Changing flow meter's mode during the measurement

Hi,
I have the CMOSens EM1 gas flow meter which can be setted to either temperature mode or flow rate mode. However, I will need both temperature data and flow rate (in ml/min) data in order to calculate the mass flow rate in kg/min. I am very new to LabVIEW so I have no idea what I can do. What I have in mind is ... doing the measurement with the sensor in temperature mode for ~ 1 second, then change to flow mode for ~ 1 second and change back to temperature mode and so on, until we stop the measurement. So output in data file might be something like this ...
Time   Data
0       temp
1       flow
2       temp
3       flow
where temperature and flow data can be in different column. Note that the fastest sensor response time is 5 ms.
Any suggestion what I can do in LabVIEW??
Thank you so much in advance.

Hi SnowMule
Thank you for your suggestion. The data from flow meter is already in volume per minute so I only need to know density of gas at temperature T to find mass flow rate (...do I miss anything?). It's nitrogen gas and there's some online database availble to get the gas density from known temperature. That's why I want to read the temperature from the flow meter as well.
Additional thermocouple would be a solution if I cannot have LabVIEW to do the job for me.
Thanks again!

  • Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

    Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

    During sleep, your MacBook consumes a little part of the battery, so it won't harm leaving it in sleep mode. Also, you will be able to start using it quickly, as you don't need to wait until Mac OS X turns on.
    I only recommend you to turn off the MacBook if you are not going to use it for days in order to save battery, but apart from that, you don't need to turn it off

  • Changing database to noarchivelog mode during impdp

    Hi Guys,
    I am using Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production on RHEL5.
    I am in the middle on the impdp and I want my database to run on noarchivelog as it creates a lot of archivelogs.
    Will it be proper if I stop the import:
    e.g Import> STOP_JOB=IMMEDIATE
    and shutdown the database put the database on noarchivelog mode.
    then opne database and
    impdp hr/hr@mydb ATTACH=myfulljob Will these work fine?
    Or should I execute:
    alter system archive log stop;
    Please Help !!!!!!!!!!!

    Running the database in Noarchivelog mode means you should be ready to lose data incase there is any crash. I would recommend you to change the size of the redologs so that it will not create frequent archivelogs. Which does nothing about the space required for the archivelogs. If you are generating redo at the rate of 1gb/hour, you will consume archivelog dest space at the rate of 1gb/hour. Doesn't matter if those files are 10mb each or 100mb each.
    If space is the problem then use a shell script to move the archivelog to another location (Tape)....And hopefully that shell script is invoking rman to do the work, so that in the event of recovery, rman will know that backups were taken and where they are located.

    Incase you want to convert the database from archivelog to noarchivelog, follow the steps provided in the following link.

  • Will a 3 hour long download of an upgrade be cancelled if the Mac goes to sleep mode during the download process?

    I have a Mac 10.10.1
    27 in. monitor
    2009 late
    Memory 4GB 1067 MHz DDR3
    To download the above OS upgrade (10.1.1), because I noticed the long time needed to download, I clicked on system preferences, Energy saver, Computer sleep/never,
    Display sleep/15 minutes.
    The download came through in flying colors.
    My question is, did I need to do that, or could I have left the Energy Saver alone and the file would have downloaded anyway?

  • DAQ and Coriolis Flow Meter

    Hey,
    Can someone help me... I need to hook up a Coriolis Flow Meter with the Transmitter IFT9701 to the NI-DAQ - FP1000 but I can't find the wiring diagram.
    There are just three wires coming out of the transmitter (red, black and plain) and gives an output of 19.8 volts on a multimeter.
    Also, If you have any VIs or know where they are to find the flow rate measured my the flow meter, kindly send me the link or the file to [email protected]
    Thanks in advance!!
    Have a great day!

    There are just three wires coming out of the transmitter (red, black and plain)
    -- What does "plain" mean - do you mean uninsulated?
    If so, I would guess a 4-20 mA output. 
    and gives an output of 19.8 volts on a multimeter.
    That's meaningless unless you tell us if and how it's powered, and what resistor you used to measure.
    Did you look up the specs?
    It is indeed a 4-20 mA output.

