Medir Flujo

Hola amigos, estoy haciendo un proyecto el cual consta medir el flujo de agua con Labview y una Ni DAQ, alguien tiene algun programa para poder hacer esto?
El sensor que uso lo anexo en una foto, el cable rojo es voltaje, el negro es tierra y el amarillo es señal.
Necesito poder visualizar los valores en un indicador numerico y en una grafica.

Saludos danieltuzc,
Gracias por utilizar los Foros de Discusión de National Instruments, como comenta Dennis_Knutson es necesario nos compartas un poco más de información sobre tu proyecto.
¿Cuál es el modelo de tu sensor?
¿Su salida es de voltaje, corriente, frecuencia, etc.?
¿Qué rangos de flujo deseas medir?
¿Qué precisión requieres para tu medición?
¿Qué dispositivo NI DAQ planeas utilizar?
Así bien, me tomé la libertad de realizar una búsqueda rápida basado en la imagen encontré que posiblemente se trate de un YF-S201, ¿podrías confirmarnos si este es el modelo de tu sensor? De ser así, lo más parecido que logré encontrar a un datasheet fue este documento. Te pido por favor verifiques que el modelo de tu sensor corresponda con el datasheet.
Así bien, según dicho documento la salida del sensor es una salida PWM, por lo que tendrás que medir la frecuencia del mismo para poder determinar el flujo que cruza a través del sensor, sin embargo según el documento no se trata de una relación totalmente lineal, por lo que te recomiendo utilizar una escala personalizada del tipo tabla, el documento especifica algunos valores conocidos para el sensor que podrás utilizar en tu escala personalizada.

Hallar caudal en sensor de flujo por pulsos

Buen día:
He estado trabajando en una medidor de pulsos con la Bomba YF-S201 para medir el flujo de agua que pasa por ella con arduino, esta bomba envia un pulso por cada 0,0022 litros que hayan pasado. Ahora el problema que tengo es como puedo dererminar el caudal que pasa en ella si la bomba de agua solo envia un pulso de 5 voltios en intervalos discontinuos de tiempo(segun el agua que pase y la presion).
Adjunto el VI que estoy trabajando
Agradeceria su ayuda

Buen día Juan;
Primero me gustaría mencionarle que el caudal está expresado en litros por segundo (l/s) o en metros cúbicos por segundo (m^3/s), y que ***** puede pasar del primero al segundo dividiendo entre 1000, solo como un dato extra en caso de que lo necesite. En cuanto a su pregunta, me parece que algo que podría implementar aquí es:
Primero que nada, necesita saber cuántos pulsos pasan por segundo, lo cual es medible, y luego puede sacar la cantidad de litros de cada 10 segundos, multiplicándolo por 0,0022, esto para tener un dato más certero sobre el caudal. Posteriormente, debería implementar un promediador utilizando registros de desplazamiento (shift registers); si así lo desea, en el buscador de ejemplos de LabVIEW, puede encontrar un ejemplo de cómo ***** implementa esto. Simplemente busca “average” y el ejemplo ***** llama “Running Average with Shift Registers”, con la intención de entender mejor la idea. Luego de esto, puede utilizar estos datos para sacar los litros por segundo, y de ser necesario, puede luego pasarlo a minutos o como desee.
También es mi deber mencionarle que para preguntas más específicas sobre cómo utilizar esta herramienta de LabVIEW (asumiendo que está utilizando LINX), debe postear en labviewhacker.com/forums y contactar con LVH, esto debido a que LINX no está completamente probado y verificado, razón por la cual únicamente ***** soporta en ese foro. Para más información al respecto, puede leer el “Disclaimer” de la página de descarga de la herramienta.

Medição de Distâncias usando Camera USB

Estou desenvolvendo um sistema que utiliza medição de distâncias através de análise de imagem. Essas imagens serão providas por uma camera USB. Não possuo o pacote IMAQ Vision e por isso a aquisição da imagem e tratamento dos elementos será feito "na raça". Alguém já fez isso? Conhece alguma aplicação exemplo?

