Abstract: A system and method manages an investment portfolio. The system includes at least one processor programmed to receive performance data for a plurality of investable entities forming a market. Risk adjusted discount cash flow (RA-DCF) values are then calculated for the investable entities using the received performance data. In response to at least one trigger, a predetermined number of the investable entities with RA-DCF values less than corresponding current market values are selected and the investment portfolio is rebalanced to include the selected investable entities.

Abstract: A liquid flow sensor produces output signals which are monitored over a known volume of flowing liquid. That monitored signal value is scaled according to a predetermined volume of liquid to provide a correction factor, whereby the output signal of the flow sensor is continually corrected to provide an expected number of flow sensor pulses per unit volume.
