RE: GAS Usage Monitoring ?

Hi Stuart,

Have you any way of installing a pressure sensor? This will have to be
installed before the regulator though as it needs to measure the bottle
pressure and not the regulated output.

=20

As you know, the bottles often have a gauge to monitor the contents so
monitoring pressure would be the ideal way to do this. On my regulator at
home the gauge is screw in so I can install a sensor on this port. (Now you
got me thinking)

Suitable pressure sensors won't of course be cheap and probably around
=A31=
00
to =A3200 but this would allow you to know what's left in the bottle.

If you do this, you need to make sure the sensor is ideally Ex rated for

in explosive environment.

I've seen somewhere a way of doing it by measuring the temperature of the
bottle, but Google isn't giving me anything useful other than to determine
that a bottle is empty (by which time it's too late)
