water level inspection system

I want to put in place a water level control system, but I want to produce a material too...

Anybodys, who got this kind of experiences, please share with me...

I appreciate all your guidelines. Looking forward to your answer with impatience.

Thank you very much.

Very simple: use a toilet tank level control and add a potentiometer, ok, use the potentiometer (it is advisable to use a more protected ;-) and replace the button with a peace of aluminum with an old tennisball at the end use (10kOhm) potentiometer as a voltage divider (a leg (CW) forever, CCW to Vcc (5V) and tap to Analog in))

If the water level is regularly down, take a look how to use devices of modern laundry: they use a pressure with a pipe of air filled sensor.

A fit to be dropped in the water absolutely pressure sensor is lovely.

However: The water and electricity don't mix well, so take care what you do. If humans can touch the water, all devices must meet strict isolation class. Normally a PC card entries are not them!

  • Control valve tank with plots and twists of the water

    Hello everyone!

    This is my frist real project. And I am in love with this program so far!
    I have a little problem. Here it goes:

    The project of the University which has been given to us is to simulate a (entrance OPEN/CLOSED valve) water tank filling and emptying (output range of 0 to 100% valve), but with a few twists. It is done by the command to the movement by the following formula: flow rate [%] = position of the valve [%] * current water height [%]. (The output valve takes values in percentage from 0 to 100% giving the voltage digital output of 0 volt to closed(0%) or 5 volumes for open(100%), the strange part, is that the digital output can have a value of 0 or 1, so the position of the valve is "simulated".) And the supply valve (valve entrance) water can be open or closed (if 0 or 5 volts)

    -Sequences cannot be used (only one for initialization and cleanup can be used)

    -When the water level reaches 10% of the max height, LED lights, the output valve closes and the input valve opens. The LED is on until the button is pressed. The output valve cannot be opened until the water height is greater than 50%.

    -When the water level reaches 90% of the max height, LED lights, the entrance valve opens. The LED is on until the button is pressed. The output valve cannot be opened until water height is less than 50%.

    -There are two mode selectios:

    Control by hand: the person sets the position of the valve in percent and the flow is calculated by the formula and displays on the screen.

    Automated: Every 2 seconds the program assigns the place valve so that the current is constant, it is the value by the person.

    -(N'ont pas gottern ici encore) ESD (Emergency shutdown switch) the when is pressed both the entry and exit valves are closed. The entrance valve cannot be oppened up to the RESET_IN key. If the program is 'Control in manual mode' output valve cannot be opened until the RESET_OUT touches. In which case the output valve is in "Auto" mode, it does not start work until the RESET_OUT touches.

    My main problem here is the fact, I cannot use sequences and nested, then the loops do not work. The aqusition of data stops until the inner circle loop ends and I need both work. Especially for the 50% rule.

    I've been hitting my head for a few days and still couldn't come up with a solution.

    I have attached the VI.

    Tips are welcome!

    For the time being the outputs inputs/digital analogue are a simulation (when the time comes the USB-6008 material is used).

    There is some things that confuse me (as if the valves are percentage, from 0 to 100%, or digital, 0 or 1), but regardless, it's a detail.

    Review the task and consider what you want to do and that the "States" the system may be in.  [This with a pencil and paper, do not open LabVIEW yet...].  The description of your problem learn you something about the transition from one State to another.  Here is a thought exercise:

    Suppose you are in a "State".  Let the system to "do its thing" for a second, which could involve the water flow.  At the end of the second re - evaluate your state - it changed?  Continue to do this...

    This model of 'something' is called a State Machine and LabVIEW has some very good examples and tutorials on the creation and use.  The important things to do before you make your coding is (with the pencil and paper) decide on your statements, decide on the transition rules, and then you are ready to code.

    There are different ways to build a State Machine in LabVIEW, but the basic idea is quite awhile (to keep things moving along, a shift register which includes the current state, usually represented as an enumerated, Type whose values are simply the names of your States (made for a very mnemonic routine) and a Case statement whose power is the State of the shift register that contains the code to achieve this) particular State of loop, including the implementation of transitional rules (which can cause a new State on the registry to lag when it comes out of the investigation of the case).

    A great exercise.  Strive to keep your block diagram on a single computer screen by making use of the screw subgroup chore (as the management of changes in the water level based on the current water level and "States" (which here means 'values') two valves).  Once you understand the 'Idea' State Machine, you should be able to write the code for this problem quite easily.

  • Tank system, custom front

    I had a tank system, instead of having all the settings for the system in the front panel. For example, to adjust the water level, stop, etc. It is possible get these control and indicators for the water system tank is displayed in another window by pressing the front wall tank?

    If you are familiar with the concept of a Subvi, you can do a Subvi act as a popup to play with the properties of VI. You can trigger this popup in your code using a mouse event down or something similar. Usually, when I have configuration settings, I hide them under a separate tab on the front panel. I like tab controls well, and not some people.

    This feedback node to store the previous level.  From there, just subtract the new and the old and use the sign function.  This will give you an - 1 (descending), 0 (stable) or a 1 (increase).  Just use a case to interpret this structure in your Boolean flags.

  • How reset Mixer volume levels?

    This should be easy.
    I have several applications launch and tweaked their levels of volume in the volume mixer, so now, several applications have slightly lower volume than others.

    How to reset all easily to match the volume level of system?

    Hello

    Please follow below the steps mentioned and look for the question.

    1. Click Start, click Control Panel, and then double-click sounds.

    2. in the sound dialog box, click the Read tab, click the speaker device and then click Properties.

    3. click on the Advanced tab, click to disable the applications to allow him to take exclusive control of this devices check box, and then click OK.

    In addition, open the volume mixer and adjust the level of the volume of applications to ensure that the volume on the unit.

    If you are still not able to do so, you probably have reset the settings of the volume by reinstalling the audio drivers to match the volume of demand for the volume on the unit.

  • Traffic generated by router IOS inspect IPv6

    I try to configure the IPv6 packets on a router 2911 deep inspection (IOS 15.1 (2) T5) but I'm not able to inspect the traffic generated by router. It is not an option "ipv6 inspect name xxxx udp router-traffic' as in IPv4. So I am unable to ping to the router to a remote host.

    I could solve the problem of ping by simply adding a "permit any any icmp echo response" on my ACL, but I still can't access TCP or UDP based services (DNS, HTTP,...).

    Anyone knows if it is possible to activate the traffic generated by IPv6 router, or is there another solution for this problem? If so, how can I do that?

    Partial configuration:

    ipv6 unicast-routing
    
    ipv6 inspect name SPI_DIALER1_OUT tcpipv6 inspect name SPI_DIALER1_OUT udpipv6 inspect name SPI_DIALER1_OUT icmpipv6 inspect name SPI_DIALER1_OUT ftp

    Former Cisco's IOS 'inspect' system has indeed been deprecated.  You should use zone based firewall now.

    Here is the guide for the care of the IPv6 zone based firewall.
