Propane gas metering with Flukso

I installed a propane closed fireplace gas burner.
Closed means ==> all burned gas,... are directly removed through a chimrey.
I should like to measure my propane gas consumption.
Is there any device/sensor available working with the Flukso setup?
Again => it is a propane gas installation. Most of the installations use natural gas metering.
Flukso has a few sensors available for this type of device.