    Here is a link to instruction manual for IFT9701 transmitter.  http://fmtech.kr/fmtechco/pdf/MANUAL,IFT9701%20W-LDO.pdf?PHPSESSID=fe0ca2f3d75f1164ff45858278af6554 
    This transmitter has two outputs.  A 4-20mA current loop and a pulse train.
    You mentioned that you have a Field Point model FP-1000 network module, but you didn't say which I/O modules you have.

  • Get an error for changing the windows authentication mode to the both SQL and windows authentication mode

    I installed the SQL server Express 2008 R2 and then SQL Server Management Studio 2008 R2 . But during the installation, I could not choose the both SQL and windows authentication mode and an error accrued so I did that just with windows authentication mode. 
    Now, I want to change the windows authentication mode account to the SQL authentication mode but it shows me an error which is you do not have permission (Although I am the administrator in windows), what can I do?
    Following steps are the steps that I went but I got an error:
    Server properties >> security >> choose the option of SQL Server and Windows Authentication mode 
    and the error that I got is attached(access is denied)  
    Can you please help me?

    You can change the setting after you gain admin rights to your SQL Server. You don't admin rights automatically, you have to explicitly add yourself during the install
    Here's a guide on how to (re)gain those rights:

  • How can changes happened during the cube activation  be nullified.

    Hi all,
    I was trying to activate some business content infocube in the dev.server. I selectecd data flow before. In the process I collected all infoobjects associated with the cube and all the info-objects which are associated with that info-objects. When I installed the cube some of the customised business content info-objects associated with the cube got over written by the delivered version. We dont have the documentation which provides the information on which are all the infoobjects that were modified and which were not.
    Can any one give some idea how the changes happened during the cube activation can be nullified.Or how can I find out which were the info objects which were customised before business content was again activated and which are those changes.
    Regards,
    Anand

    Hi Anand,
    As long as you did not activate the Cube (= not activate BC, but cube itself)
    you can compare the changed cube with the active cube (Change cube screen, use button Version Comparison)

  • Flow Measurement With Turbine Flow Meter Using cFP

    Hi I am trying to measure a flow rate using a Gems FT-110 Turbine Flow Rate Sensor. The cable connection has a Red one that says 5-24VDC, a Black one that says 0 VDC and a Brown one showing a square wave. If I am using a compact Fieldpoint, should I use a Counter like the NI cFP-CTR-500? How do I connect the flow meter to the module? Thank you.

    This is a sourcing sensor.  Look at Fig 3. in the manual .

  • Encore WT8 - battery discharging during the sleeping mode

    My battery is discharging during the sleeping mode.
    If I sleep the tablet with battery fully charged then battery is fully discharged after 14h.
    I suppose that must be something wrong with it. I cant find any option to activate functionality to switch off (hibernate) tablet when it is not used in sleeping mode for particular time.
    Do you have any solution or advice what I should do to change energy consumption during the sleeping mode?

    Hi
    The system supports connected stand by function which starts working after your tablet goes into sleep mode.
    Connected standby function is to provide a constant connectivity while delivering long battery life and at the same time some activities are allowed to run to ensure that the supported connected standby scenarios (for example receiving emails, updating tiles alive with fresh content, downloading/uploading a file from a/to a website and playing music) are functioning properly.
    What does this mean?
    This means that even if the tablet is set into Sleep Mode, some background processes are still running and this could be the reason why the battery discharges.

  • How to change the line item storage location during the sales order creatio

    How to change the line item storage location during the sales order creatio

    Hi Kumar,
    I think you can just delete it in the sales order directly, if you are using make-to-order scenario, then there will be special stock left for the sales order as the production has been goods receipt, you need to use MM transaction move the stock to unrestricted use stock. If you are using make-to-stock scenario, there should be no further problem. If you are using assembly order, please try to reject the sales order item to see if it could fullfill your requirement.

    Has anyone had this issue or know of a fix?
    Thanks

    Try this
    Restart iPhone: Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
    Using the phone while charging doesn't create a problem.. I do it all the time
