A Flowmeter measures the actual flow of water through your recirculation system. These meters are calibrated to the size of your piping - e.g. if you have 1 1/2 pipng you would purchace a 1 1/2 inch Flowmeter; for 2" piping, a 2 inch Flowmeter etc. This 1 1/2" Flowmeter will measure between 20-75 Gallons Per Minute (GPM). This guide shows you how to install a Flowmeter on the discharge side of a 1 1/2" pipe system.
CHECK YOUR PARTS - For a 1 1/2" pipe, we will be installing the 1 1/2" Flowmeter, F30150P. The F300 series mounts on horizontal pipes. The D300 and U300 series mount on verticals pipes. Other parts include: 2 stainless steel clamps, a gasket and two screws. Make sure you order the Flowmeter for PVC pipe and not copper - The part number will end in "P" or "PR".
SELECT AN INSTALLATION SITE - provide a minimum of 8" clearance above the pipe for the Flowmeter. Also the pipe on which the Flowmeter is installed has to be horizontal and 21" long - 6" after the Flowmeter and 15" before the Flowmeter. Install the Flowmeter after the filter. Avoid placing it right after a point where you inject chemicals like chlorine or acid.
