Banjo’s three-inch manifold magnetic flowmeter displays batch total volume and overall total volume. The flowrate allows for gallons or liters per minute while the display reads six digits for rate, eight digits for total, and one decimal place reading in tenths. This self-calibrating magnetic-style meter with stainless steel electrodes can be used for measuring water and most conductive liquids. Other features include no moving parts to fail during use, glass-reinforced polypropylene, a temperature range from 0 F to 150 F, and 99 percent accuracy from 14 GPM to 670 GPM for three inches. It runs on six AA batteries.
