operated in an inexpert manner. Therefore the operational instructions must be read completely and the safety notes must be followed.In case of inexpert or irregular use, the manufacturer will refuse any liability or guarantee.2.1 Regular use•Only original spare parts and accessories of SWR engineering must be used.2.2 Identification of dangers•Possible dangers when using the sensor are marked in the operating instructions.2.3 Operational safety•The sensor must be installed by trained and authorised personnel only.•In case of maintenance-work on the pipe or on components of the FlowJam S-sensor, make sure that the piping is in unpressurized condition.•Switch off the power supply for all maintenance, cleaning or inspection works on the tubes or on components of the FlowJam S.•Before hot work the sensor must be removed from the installation place.•The components and electrical connections must be checked for damages regularly. If a damage is found, it is to be repaired before further operation of the instruments.2.4 T echnical progress•The manufacturer reserves the right to adapt technical data to the technical progress without particular advance notice. If you have any questions, SWR engineering will be pleased to inform you on possiblechanges and extensions of the operating instructions.3. Mounting and installation3.1 Basic remarksFlowJam S has to be mounted at an angle between 45° and 90° to the flow direction of the bulk material.Be careful to mount the sensor in an absolutely vibration-free area and that no parts within the detection range are moving, because this might be detected as a material flow.Moving parts within the area of detection have to be screened.3.2 Installation of the sensor in generalThe installation of the sensor depends on the conditions of the site, thus the sensor can be •screwed directly into an existing thread type G 1 1/2“ (fig. 3) •fixed by a flange (fig. 4)•mounted by means of a pipe clamp (fig. 5)Before installation, make sure that neither the medium temperature nor the pressure within the piping or the container require additional measures like e. g. the mounting of a separating flange pervious for microwaves (fig. 6).When used with non-conductive tubes, detection is carried out via the side of the tube. It is not necessary to make a separate hole into the tube.Fig. 3: Thread mountingFig. 4: Flange mountingFig. 5: Mounting with pipe clampFig. 6: Mounting with separating flange3.3 Installation of the sensor on conveyor beltsIf possible, the installation on conveyor belts is to be executed in the area of the discharge point.If the installation is above a conveyor belt, then the FlowJam S has to be installed at an angle of approx. 70 - 80° (fig. 7), in order to use the changing surface profile of the bulk material flow.Based on the formula for the doppler frequency, the following relation can be pointed on.D f = 2 (V* cos α/C) fo (Fig. 8)V = resulting speedD f = frequency shiftfo = transmitted frequencyα= angle of the sensor to flow direction at the bulk materialAngle approx. 90°; mainly the speed of the change of the damping height is measured.Angle approx. 0°; mainly the material speed is measured.Fig. 7: Installation above conveyor belt4. Electrical connectionThe connection of the sensor and transmitter has to be carried out according to fig. 8 and 9.A maximum length of 300 m cable between sensor and transmitter should not be exceeded.Fig. 8: Wiring diagram for sensor (standard-version: with jumper / high-version: without jumper)Fig. 9: Wiring diagram for DIN Rail electronicFig. 10: Wiring of sensor and DIN Rail electronic5. CommissioningAll operational controls required for the alignment are shown in fig. 11.Control elements:• LED 1: Signal strength • LED 2: Material flow • S1: Switching betweenworking current / closed current • S2: Coarse adjustment of sensitivity • P1: Threshold level • P2: Delay timeSwitch S1The position of switch S1 determines, whether the relay is attracted up or released at material flow.Position ”2” (off) causes alarm in case of material flow: • material flow - relay is attracted- contacts 7 + 8 closed • no material flow - relay is released- contacts 6 + 7 closed Position ”1” (on) causes alarm when there is no material flow: • material flow - relay is released- contacts 6 + 7 closed • no material flow - relay is attracted- contacts 7 + 8 closedLED 1The LED 1 (red) lightning shows the signal strength by its luminosity; that is, no lightning if no reception signal (no material flow, no vibrations, etc.), weak lightning if low and strong lightning if intense reception signal.LED 2The LED 2 (green) lights always up, if material flow is detected; this display is independent of the positionof the switch S1.678Fig. 11: Position of control elementsAdjustment of sensitivityHereto use switch S2, potentiometer P1 and potentiometer P2.The control elements are in the following positions at the delivery (this basis is crucial for thecommissioning):•P1 (fine adjustment of sensitivity): at the left lay, thus insensitive•S2 (coarse adjustment of sensitivity): switch at (on), thus relatively insensitive•Jumper on sensor electronic (coarse adjustment of sensitivity): put on, thus relatively insensitive•P2 (delay time): at the left lay, thus minimal delay of 250 msNow start your machine in order to guarantee material flow. In consequence the LED 1 must glow. If the LED 1 doesn’t glow, then the switch S2 has to be set on (off). If there is still no lightning, then either the sensor has to be aligned differently, and/or the jumper has to be pulled out.Now choose the position of the switch S1 accordingly, if the relay has to be turned (on) or (off) at material flow.Enhance the sensitivity so long until the LED 2 glows and the relay switches (off) or (on).If you interrupt the material flow, both LED lightning must go out, whereas the LED 2 goes out at the latest if the delay time ends.Finally, you can adjust the delay time according to your requirements with potentiometer P2 in the range of 250 ms ... 15 s.6. TroubleshootingIf LED 1 does not light up even at the largest possible amplification, the following points must be checked:•properties of the material flow (see e. g. fig. 7)•positioning of the installation•distance between the sensor and the material flowIf LED 1 lights up without an existing material flow and with minimal amplification adjusted on S2 and P1, it is very likely that the sensor detects the motion of something else or vibrations.Attention: Does the LED 1 lights up continuously, then either there is no connection between sensor and DIN Rail electronic, or the sensor is broken!7. Notice•Avoidance of reflection by vibration or moving line parts•Setting of the amplification by potentiometer P1 until just of the switching threshold (LED 2 glows)9.

