Hey Dave! Phil Kelm formerly from Atlanta Brewing. Remember? Anyway, yes I am using flowmeters for monitoring flow from bright tanks. I'm in Seoul now and the government requires flowmeters to base taxes on. Check out the sanitary turbine flow meters at http://www.sprintent.com/productsSentrySystem.html
There are a few design flaws such as: the turbine unit has exposed circuit board on the back of the unit that makes it difficult to install in a washdown area such as a cold room. There is also no provision for interrupt, so it also monitors flow of your line cleaning/sanitizing chemicals. But it does work. We have two in tandem for eight lines. I believe you can buy this through MicroMatic. Good luck!
