how do i make a flow meter, using whatever like resistors, capacitors, and make the flow meter go like 10 second per etc help need...i am in EE 2ll basic circuit engineerin? thanks

If you wanted to do this without the electrical stuff it's even easier. However, since you are an EE major that would defeat the purpose I guess.

The easiest thing I can think of is to make a positive displacement flowmeter. That means that for every cycle of the meter's motion (piston or shaft rotating) the same amount of fluid is displaced. The only thing that changes is the speed at which it operates. From your end, the only thing you have to have is something to count frequency. You can do that with a mag pick up and notches on a shaft hooked to an o-scope.

To make a flow meter, you will need to understand the basic principles of fluid mechanics and electronic circuits. Here are a few steps that can guide you in creating a simple flow meter using resistors and capacitors:

1. Determine the type of flow meter you want to make. There are various types of flow meters such as turbine flow meters, ultrasonic flow meters, and electromagnetic flow meters. Each type has its own working principle and design.

2. Once you have decided on the type of flow meter, research the basic circuitry and components needed for that specific type. For example, a turbine flow meter would require a rotor, magnets, and a Hall effect sensor.

3. Create a schematic diagram of your flow meter circuit. This will help you visualize the components and their connections.

4. Choose the appropriate resistors and capacitors for your circuit. The values of these components will depend on the type of flow meter and the desired flow rate range.

5. Assemble the circuit on a breadboard or a PCB. Make sure to follow the schematic diagram and double-check all connections.

6. Test your flow meter by connecting it to a power source and a flow source. You can use a pump or a water faucet for this purpose.

7. Calibrate your flow meter by adjusting the values of resistors and capacitors to match the flow rate readings with the actual flow rate.

8. Once you have successfully calibrated your flow meter, you can make it go for 10 seconds per unit of measurement by using a timer circuit or a microcontroller.

Overall, building a flow meter requires a good understanding of electronic circuits and fluid mechanics. It is recommended to consult with an experienced engineer or conduct further research before attempting to create a flow meter on your own. Good luck with your project!