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。

This is perhaps the oldest and most widely used principle for flow metering, mainly because of its simplicity and its relatively low cost.The Eletta V-series Flow Monitor is used to control flow of liquids and gases in pipes from 15 mm to 500 mm. Through the adjustable SPDT micro switch it is possible to set one low or high flow alarm to protect expensive equipment in various piping systems. The switching point is highly repeatable, within <2%. The Flow Monitor is insensitive to surrounding magnetic fields and it com-bines the long-standing proven mechanical function with outstanding reliability. Together with an exceptio-nally sturdy and robust design, this makes it extremely well suited for difficult environments.The V-series comes in two measuring ratios designated V1 and V15, which means that the V1 has a flow measu-ring span of 1:2 and the V15 has a span of 1:5.Like all Eletta Flow Monitors the V-series can monitor both liquids and gases.All the Eletta Flow Monitors including the V-series can be fitted to any of the various Eletta Flow Monitor Pipe Sections to suit your application.The Instrument consists of two parts mainly, i.e. the Pipe Section and the Control Unit. The Pipe Section is the part that is to be mounted in the process pipe and the Control Unit is mounted directly (standard) or remote to the Pipe Section.As the Control Unit is pre-calibrated before leaving our production facilities, your can change pipe sections to fit other dimensions and materials than originally orde-red without recalibration.The Control Unit contains the micro switch which can be set to trip anywhere within the measuring range.The Pipe Sections come in Copper alloy, Stainless Steel, Cast Iron and sizes from DN 15/­PN16 (ANSI 1/­2”/­150 lbs) up to DN 500/­PN16 (ANSI 20”/­150 lbs). The V-series Control Unit can also be used to supple-ment an already installed Eletta Flow Monitor such as the S- or D -series even after the installation.The Pipe Section is made from Stainless Steel and comes with BSP/­NPT threads in size 15, 20 and 25 mm (1/­2’’, 3/­4” and 1”).The Pipe Section comes in stainless steel and has the same ”fit between flanges” (wafer) execution as the -FA series and process connections from 15 mm to 500 mm (1/­2”–20”).V-GSS seriesV-FSS seriesThe V-series Flow MonitorModular designThe name Eletta has become synonymouswith flow monitoring in many industries world wide where the Products are appreciated for their sturdy and robust design.Eletta Flow Monitors are of our own proprietary design and our manufacturing as well as the whole company is certified to ISO 9001 and ISO 14000 quality standards.

Heat is removed from the sensor by forced convection due to medium flowing by. The extent of this heat transfer depends on the flow velocity of the medium and the difference in temperature between the sensor and the medium (King's Law). The higher the flow velocity or the mass flow of the medium,the greater the temperature sensor cooling.Measuring systemOverviewFlowphant T DTT31, DTT354Endress+HauserDC voltage version (DC)PNP switch output of electronics.Power supply e.g. with a power supply unit.Preferably in connection with programmable logic controllers (PLC) or for controlling a relay.A 1x PNP switch outputB 2x PNP switch outputC PNP switch output with additional analog output 4 to 20 mA(active)1Transmitter power supply unit, e.g. RNB1302Load (e.g. programmable logic controller, process control system, relay)3Display unit e.g. RIA452 or recorder e.g. Ecograph T or Minilog B (at 4 to 20 mA analog output)1 "Easy Analog RNB130" transmitter power supply unit:Primary switched-mode power supply for sensors.

