I have dual tanks and want a visual gauge to determine how much propane is in the tanks. I would like an inline gauge that can check both tanks What do you recommend??
those separate gauges, are sold at Costco and are famous for their inaccuracies. and the hot water trick will give you an exact amount. the best these gauges can do, is ballpark it, if they don't act up.
i have one and only use it on my bbq grill's tank.
