My Slice of Nature (Part 3)
Very often, we wish to know the flow rate of our return pumps or more importantly, through the UV sterilizer. Recently I got an Apex flow sensor (1" size). Here are some thoughts that went into the piping retrofit. My AquaUV is located outside my sump but the space is quite tight. A proper method of using the flow sensor is to set it up to measure flow only when needed. These flow sensors should not be run 24/7 and in-line with the main flow. Aside from excessive wear & tear, it'll be subject to clogs (eg chaeto or vermatid snail bits getting stuck on the paddle wheel). While its nice to know the flow rate at any point in time, or to be triggered when flow slows down, the trade off far outweights the benefits. The initial plan was to set it up this way. This would be the way i'd have set it up during initial tank setup. Have a splitter and valves to direct the flow to the flow meter as necessary. Bought the piping required.... but the assembly is too large. But finally decided to go with something simpler & more versatile -just plug directly into the hose to measure as and when needed. With the threaded fittings, I could change to different fittings for different setups. Setting it up to Apex Fusion is simple. Plug the flow sesnor the the FMM module. From the task selection, select "Flow Sensor" Select the FMM module Select the port then rename it accordingly. Select the size of the flow sensor. Once done. new tiles will appear. Then drag onto the dashboard. That is is the flow rate through my UV sterilizer. 117 G/hr = 442 L/hr. WHAT!! So low flow rate!! Absolutely not maximizing the UV effectiveness at all. From here, I did some changes to the tubing and pump power to significantly improve the flow (will share more on this in the next post). Its so good to have a flow sensor handy to optimize the system and to know its possible to get up to 1817L/hr through the UV with my current plumbing & pump. Checking flow through the UV sterilizer -