Eu não conheço Portugese, este texto é traduzido pelo Internet e pode ter erros: Há um excitador disponível de http://www.cs.unc.edu/~parente/labview/index.shtml que permite a captação das imagens das câmeras do USB. Eu usei este eu mesmo criar um VI para capturar imagens para a rede. Pode ser um começo útil para você.

Med Rec medrec tutorial 10 deployments-- EJB Modules EJB is not shown

This note adds missing steps in the Med Rec (medrec) Tutorial 10
The tutorial shows how to use EJBGEN to generate EJB classes (incl java source) from .ejb files.
Unfortunately it is missing a few key details. These are described below.
Many thanks to Chris Wall for supplying the answers and hints.
Q: The tutorial includes deploying the manually generated physSessionEjb’s. After doing the step that generates the PhysSession*.java files, onefinds that when trying to deploy that there are no class files – nothing has been built. Are the class files supposed to be generated by the ejbgen step?
[Chris] No, EJBGen just generates the local and remote interfaces and descriptors only. An additional step should be added to explain how to build the newly generated EJBs. I believe you are correct in calling “src/physicianEar$ ant –f build.xml build”.
Q: Manually built the class files using ‘ant –f build.xml build’ in the physicianEar src dir – but that failed in the acc.split.dir step with class not found /org/apache/struts/action/ActionForm.
Obviously did not get the struts jars on the classpath. But as much of the build as completed did include creating the class files.
[Chris] Yes, it looks like struts.jar is not in the classpath. Is this the “build.split.dir” or “appc.split.dir” target? In either case, wlcompile and wlappc should recognized all libs in "${app-inf.dest.lib}" and append them to the compile/appc classpath automatically. The libs should have been copied during the “prepare” target. Can you make sure that struts.jar exists in c:/medrec_tutorial/build/physicianEar/APP-INF/lib? If not, re-run the target with verbose: “src/physicianEar$ ant -verbose -f build.xml build”, and make sure that the libs are copied in the “prepare” target.
Q: When doing the deploy step, we get no errors but on the console window and do not see the tutorial_deployment item under DeploymentsàEJB Modules. There is something under Deployments-->Applications --> tutorial_deployment. It appears the deploy failed since there’s nothing under Deployments --> EJB Modules, and what is there is ‘left over’ from deploying the jar (the ear?) that contains the stuff deployed by the deploy step at the start of tutorial 10.
[Chris] Once the build is successful, you must deploy the EAR. This is done by executing : “src/physicianEar$ ant -f build.xml redeploy.physician.ear”. Again, a step that was left out. Yes, you should be looking at Deployments--> Applications--> tutorial_deployment. So, to summarize: generated the local and remote and descriptors for the EJB, compile the EJB and package the EAR, deploy the EAR, and then view the deployment in the console.

14th May 2013. We placed an order on medIT (Medit Information Technology)for the following items: 6 units of Apple iMAc-All_in-one-1 core i

14th May 2013.
We placed an order on medIT (Medit Information Technology) for the following items:
6 units of Apple iMAc-All_in-one-1 core i5 2.9 GHz-RAM 8GB-HDD 1x1tb-GF GTX 660M- Gigabit LAN-WLAN : 802.11 a/b/g/n, Bluetooth 4.0-OS x 10.8 Mountain Lion- Monitor : LED 27”wide- keyboard: English.
We paid to their account; Bank of Cyprus Public Company Limited the full invoice value.
As of today 14th May 2013 we are still waiting for delivery of the goods despite numerous advices that a partial order of 3 items the order has been shipped.
We have made numerous follow up calls to medIT directly and through other customers of medIT, but we have no clue as to when we will receive the goods. On 29th April, 2013 they gave us a FEDEX airwaybill no..We regret that we have not been able to trace this airwaybill on the FEDEX system.
We are, therefore, pleading for assistance from any support group to link us with the right department so that we can have accurate information on the movement of this parcel.
These items were ordered for a government department of the Republic of Zambia and this non-delivery is creating a bad name for Apple Resellers covering Zambian market. The project upgrade of the project is now falling behind due to non-delivery on our part arising from the non-performance on the part of medIT.
We can make available for inspection copies of the order and remittance details to the appropriate office for review and ready reference.
We can be contacted directly on “James A. Ngoma”
<Personal Information Edited by Host>

