Liquid flow meter

摘要: To measure a wide range of flow rates, and particularly such low rates as 0.5 liters per hour, while being able to accurately also about 100 fluid is introduced axially into rotor (14, 36, 40) which has outlet openings (24, 45) positioned at their circumference, the rotated by reaction on upon from openings. The operates within chamber (15) conducted outwardly through duct thereabove. Inflow may be guided for linear guide ribs (13). hollow disk-like structure (FIGS. 1-3) with spiral vanes therebetween, or T-shaped tubular 4-6). If fuel consumption an internal combustion engine measured in pressurized supplied excess returned, two meters can combined common shaft, respectively oppositely facing (36, 45), so that differential only measured, hence measuring engine. Rotation sensed electro-optical sensor (29, 37).
