ABSTRACT:
A flow meter for detecting and recording a plurality of data points representative of the depth and velocity of liquid flow in an open container. A weighted sensor has a dimpled surface to induce turbulence at low velocities to assure a substantially linear velocity characteristic. An electromagnetic velocity transducer and a single tube bubbler are engaged to the sensor to provide data which is periodically read into a cassette recorder. A microcomputer controls timing functions with respect to the collection and recordation of data within the system.
