If broken biker don't want one is the offer open to me ? I have a half size cylinder which needs an online one to function as the pea shooters i have don't fit. If it is let me know your PayPal and I will send you some beer vouchers..?What range of flow do you need ? We've got a few very accurate rotameters at work just sitting around. I'm happy to post one out to you if you want
It won't fit direct onto a reg but can be plumbed inline quite simply
