What I can't understand is why that tower costs as much as it does: a couple of valves, a flowmeter and a stand.

Its really the only thing holding me back from getting the whole system. If the price for the tower came down 150-200 I would probably already own one

I just picked up a rmc-142-ssv this week and will be giving it a run this weekend. 0.2-2.0 gpm should give me a god range for recirc during rims & sparge. It says max temp is 130*, but that's at 100psi. It's polycarbonate and stainless so I'm not really worried about leaching or anything else.

Default My Blichmann Substitute

I ran a wet test with this setup yesterday and added the new flow meter in on the left. So far so good, although the test was only with water.

By having the flow meter before the RIMS tube and part of the MLT wort out, I can attempt to dial in the sparge and recirc rates. Right now sometimes I sparge in 20 minutes, and other times 40 minutes or more. It will be nice to know how fast I'm really running.

Search for Polysulfone Flowmeter and you should be able to find some sources. Coleparmer has them for about $100.

I have been reverse engineering the Blichmann and pretty much have it complete. The cost they are charging is not excessive. I think they have a resonable markup based on the cost I came up with to build my own. I'm pretty sure they are using a Fenwal 120 volt spark igniter. If someone ownes one, can they confirm this.

the controller or the tower part with the valves and flow meter? i would not guess that the controller is cheap, it's the tower part that seems expensive to me.

True, the markup on the tower stand is higher, but there are a lot more pieces. The flowmeter and some of the stainless fittings are pretty expensive. You could make an almost identical one for a lot cheaper. Definetly worth trying.

I bought two controllers, but skipped buying the tower based on cost and my desire to have something that was attached to my stand. For $35, I bought a CRT TV mount, used the Blichmann plate for two controllers and mounted everything to the brew stand. It articulates. So I can move it around when I'm working with hoses near the HLT. I use a pyrex measuring cup to measure my flow. Works well, but lacks the auto shutoff feature. I monitor my flow for the first 10 minutes or so. After that, there's not a lot of chance that things are going to get stuck.

dcbc, where is the measuring cup/flowmeter in this picture and how is it working for you? I'd like a less expensive alternative to the ToP tower myself.

Thanks,

MikeB

after brewing 4-5 batches using the TOP i can see the value of a flowmeter. the recirculation stopped a couple of times and the mash got up into the low 190's before i noticed it, bummer but i still can't see paying $500 for the TOP flowmeter stand.
