How can I count time ?

Hello Flukso.
I don't own a Flukso yet but I have one question to ask.

I need to measure one input (central heating) by counting the time the heater's electrical circuit stays on. I could do this by monitoring the analog measurement but I don't want to waste one analog input for that.

Flukso has two pulse inputs but I need one of them to count time instead of pulses. Then I need to map time to fuel units (liters of oil) and plot the result.

How can I accomplish this?

Thank you.

@fluppie007 I'm not able to reproduce the 'gap' issue. Could you change the FLM's config so that it starts misbehaving again? Then leave it running in that state and report back so that I can do some debugging.

Just change the meter constant to: 1512.163 for gas/oil and put a 1Hz pulse generator on the input. You can also look at my graphs before 05/11/2012 18h00.

Ok. I was assuming that you set the meter constant to 0.00151. But you set it to 1512.163 instead. This makes much more sense. The blanks you noticed in the chart are due to some sanity checking before committing meter values to the database.

I still suggest you set the meter constant to 1.512.

Changed it!
