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.

Flow meter

A method for detecting the depth of a liquid body. A source of pressurized gas is engaged to a weighted sensor by means of a single elongated tube. The sensor is positioned at the bottom of the liquid body. A solenoid valve, which regulates the flow of gas in the tube, is periodically opened to provide a pulse of overpressure which exits the underside of the sensor in a pressure-equalizing stream of bubbles. After a brief, predetermined settling time, a reliable pressure/depth indication is obtained from a transducer in communication with the single tube.
