Hi. I am looking for a digitally controlled valve (12V preferably) to open/close the fuel flow on a 1"-2" pipe. I know they exist but don't know what they are called. Can you help with a name and/or suggest a manufacturer?
Thanks
Hi Mike. Capacitive fuel sensors are linear with the height of the tank. It is up to you to do the math to find the volume for a given level of liquid (and I am OK with that).
My concern is as I mentioned the sloshing of fuel in the tank as the vehicle moves and getting a good reading. I...
Thanks Mike. Well, the idea to measure while stopping was, well, just an idea.
From what I have read so far, and I am still Googling, of course averaging is the way to go. But what type of average... there are many.
By the way, a related issue is that, the idea is not to provide data logging...
I plan to use a capacitive fuel probe to detect the level of fuel in commercial vehicles. The principal is simple, the probe provides a frequency (or voltage) that is proportionate to the level of fuel. Doing the math based on tank geometry is also OK.
But what I am wondering about is hot to...
I would like to design a circuit that will generate a square wave of zero to 500Hz (preferably with 50% duty cycle). Should be adjustable by single potentiometer. Any suggestions? Thanks.
Hi ScottyUK. OK, sorry. I am using a LM2575-5 for the 5v and the sensor does not require much current (I don't know how much, but not much, it is a Hall Effect device). So regardless of budget for a moment, do you advocate adding another regulator? Or would you be comfortable using the same 5v...
I have a board that has a 5v rail for microcontroller (and other electronics). I also have an external sensor that I need to provide 5v to. I am concerned, that if I connect the 5v from main rails directly to the sensor, the entire board will go (in case of fault/short). Previously I have...
