A liquid flow regulation device utilizing a cage having a passageway with an exit. The shaft converts the vertical displacement motion of the pushing assembly into a swinging motion of the stirring board. Actuation of the pressure sensor positioned in a lit footfall portion generates a first signal to the microprocessor, while actuation of the pressure sensor positioned in an unlit footfall portion generates a second signal. Such BACE mediated disorders include, for example, Alzheimer’s Disease, cognitive deficits, cognitive impairments, schizophrenia and other central nervous system conditions. The electrical current outputted from the sensor is sent to a fuel level gauge which translates the electrical signal into a visual reading, thereby informing an operator of the current fuel level.
