We are selling our beer flow meter we purchased just a year and a half ago. This device has been absolutely amazing for us as we have been able to move this flow meter around onto any transfer pipe and measure liquid in gallons. We are able to measure mater going onto the mash, mash sugars going into the kettle, wort then going into the fermenter. Then measuring final product going into packaging. Allowing us to see liquid loss from start to finish. This comes with a plug and play system so you do not have to hardwire this into the electrical. Below are the details from the company. Gently used for a year. It is in perfect condition like new.