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。

尤其是当回路撤离了溢流阀之后,回路中的压力过于升高,将会使液压泵损坏。

(参照图4)当压力超过检测仪最高测试压力的1.5倍时,高压油将冲垮圆盘,向外喷射油液。

(2) 液压系统试验①预备检查a、被试验机器液压油箱内的油量是否合适。

b、有没有外部泄漏的现象。

c、各部的连接是否确实可靠。

d、有没有已经损伤的零部件。

e、检测仪的5项使用要领是否都已理解。

②一般的故障及其原因通常的故障情况原因试验项目或对策输出流量减少液压泵性能下降可有以下原因:1、吸油不良(1) 吸油口有异物堵住(2) 吸油管变窄2、气穴发生3、液压泵的密封、接缝处有空气泄漏。

4、液压油内混入气体5、液压泵的损伤、磨耗、污染4) a,或 5) a发生原因2的情况,请与制造厂家商量输出力不足负载增加时速度减少1、液压泵的损伤、磨耗2、溢流阀3、控制阀4、液压缸或者液压马达4) a,或 5) a4) b,或 5) b4) c,或 5) c4) c,或 5) c负荷的保持力不足1、控制阀2、液压缸4) c,或 5) c4) c,或 5) c液压缸动作时有蠕动现象1、液压缸内混入气体2、液压缸内的气穴发生除去空气与制造厂家商量控制阀的粘咬状态1、过热、污染、锈蚀、异物、不合适的装配2、不适当的安装引起的变形3、传动机构、其他机械的不良③一般的试验条件a、检测仪的连接方法有3种基本类型(a) 液压泵试验系统系统图1(b) T型管接头试验系统系统图2(c) 串联试验(压力试验系统)系统图3b、打开检测仪的加载阀,(逆时针旋转)以防止液压机器起动时急剧的压力上升。

