| Sep 16, 2021 at 7:54 | comment | added | Erik Andershed | Yes I know I am asking if there is a design error or if this is common function of an water flow sensor and that is an electronics question. | |
| Sep 16, 2021 at 6:46 | comment | added | SamGibson♦ | @ErikAndershed - Hi, I watched the video, but at only 2 s long, it's too short & too "zoomed in" for me to properly see the flow of liquid around the various parts, to understand the system. Also clear liquid is hard to see. It's unclear which parts of the design are yours e.g. the rotating part? This seems to be more of a mechanical issue than an electronics one, if (as you seem to be saying) with stationary liquid the rotor is still moving - clearances too big? You seem unsure too, as you ask about whether to change the rotor case, but that's not an electronics problem, is it? Sorry. | |

| Sep 15, 2021 at 16:30 | comment | added | user1850479 | After the syringe stops applying force, how long until the water stops coming out the far end of the tube? | |

I don’t know how to be more clear in what the problem is.

Needs details or clarity | |
| Sep 15, 2021 at 8:31 | comment | added | Erik Andershed | No, sorry in this device I need a way to stop right after the flow is stopped. | |

Updated question

| Sep 15, 2021 at 1:15 | comment | added | tlfong01 | It is ok if it spins for two more seconds. | |
| Sep 14, 2021 at 19:37 | comment | added | Erik Andershed | I will update this question with more data to show the problem tomorrow. Please wait | |
| Sep 14, 2021 at 19:21 | comment | added | Pete W | It could be a "what is the transfer function of my system" question, which is arguably within EE. If you have another sensor with better response, get some steps response data, and calibrate from that. | |
| Sep 14, 2021 at 17:30 | comment | added | brhans | I’m voting to close this question because it's a software question - "How do I write a script", not an electronics question. | |
| Sep 14, 2021 at 16:54 | comment | added | Gil | The only thing that would allow the rotor to keep spinning is if it were in air or a vacuum but then only for a short time. How do you know if the rotor is still spinning. Post a schematic of your test circuit, not a frizzy picture. | |

| Sep 14, 2021 at 15:55 | comment | added | SamGibson♦ | Erik Andershed - Hi, Please can you edit your question to add more details of the sensor, a schematic for your design, details of how you are reading the sensor, and exactly where you are stuck. You ask how to write "a script" but you don't specify a language (Python? Bash shell script? Something else?). Depending on your overall design, the solution might be code in another language or even some hardware changes, rather than a script. So although an algorithm similar to debouncing a push-switch is probably applicable, it would help readers if you can add more details & context. Thanks. | |