If you ordered from MedIT in Cyprus, they do not appear to be an authorized Apple reseller. If they are indeed not authorized by Apple, there will be nothing Apple will be able to do to assist you in this matter. You will need to work the problem out with MedIT, obtaining legal assistance in Cyprus if necessary.
Regards.

Slow file browsing in MED-V / XP Mode with NAT and DFS

Note, for the purposes of this question, this issue is with the Windows Virtual PC / XP Mode integration portion of MED-V so is not MED-V specific.
We are in the process of deploying hundreds of MED-V instances to Windows 7 PCs to support legacy applications until they are replaced with versions that are compatible with Windows 7. Due to security concerns and our network infrastructure configuration,
we are required to use "Shared Networking (NAT)" mode for the Windows XP virtual machines. Our network drives are mapped to DFS shares. Depending on the site and drive mappings of a user, when opening or saving a file in an application,
it can take several minutes to browse to the target directory, even if it's not on a DFS share. Occasionally, it takes so long that the RemoteApp window hangs and disappears, even though the application is still running in the Windows XP VM.
Running network traces in the VM, I can see that Windows XP tries to "ping" all of the DFS targets whenever the network drives are enumerated, such as when clicking on My Computer. It waits for responses, then eventually times out.
From what I understand, this is the way that Windows XP determines which DFS target link is the fastest. Unfortunately, since vpc.exe does not run with admin rights in Windows 7, ICMP (ping sends ICMP ECHO REQUESTS) is blocked by the NAT
between the VM and the Windows 7 host. (This is why you cannot ping other PCs on the network from within the Windows XP VM when using NAT.) Therefore, the long wait times happen while XP waits for the replies that never come.
To verify that this is indeed the problem, I started vpc.exe with admin rights, then started the MED-V Workspace. I could ping other computers now from within XP and browsing took seconds instead of minutes. However, our users will not have admin
rights in Windows 7 so this is not an option for them. I also tested in bridged mode instead of Shared Networking mode with the same positive results. However, this is also not an option in our environment.
Any solutions or recommendations will be greatly appreciated.
Thank you in advance,

Old DOS program running in MED-V - WordPerfect 5.0

I'm struggling with getting an old DOS program, WordPerfect 5 to run in MED-V. I've gotten it to laund when running a workspace in Full Desktop but not in a Seamless configuration. Does anyone have any tips on getting older programs to run happily in Seamless
mode?Orange County District Attorney

I realize this is three years late, but maybe you'll see the answer. You can most definitely run MS-DOS programs in seamless mode in Windows Virtual PC, and presumably in MED-V also. You can find the method in this message on another forum:

How do i kindly reset my MED 0 so that i can unlock my curve 8520

i have have mistakenly exceeded the 10 MED options giving to me to unlock my blackberry curve 8520. and the counter is now 0 MED. i kindly want to know how i can reset the counter. thank you.

Hi and Welcome to the Community!
Please see this helpful thread to start:
http://supportforums.blackberry.com/t5/General-BlackBerry-Functions-and/Unlocking-your-BlackBerry-Gu...
If you have used up all of your chances to enter the correct unlock code, there is nothing further you can do. Even if you happen to have now the correct code, it is useless. Only the factory can now (legally) unlock your BB. Typically, I've heard that the cost of having BlackBerry do this for you will be greater than the cost of just buying a new one. But, you are able to ask them...see here:
http://us.blackberry.com/support/programs/technical/incident.jsp
Note, however, that this process will start with a fee...
If you obtained your unlock code from somewhere but it was incorrect, your recourse could be with them -- however, they may well question why you exhausted all 10 attempts before contacting them.
If your BB was already MEP locked and you obtained it from a source that represented it as being able to be unlocked, then your recourse would be with the seller you obtained it from.
Good luck!

