flow meter for measuring water volume

[RuairiH98]

Hi all,

I am a student currently working on designing a flow meter to measure the overall water flow through a tank over a space of time, not neccessarily the flow rate or the flow of liquid per second as it wont be a consistent flow. I am not great with labview and would appreciate it greatly if anyone could help me out with starting the program and how I would be best to go about it. Screenshots of ready made labview programs for a flow meter would be useful also if anyone has experience in such a program.

Any help very much appreciated,

Thanks.

What flow meter are you using?

What is the output?

What have you tried?

Post the code you have so far.

We are not going to write your code for you. There are many resources for you to learn how to use LabVIEW. They are located at the top to middle of the forum page.

Without knowing any of the details of the hardware you will be using to actually measure the flow all anyone can do is give you a vague outline of what such a program might do.

1. Configure instruments, setup or clear indicators, zero total flow...
2. Check for flow
3. If there is flow then measure it
   
   1. Add measurement to total flow
4. Goto 2

Hi all,

This is my program I have managed so far,  My attempt at measuring the flow and conversion from the pulses to litres hasn't been a success. My sensor is a Sea Water Flow Sensor, Model: YF-S201, it counts pulses of 450 pulses per 1 litre but I have been unable to achieve this conversation as it will need to display in litres on my graph.

Any help is greatly appreciated

Why not attach the actual VIs?  I cannot read pictures of screens.

But since you are trying to count pulses, why not use a counter?  Then it is a simple division by 450 to get Liters.  What DAQ are you using?
