Arduino Prototyping Inputs #46: Measuring Water Flow

Measuring the flow of water is very difficult, unless you implement this handy flow sensor into your prototype. Although it’s not as precise as other means of measuring liquid flow, it can be very useful and can give you a good idea of how much liquid has passed through the system. 👉 Leave a tip via cryptocurrency if I've helped you out:

Would it make more sense to use a fourteen bit binary counter and save on interrupt calls? The core of this device is actually liters per pulse !!!. Therefore you would have automatic quantity measurement. Appropriate timer interrupts could give flow rate measurements if required.

[@MarcdeVinck]

Sounds like an interesting solution. I'll have to try that one day. Thanks.

bang apakah bisa lebih dari 1 sensor
jika bisa cara memisahkan hasil pembacaan seperti apa ?

I love your video sir …
Can you please tell me with the help of water flow meter and Arduino we can measure the input volume of liquid but in addition of this how we can show the tottal amount of liquid on the LCD display connected to arduino ????

[@MarcdeVinck]

If you need really accurate measurements, this flow meter isn't the right sensor. Depends also on the specific application. Measuring weight or height in a container is more accurate and easier to do. You could also use a peristaltic pump and measure rotation. That can be very accurate.

[@HiteshKumar-ci3ef]

@@MarcdeVinck actually i am making a collage project.. in which i want to show how much petrol has hone into the motorbike tank and that i will going to show by water flow meter and Arduino but how to indicate that how much total pertol is in a tank ?

[@MarcdeVinck]

​@@HiteshKumar-ci3ef Look at how a gas pump works. They dispense accurately. To measure the tank, that is very difficult IMHO, unless you use the system a gas tank currently uses (float or resistive sensors?)

[@brandonpeters1987]

Would this sensor work if I’m looking for if the water is flowing and when it stops flowing an alarm goes off

[@MarcdeVinck]

In general, yes, but without knowing the specific it's hard to say. I would not rely on it for anything critical. Water does seem to be able to pass without any signal in small quantities. If you want to detect water in general, there are other ways. You could check for conductivity in a specific pipe, or several other solutions.

[@brandonpeters1987]

@@MarcdeVinck it’s a water pump like a pond pump pumping distilled water through a cnc spindle

[@MarcdeVinck]

@@brandonpeters1987 Ah ok, so if you want the general flow amount and if it is flowing, yes, it would work. Just have it oriented vertically by the pump (I think) so that when the pump is off no water would trickle past. If you just want the presence of water, it gets more difficult since you are using distilled water and it's not conductive. There are sensors that would work. You'll need to do some searching to find one. And they get expensive!

[@brandonpeters1987]

@@MarcdeVinck what about using a flow switch ? I’ve also never used an arduino so this would be my first project.

[@MarcdeVinck]

@@brandonpeters1987 I think most flow switches are actually paddles (or impellers) like the one in the video. Arduinos are fairly easy and the community is great! You’re in good company, makes sure to check out the arduino forums too.

[@SarraHDR]

I tried the same code and it funktions undependent of if the Flow rate Sensor plugged in or not! It gives also values even when there ist no flow rate :( This code is weird

[@MarcdeVinck]

Make sure to post your question about the code on the Adafruit forums since it's their code and they have an active community. It worked for me, so maybe double check your wires, make sure your Arduino can blink an LED, etc. Eliminate any other variables.

Idonot find code please give to me the link