How to set security to 'med-high'? Firefox is too broad

The broad-based settings in security are not working for me. Can't log into certain sites, rejected. Have removed cookies and reloaded pages. I long for the easier 'med-high' or 'med' setting for security and the 'clear cookies' on 'tools' This I'm sure is better, but not being accustomed, it's too broad-based.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

SAP HR to ISH Med.

I am an Sap hr consultant and i am looking to expand my skills and become ish consultant. Can anyone please let me know how to go about it...

Hi Amith,
the healthcare solution on the SAP platform consists of three parts:
SAP Patient Management
SAP Ambulatory Care Management
i.s.h.med Clinical System
i.s.h.med is developed by Siemens. However, i.s.h.med is closely integrated with the two components developed by SAP and it is delivered and installed the same way as the ERP standard software.
For getting started, I recommend having a look at the main pages of the [online documentation|http://help.sap.com/erp2005_ehp_05/helpdata/en/2e/109e377af82a17e10000009b38f842/frameset.htm] as well as at the [marketing material|http://www.medical.siemens.com/webapp/wcs/stores/servlet/CategoryDisplayq_catalogIde_-11a_categoryIde_1026616a_catTreee_1008631,1026620,1026619,1026616a_langIde_-11a_storeIde_10001.htm] on the Siemens web page. This [wiki page |http://wiki.sdn.sap.com/wiki/display/HC/Healthcare+Home] is also helpful.
There are some basic modules you definitely need to learn first, such as the Clinical Workstation (TA NWP1) which is central and the Patient maintanance (TA NV2000). Then I would recommend to specialize in a handful of modules. Being able to handle the whole healthcare solution will take some time ;-).
Have fun! Kind regards, sERPentine

Hierarchy in selection screen shows Short Text, I want to change it to Med

Hi
It seems that the selection popup of Hier is using the Short Text of the Charc.
Can I change it to use Med Text?
I tried in the Query, it only changes the way the Hier is presented in the reort
and not in the selection screen.
Thanks
Edan

Hi Edan,
You could select the type of text you want to display on selection screen by choosing the same under the Business Explorer tab of your Hierarchy infoObject.
Go to RSA1 -> infoObject -> find your hierarchy infoObject -> Display -> Business Explorer tab ->
Text type -> Medium-length text.
Hope this helps!

Windows 8.1 Support for MED-V

Hi
Can i deploy the Windows XP SP3 image as MED-v Workspace to Windows 8.1 Enterprise.
in other words, are MED-V supported to Windows 8.1 ??
Shailendra
Shailendra Dev

Microsoft Enterprise Desktop Virtualization (MED-V) is only supported on Windows 7 Professional, Ultimate, and Enterprise.
In Windows 8 and Windows 8.1 Professional and Enterprise, the virtualization engine Windows Virtual PC upon which MED-V is run is replaced by Client Hyper-V. Bear in mind, however, that support for Windows XP is ending in less than a month on April 8, 2014.
This applies to MED-V and virtual environments such as Hyper-V clients as well as physical machines. There
is a great write up on MED-V and Windows XP End of Support here which I would highly recommend reading through in addition to
the information on Windows XP EOS.

PROBLEM MED AT AFINSTALLERE CREATIVE CLOUD + APPS

Hejsa
Jeg har problemer med at afinstallere creative cloud og apps på mac.
Jeg har forsøgt at bruge afinstallere via adobe uninstall etc. Men jeg får besked om, at der er slettet noget fra Adobe på min computer.
For nylig har jeg tømt min papirkurv, så jeg har ikke mulighed for at gendanne disse Adobefiler (mindes nu heller ikke at have slettet dem).
Jeg har i stedet forsøgt at downloade cc på ny, men det kan jeg ikke, fordi jeg allerede har en version af cc - den version jeg IKKE kan afinstallere.
Jeg har forsøgt stort set alt.
Håber der er en IT-haj som kan hjælpe mig!!
