RE: Domestic Gas Flow Monitoring

["Kevin Hawkins" <lists@xxxxxxxxxxxxxxxxx>]

Its the actual hardware (secondary) metering I need - I don=92t believe my
=
Gas
meter has such an inbuilt feature as it's so old. Maybe when updated it
wil=
l
have. The software & interface is no problem (he said optimistically).

So I need a pointer to a low cost sensor device - I don=92t even need any
dials or digital readouts - just a pulsed output. Currently I have found
some gas meters at =A3105/=A3210 depending on flow volume and water at
=A37=
0-=A3120
pulse only. Electricity is much lower cost at =A340 ish.

The Gas solution still has dials like my existing meter so I am convinced
there must be a lower cost (without readout) device available. If not I am
pleasantly surprised by these costs anyway so it looks a go-er
