Monitoring Oil Usage

Submitted by Guest on Sun, 08/12/2013 - 16:33

Hello to all. I have just embarked on a project to monitor my energy consumption throughout my home.

My first step is measuring my oil usage by monitoring the level over time.

I'm measuring the quantity of oil in the tank and sending that value as my input.

Is there a way I can process my feed to log a difference over time?

For example, log my total daily consumption to another feed? (start qty - end qty = total daily)

Thanks in advance!

Here is the start of my dashboard

Hello michael

Nice application! The kwh to kwh/d input processor was designed to do this, but I need to look at it again as Im not sure if its been working correctly. Its called kwh_to_kwhd2 in the input processor menu.

Thanks Trystan for the quick response. I set up the kwh to kwd input processor as the next step after logging the feed.

I added a visualization to my dashboard to test it out.

Trystan,

I don't think I am using the processor correctly.

The kwh to khwh/d is not producing the desired results. If you have the time please check out my dashboard.

I would greatly appreciate help understanding how to use the tool as you intended.

Part of my issue may be that my data is constantly reducing and I am looking for that reduction over a specific period of time to be logged on a daily basis as opposed to constantly aggregating usage over time.

I created a Google docs chart to describe what I am looking for. It is on the bottom of this page.

thanks,

michael

Hello Michael, I updated the implementation for kwh to kwhd a couple of days ago which hopefully fixes the bug with the older one, I've created a new kwh to kwhd based feed in your account it should produce the correct graph.

hmm... oil burners here in denmark have about the same flow rate.... so maybe just messure on time and multiply?

could be wrong thou

On you web site (http://ourlilfactory.com/2013/12/13/starting-to-monitor-oil-usage/) you show a picture of a red screw cap that houses the ultrasonic sensor. where did you get this cap? How does it hold up to the pressure of the oil tank when it is being filled with fuel oil.?

Thanks

That cap looks like a 3D print so I guess it was custom made to hold the sensor.
