    Flow meter

    Hi btrueblood.... Yes, the cleaning will be a problem too. The 3D printer it's used only for the prototypes. And, as you said, there's a lot of milk meters like this one that I showed before. One of them it's from a company called Delaval, but, I suspect that the technology still the same (the...

    Hi btrueblood, thanks for the answer. You're trying to say that these patent that I showed is something like this (I posted a picture in paint brush :DD)? Thanks. http://files.engineering.com/getfile.aspx?folder=3a075175-9b04-4a1f-8b8b-ed9d6ccd6171&file=Untitled2.png

    Hi BigInch. The goal of the IR sensors it's because it's really cheap and easy to implement. And the size of the device would be really bigger if we use ultrasonic components. With IR sensors we are capable to use a algorithm called Cross correlation to compare the 2 signals of the sensors (top...

    Flow meter

    Hi dbill74, thanks for the answer. About the square pipe, yes, I already thougth about that, but our 3-D printer is incapable to print a circular pipe. I'll try to find something to implement a circular pipe. We were using a patent of a company called SCR as a reference. I'm posting the image of...

    Flow meter

    Hi bimr, thanksfor the answer. I already knew about this product of delaval. I did a research about milk meters There is a lot of milk meters that use a free flow technology. I know that's ways more difficult to implement than weigth the milk, but I think that is possible. I think that will...

    Flow meter

    I'm posting a picture with the plot of the values of the middle channel and the right channel. I don't know if my assumptions are right, but I think that something like that. http://files.engineering.com/getfile.aspx?folder=e4867301-c9bb-4029-92af-7a717bd56bf3&file=test.png

    Hi Latexman. Ok here We go. The fluid will be milk from a milking machine. The density of the milk that I founded was 1.034 g/cm^3. The dynamic viscosity is 0,00149 Pa.s . The temperature of the cow milk is about 35ºC. The milking machine uses a pump to create a negative pressure to suck the...

    Flow meter

    Hi BigInch, thanks for the answer. I'll try to increase the distance between the walls of each channel, with the goal to decrease the speed of the liquid. Do you think that if I increase the length of the channel, the liquid would be less turbulent? I had read a little bit about development flow...

    Hi evryone. My name is Lucian, I'm a Computer Engineer. I'm working in a project of a company to develop a flow meter using a microcontroller and Infrared sensors. I'm stuck in the mechanic fluid part. We're trying to develop this product basing in the mechanic model of the attached picture...
