ABSTRACT:
A method and portable apparatus for continually monitoring the flow of fluid in an open channel such as in a conduit having a known diameter, a known slope and of material having known surface characteristics. The liquid depth within the pipe is determined by means of an elongated hollow probe placed axially in the bottom of a channel containing the liquid and forcing gas under pressure there through. The measurement of the back pressure represents the depth of the liquid and enables the rapid determination of the rate of flow. It is contemplated that the portable apparatus be interconnected with a portable continual recorder such that the flow may be monitored over any given, desired, time period.
