Toro Flow Gauge

[soafone]

I have a one inch water main in a residential home, going into a 5/8 water meter, then back out to one inch pex pipe. Right after that, if I were to install a 1/2" boiler drain (aka. sediment tap) off of the pex pipe, and I was to attach a Toro flow gauge, how accurate with the gpm reading be? Would the reading be an excellent figure to base my zones on as far as flow (gpm's) is concerned? How many gpm's could I expect it to be? I have attached a pressure gauge at the hose bib at the back of the home and it reads 55 psi.

I suspect that the Toro flow gauge would not accurately measure the gpm's since I am connecting to a 1/2" boiler drain, not directly to the one inch pipe. The hole inside it the boiler drain is pretty small and very restrictive of volume. What do you think?

Yeah, not very accurate. I never thought much of those Toro flow gauges either, we used them back in the early 80's.

It is a vague generality, that in a home with a basement water meter, the flow and pressure you read at a hose bib located not too far from the meter, will be what the system will have available, on account of the losses in the pathway through the hose bib being more or less what will be lost through a PVB and an electric valve.

You will likely exceed the 15gpm the gauge reads if you installed at that location.

Through a hose bib? 15 gpm? Not likely.

No, right after the meter is what he said...

I agree, I thought I was becoming a real "tech" when I bought one, until I noticed the warning that said "do not exceed 30 pounds pressure."

that's because the flow gauge is really a 30 psi pressure gauge with a special scale that's keyed to the size of the outlet

I think that Toro gauge banged around the service truck for a couple of years until I chucked it. We'd already bought a couple of these, which worked swell.

If you dont exceed it's ratings the gauge is accurate according to a bucket test.

Now these are very accurate. I have one and have used it many times.
