Abstract
An automatic liquid sampling and flow measuring apparatus provided as a unitary structure within a case, and capable of collecting liquid samples at selected intervals, measuring flow rate through a channel at selected intervals, and collecting and storing sampling and flow rate data for later retrieval. The apparatus is provided with its own self-contained microprocessor for automatically controlling sampling operations, calculating flow rate on the basis of signals from a sensor, and storing data relating to sample collection and flow rate measurement. The stored data can be called up on a display of the apparatus, or can be transferred via a portable transfer unit to an external output device, such as a printer capable of producing a hard copy of the data.