c、使用发动机的机器,应在发动机的暖机运转之后,调整液压泵的回转速度。

d、缓慢地关闭加载阀(顺时针旋转),使系统压力上升到工作压力。

切莫将加载阀调节到指示温度以上的位置。

因为这将使油温上升,引起内部泄漏变化使精度降低,从而得不到正确的试验结果。

④液压泵试验系统断开液压机器的回路所进行的试验下列为液压系统的活塞在无负荷时,几乎是以规定的速度运动,但当负载徐徐增加时,速度也逐渐降低的试验。

a、液压泵试验(系统图4)(a) 将检测仪的液压软管A接入到液压系统的回油腔。

这条回油路可一直持续到试验终了。

(b) 拆下液压泵的输出管路,将其接入检测仪。

(c) 打开加载阀(逆时针旋转),启动液压泵。

(d) 记录下压力为零时的流量。

缓慢关小加载阀,直至压力上升到制造厂家规定的最高压力值,并记录下与各压力值对应的流量值。

(e) 将加载阀打开(逆时针旋转),将压力降至于零,并使液压泵停止工作。

(f) 将试验结果与规定的液压泵的额定值比较,当小于额定值时,说明吸入系统或者液压泵的自身有故障;若记录值为正常值时,则说明故障不在液压泵部分。

(g) 拆下检测仪的液压软管B,将系统管路复原。

b、溢流阀试验(系统图5)(a) 拆下溢流阀和选择阀之间的管路,接入检测仪的软管B。

(b) 打开加载阀(逆时针旋转),启动液压泵。

(c) 边看压力表和流量计,边缓慢关闭(顺时针旋转)加载阀,当流量为零时的压力表上的读数即为溢流阀的设定压力。

(d) 试验的结果低于系统最高动作压力时,可调整溢流阀的设定压力。

溢流阀到达设定压力时所通过的流量必须与液压泵试验时的额定流量值相等*。

若小于该值时则说明溢流阀内部有泄漏,溢流阀需要修理或交换;若溢流阀工作正常则可将其排出故障范围。

(e) 打开加载阀(逆时针旋转),停止液压泵,拆下检测仪上的软管B,并恢复原系统回路。

(f) 根据压力表值真的振摆,压力的陡减或流量计上流量递减的开始点,即可知道液压泵输出端的平衡是由溢流阀来保持的。

* 溢流阀通常在压力上升到设定压力稍前处就开启。

在开启前瞬间的流量值若与额定流量值相差较大时,则说明溢流阀已有故障。

c、控制阀的试验(系统图6)(a) 拆下控制阀和液压缸之间的连接,并将图示控制阀出口与检测仪输入端软管B连接起来。

(b) 打开加载阀(逆时针旋转),起动液压泵。

(c) 按图示油液的流动方向转换控制阀。

与液压泵和溢流阀试验一样,徐徐关闭加载阀(顺时针旋转),并记录下各压力时的压力、流量值。

(d) 试验结果若得不到正常的压力、流量值时,说明控制阀需要修理或交换。

反之,故障的原因就可能在液压缸部位。

(e) 打开加载阀(逆时针旋转),停止液压泵,拆下检测仪的软管B,将回路复原。

d、T型接头的试验(系统图7)将T型管接头安装在液压泵和控制阀之间,T型管的中间接口与检测仪的输入端连接,检测仪的输出端与系统的回油路相接。

这种试验法是进一步查找故障部位的典型方法。

对于实际上构成全系统的一个个单元体,均可由T型管接头一一进行试验。

(a) 液压泵试验<a> 拆下控制阀和溢流阀的压力入口处,并在管路上堵上塞子。

<b> 按4) a的项目进行操作。

<c> 将控制阀和溢流阀复原至原回路。

(b) 溢流阀试验<a> 做溢流阀A的试验时,拆下控制阀的压力入口,并在管路上堵上塞子。

<b> 按4) b的项目进行操作。

<c> 将控制阀复原至原回路。

<d> 做溢流阀B C的试验时,将溢流阀A的压力入口拆下,并在管路上堵上塞子。

<a>’转换控制阀让油液流经溢流阀B,徐徐关闭加载阀,使活塞运动到行程顶端。

(另一个方法是将液压缸从回路上拆下,并在管路上堵上塞子。

)<b>’记录下无负荷时的流量,徐徐关闭加载阀,当压力上升至将要接近设定压力时记录下此时的流量。

当该流量与液压泵试验所得的流量值有差异时,说明溢流阀内部有泄漏。

<c>’关闭加载阀,直到流经检测仪的流量减到0为止。

记录下此时的压力值。

该数值即为溢流阀B的设定压力。

<d>’做溢流阀C的试验时,转换控制阀让油液流经溢流阀C,然后按上述<d>中的<a>’、<b>’、<c>’顺序操作即可。

<e>’打开加载阀(反时针旋转),停止液压泵,将系统复原至原回路。

(c) 控制阀、液压缸、液压马达试验<a> 当对具有“O”型中位机能,同时又具有数个液动机的液压系统进行试验时,只要操作控制阀,接通只需试验的某一个液动机,而其他液动机只要停留在中位机能上即可。

<b> 缓慢关闭加载阀,并同时记录下压力和流量(顺时针旋转)。

<c> 所有的控制阀均根据上述要领进行试验。

<a>’如果所有的构成统一系统的液动机动作正常,则压力和流量的数值应该和液压泵试验时相同。

<b>’如果在控制阀的某一个位置流量减少,说明控制阀的该处以及与该处相通的液动机上有泄漏。

<c>’如果在控制阀的所有位置上,流量均减少的话,则有可能是控制阀自身铸造上的缺陷所致。

此时,若不将液动机一个个卸下,顺序检查的话,将很难发现具体故障处。

请参照4)的液压泵试验项目和以下项目进行操作。

(d) 附加试验(对于(c)项中的<b>)<a> 当难以判断是控制阀故障,还是液动机故障时,可将回路上的液动机卸下,并在管路上堵上塞子。

<b> 在上述的(c)项项中的<b>的位置上接通液压油。

<c> 徐徐关闭加载阀,(顺时针旋转)记录下压力流量值。

<d> 如果原测结果与前述的(c)项中的<b>处试验数据相同,则说明故障处在控制发;如果原测结果与正常状态的液压泵试验、正常状态的控制阀试验相同,则说明故障处在液动机上。

(3) 串联试验(压力试验)(系统图8)①本试验将检测仪与液动机串联,用以调查系统实际的工作状况。

此时,检测仪的加载阀必须全部打开。

②用本试验测量流量时,油液的流动方向为液压泵控制阀检测仪液动机③本方法用以对液压系统的各个机器进行试验时,可将检测仪分别连接在液压泵、溢流阀、控制阀之后,徐徐关闭加载阀(顺时针旋转),可记录所需的压力值下的流量数值。

(4) 记录输出选择M15在工厂制作此选择档位,不管测量单位、流量和温度均用mv输出,忽略小数点。

使用此输出的记录或其他的测量仪器时,必须要有至少为5.8k欧姆的阻抗。

检测仪的保养1. 使用时注意小心、谨慎。

不要碰触或撞到硬物。

2. 经常保持清洁状态。

3. 存放时,各油口处盖上螺堵,特别要防止仪器沾上尘埃。

4. 当没有使用仪器时,要将电源开关置放在OFF位置,防止电池的无功损耗。

如果长期存放,应将电池取出存放。

电池的使用寿命是400-600小时。

5. 为确保检测仪的长期正常使用,必须注意液压系统油液清洁度。

如果对污染的系统进行检测,检测后必须对本检测仪进行清洁。
