Hi sir,
I'm a student of electronic eng, I need to hand in a report about explain a liquild level detector and display, I'm look for a simple circuit diagram for the report.
what I need is full circuit diagram and explaination of the circuit.
the topic is" The level of a fluid in a tank is required to be monitored. to monitor the liquid, the level is required to be display on an LED bar graph. Warning indicators are required to activate if the liquid level is below a minimum level, or if it is above a maximun level. the minimum and maxium level are to be selectable by the user, by two separate controls.
A linear transducer, for detecting liquid level, is required to be determined. this transducer will then be incorporated with electronic circuits to perform the function stated abov."
So I just want a really simple circuit to do this task, Also a explaination of the circuit.I have hand in one circuit before,
but it return back because that circuit is only indicate when the level is in that point, it can not measure the level continously! Please help me for that, Please reply me ASAP, I have in hurry to hand in this again! Thank you very much!
Regards,
Joe.
