      	| FTB500 series low flowmeters offer extremely accurate low flow measurement of liquids. They utilize a pelton wheel-like rotor whose motion is converted by a pickup coil into a pulse output that is proportional to flow . Each flowmeter comes with an integral signal conditioner, powered by either 15-35 Vdc or 115 Vac (opt.) to provide amplified frequency and analog outputs. The signal conditioner corrects for the inherent zero offset of the flowmeter pulse output. It is mounted in a NEMA-4, explosion-resistant enclosure rated for class I, groups C & D, class II, groups E, F, and G.
