RE: Domestic Gas Flow Monitoring

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

Depending on the age of the meter it may already have the facility for an
optical reader that will give you the pulsed output, otherwise you are
looking at a secondary meter with the facility built in. Likewise for water
except that they usually have the facility for a reed switch to be fitted
rather than the optical reader.There are also ultrasonic flow measuring
devices available that do not require the meter but I've never found them
to
be that accurate.

After that you'll need a suitable monitoring & targeting application or
need
to knock up a bit of code to capture the data. As usual, off-the-shelf
packages are available but at very high cost unfortunately.

Subject: [ukha_d] Domestic Gas Flow Monitoring



I am looking at monitoring the energy consumption of my home and need to
find a device for the gas supply that can be interfaced electronically
somehow. Ideally I would like a nice low cost flow device that could be
installed inline with my incoming gas feed and provide pulses out rather
like the electricty metering does based on volume of gas used / flow rate.
Looking for some feedback of both consumption to date and instantaneous.
Cumulatively counting pulses is not a problem to estimate consumpton to
date
if needed.

Does anyone know of such a device ? I am sure there must be many of them as
there are in the electricty consumption field. Probably used by landlords
for secondary metering but the 'pulse' output is key - not just visible
dials.

A water one would be nice too...
