Abstract：
:A flow rate monitor system for constant perfusion of media for maintaining physiological preparations, particularly in vitro brain slices, is described. The system consists of 3 components: the counter with a drip rate meter and alarm; a drop sensor; and a remote DC power supply. It provides accurate and immediate readout of flow rate in drops per minute and it provides an audio warning if the drip rate falls below a level set by the investigator.
