The only thing I would add is a load cell depending on the application. 1- The Pump does not really know if flow has started or not. So there no way to know the qty/volume of liquid displaced. By measuring the weight before and after one can make adjustment even suck back any excess if needs be. 2- Depending on the liquid viscosity the flow rate might be different so again adding a load cell and weight in before and after coupled with PID one can reach nice precision and repeatability.. Good job.
In addition to pualingho's comment. Usually, devices with a peristaltic pump work under the assumption that the hose is already primed (you only have to manually prime it until the supplied liquid runs out), thus making the length of the hose irrelevant to the computation of the volume.
You may try to measure the water by electronics balance, 1ml of water equal to 1 gram. By providing the feedbacks to the pump, you will have a more accurate result. I did the same thing to the hospital infusion pump, and they work perfectly.
Excelent job, I am making a similar one, but taking advantage of the fact that it is a stepper motor, I intend to calibrate it by turns instead of by time.
Peristalitic pumps do have a fairly precise flow delivery. You must use a high quality silicone tubing in the pump body and have the walls close on the fluid flow but only just to avoid damage and motor strain.
This is great, but your measurement is slightly off, the bottom of the meniscus is the point of measure, your 50 is actually 49. Truly nice function, recalibration shouldn't be too difficult, another 120 degrees would've likely got you right there, it's simply when the fluid stops, there isn't enough liquid pressure to get right on the mark.
Time is supposed to start when all air move out of the pipes in order to have a correct quantity dispensed. In my machines I have the pipes always full of liquid, since they are dedicated for the same liquid always.
Do you have your pump always lower than the fluid heights? I'm looking at dosing 10ml of fluid and feel if I have the pump higher than the level of detergent then there will be a small amount of draining out of both the hoses until a small vaccum is present. So the dosing will not be accurate when aiming for a 10ml dose only... Or will that level drop be consistent so I can calibrate it out? The pump and tube diameter I'm buying says its only about 10mL per minute so I'm hoping to get some accuracy out of it.. Never used a pump like this before and waiting on it to arrive.
Good one...thank you...I would have taken it to next level to have the data input on the phone with wifi link to the pump... or even Bluetooth. But on the whole good project and like you have used one way valves...
i like on 1:23 where he uses jigsaw to cut the shape around the plywood and then using mini table saw, just cut with jigsaw the shape and dont need to cut it bigger by 2 centimeters :D
oh i see now.. not only that is susceptible to temperature but is also very noisy. You cannot burry it in the ground because it has no pressure so this is useless. I was thinking its a clever pomp but no its not.:D
Meh. I rather use small dc pump. It's faster and if angled right does not need to be primed by sucking out the air like you did off camera with your video edit because all action starts with cup already partly filled.
I think you misunderstood the purpose of peristaltic pump this pumps are different from other ones peristaltic pump is used to transfer fluid without contaminating it high flow rate is not the main aim. peristaltic pump does not required priming they also known as dosing pumps.

Good job.
peristaltic pumps should move same ammount of liquid no matter the viscosity. it depends on tube inner diameter, not on liquid.
In addition to pualingho's comment. Usually, devices with a peristaltic pump work under the assumption that the hose is already primed (you only have to manually prime it until the supplied liquid runs out), thus making the length of the hose irrelevant to the computation of the volume.
@paulingho and @PiTy thanks

do we require separate driver or just we can connect stepper motor directly to Adrunio??? Thanks in advance
What I think would have been a great addition is if you could show a reliable flow rate, like 100 mL in 30 min for example. But anyway, great work!
Peristalitic pumps do have a fairly precise flow delivery. You must use a high quality silicone tubing in the pump body and have the walls close on the fluid flow but only just to avoid damage and motor strain.
Why don't you show yours with 100ml flow rate? Show him how do things!!

Nice job you should fine tune your pololu driver, seems like stepper driver is overloaded.
This looks great, i need this part for my master ❤❤
My arm hurt looking at it. Still remember the morphine IV that didn't do squat for me. I did have plenty of time to look at that pump though.

this is cool! does it work both ways?
If you want to optimise it I may have some points that you could check
Awesome project. I want to replicate this for a project at home. Are you planning on uploading the board's schematics and/or Gerber files?
Can you make a tutorial for a filling machine using a pump and flow sensor?
How long did this take you to make? Asking cause i am making a similar project at school
Hello, what are the measurements of the silicone tube, both exterior and interior?
Good one...thank you...I would have taken it to next level to have the data input on the phone with wifi link to the pump... or even Bluetooth. But on the whole good project and like you have used one way valves...
Hi friend i need plexy glass and slicon tube dimensions. Can u give information about this
Can you share the code how to make tft to accept input? And inturn read the code and control the pump
i like on 1:23 where he uses jigsaw to cut the shape around the plywood and then using mini table saw, just cut with jigsaw the shape and dont need to cut it bigger by 2 centimeters :D
youtube is bent restricting the flow. cool project. pun intended
why do you need 2 water check valve instead of 1?
Great prototype, thank you!
How many bars of pressure does the pump have?
What is the OD and ID of the tubing you are using ?
que capacidad tiene esta bomba para controlar ph de una piscina de 25 m3 es muy interesante
sir it is a successful design
Hello, I have an idea, you could create a system that wraps every 5 or 10 coins with tape
hello, I would like to buy the schematic of the board to have it made
Is there have enough pressure to push syringe
oh i see now.. not only that is susceptible to temperature but is also very noisy. You cannot burry it in the ground because it has no pressure so this is useless. I was thinking its a clever pomp but no its not.:D
Hallo. Wo finde ich diese adapter für den silikonschlauch?
Best idea . thankyou.
amazing tool mate.try to make it silent.may I order one?
Great job!!! What 3D printer did you use?
He uses Samsung Galaxy S10 turbo 4 NX23 printer
Vary nice brother keep it up
Want learning how to control or code this lcd and how it working
Can it give an accuracy of 0.01 ml?
Well done Sir. 👌🏻
كم لدي من افكار مثلك و لكن ليس لدي القدرة على العمل بسبب عدم توفر المواد و المال لهكذا عمل 😓
very interesting video
why you need CNC shield?
can you post touchscreen code used in adruino
Kreatif banget 😀
Good job
Please can you make video how code this lcd
Why two motor drivers?
Amazing great job
Nice video
Please provide source for tubing and connections on tubing.
No
i'd like to make this :D
How do u reduce the pump humming noise😊
Any controller with microstepping should do the job. Like drv with 1/32 steps on TMC with silent step even better.
Hey bro can you suggest me any good topic for my ece mini project it should have a noval idea pls 🙏
👍👍👍
Why we need this pump All work suction tranfer of water what is different
Like mama said; *USE YOUR WORDS* _that would be so much better than porn music!_
What kind of tube are used?
Most likely silicone ones
I need this
1 000 000$ Man!
Brutal 👌 👏 👏👏👏
great 👍 but not durable
😝 Promo sm

@@MrInnovative Except you DID contaminate it by priming it with your mouth

Hi
Probably your local hardware store has aluminium profiles and tubes
