[I thought I saw a FGA used in the 70`s - liquids changing colour when exposed to a drop of sniffed gas --- OR am I thinking of a concert I went to
This would be a 'Fyrite' kit, using absorption solutions to measure CO2 and CO. Along with a smoke pump and a thermometer, it will do exactly what a FGA does today. It is still allowed as a viable option to satisfy the OFTEC analysis requirement.[/quote]
My God ... just had a relapse back to my apprenticeship ... cold sweats and fear have struck me .... that big angry fitter screaming at me .... think I need some therapy .. had blocked it all out till you mentioned the word Fyrite .. Crying now ...just had to type the word
Cmon chaps lighten up a bit .. still see the old boy that I did my time with and still feel that hes forgotten more than I will ever know and this year is my 30th as an engineer ... Most of us that work on oil regulary have a feel for it but Im sure we all use a FGA
Me .. I do smoke test, new nozzle, reset pump pressure and the FGA is normally spot on and of course we clean out the boiler etc etc
Oil service we charge 100+vat for ones we have fitted .. if its our first visit for boiler we have not fitted 120+vat ... and yes we are busy
