=============================
We were glad to visit with many RealPars fans at HANNOVER MESSE in Hannover, Germany, back in April, but if you didn’t get a chance to be there, here’s one of the demonstrations we had running at the Endress+Hauser Group booth.
In this video, RealPars Business Developer and PLC guru, Shahpour Shapournia, walks you through a demo of a practical application of level sensors, pressure sensors, and RTDs.
You’ll see two tanks, B-1 and B-2, both filled with liquid and outfitted top and bottom with the flow, level, and temperature sensors.
Watch how liquid levels, tank pressure, and temperature can easily be measured with each setup, and how each one is able to send critical level, temperature, and pressure information back to the PLC so it can do its thing, whether that adds more liquid, adjust the temps or shut the whole tank down. Brilliant.

I appreciate your efforts team Realpars . I learned so many new things because of your youtube channel . Thank you very much and keep up the good work guys.
That's a great compliment, Nilesh! Thanks for your support. Keep up the learning curve! Happy learning!
Since the free membership is going to an end (sadly), I should've kept taking your courses from your website. Great content you guys have! Thanks!
We appreciate your support! Glad to hear that you will still be part of our RealPars family.
Happy learning!
Looking forward to more practical demonstrations such as these! Would really appreciate some further insight into instrumentation calibration and commissioning
Great to hear! Thanks for your support.
Next time show us the plc as state the weather they analogue / digital inputs . Thanks for sharing 👐✋
Great video!! And with the best instruments of the market, E+H ;)
Thank you, Renan!
You are great .Thank you very much for all !
You are very welcome!
good work. looking forward for more these type of videos
Great to hear that! Thank you!
Thanks for show it to us!!
You are very welcome, Jorge!
Thank you very much :))
Ahmed from egypt
You are very welcome, Ahmed!
Thank you for good explanation !
You are very welcome, Vladislav!
thanks for this video..
very very insightful
can u pls write a program for level transmitter ( i need to know if analog signals/devices can be latched)
Comparator Function Blocks can mimic latching behavior for analog signals. So yes it possible to latch/unlatch analog devices.
If you are trying to latch an analog signal based on a particular threshhold being reached, then use a comparator in conjunction with a move instruction. Analog signals are received at the PLC in counts, and this value is usually scaled to give the analog input in engineering units. If you take the raw counts and then compare it against a threshhold value, you can selectively move the counts value to scaling logic, which would store the result in a REAL variable. If the threshhold is exceeded, then do not pass the value to the scaling block. The scaled value will then remain unchanged, or latched. Realpars has several videos on analog inputs and outputs. Check them out at Realpars.com!
Thanks....... Mr. Realpars I am requesting you to make a video about how wiring analog signals like (RTD /PRESSURE /LEVEL) Sensors like a digital wiring and thank again
You are very welcome! Have you watched this video? th-cam.com/video/qeBAz_XXUWs/w-d-xo.html
It's really helpful. Thanks mahn.
Thanks for your support!
Thanks for the value information
You are very welcome, Sai!
Very informative!
Thank you!
Thanks for the Video.
Wired Transmission or Wireless / Wifi Transmission? Range? Type of Processor , Programming Language.
In this video, the level and pressure transmitters were 4-20 ma devices. The switches were 24 VDC devices. The PLC was likely a Siemens 1200-series PLC using ladder logic. Sensors can be purchased which are wireless,. and these would use either wireless HART or ISA 100 wireless as the communication standard. Use of wireless instruments will require the use of a wireless gateway. PLC programming can be accomplished most easily for this application using ladder logic, function blocks, or structured text.
Thank you
Best channel
Great to hear that, Aqeel! Thanks a lot!
Nice stuff thank you
Thanks for your support! Happy learning!
I appreciate your efforts Realpars.
Please sir can you recommend text books for me to learn more on PLCs, Thank you.
Hello Danielstephen,
Thank you for your question! Depending on the manufacturing platform you would like to learn, you can go to the manufacturing website like Siemens, Omron, and Allen Bradley, for example, and get free books from them in PDF form. In addition, we at RealPars have free training on Siemens PLC, but you must register first for free. And if you like to take it a step further, you can purchase the affordable PRO membership. A great investment in your career as a PLC programmer or technician. Below are some links for your review. Happy learning!

@@realpars Thank you so much for the reply. I love the Realpars team,
And have really learnt a lot from you. Wish you more success.

Hello Shahpour,
Thanks for making the very informative video. You appear to be at a conference/convention. I and others at my work would like to attend such a conference/convention. Please share the name and location of the conference/convention you are attending in the video.
Thanks
Ron
Hi Ron,
Thanks for your support!
Sure, the name is 'Hannovermesse', and it's in Hannover, Germany!
Happy learning
Awesome ..... and Thanks ......
You are welcome!
I love to see your videos... 🙂🙂
Glad to hear that, Rohit!
What is the type of sensor that is shown as a black box type labbeled Durker? at 4.37 which looks to me like a flow meter
The "black boxes" you are referring to are Burkert 2-way flow valves (solenoid-driven). They shut off the flow in the de-energized position and allow flow in the energized position. Just to the left of the Burkert valve in the foreground is an E+H ProMass straight-line coriolis flow meter.
@@realpars Thanks sir!
Thanks for your videos. Please can you upload the subtitle
Hi Bitebo,
Thanks for your comment!
We currently only have auto-generated subtitles for this video.
Sorry about that!
