Abstract
A refrigeration system includes a heat exchanger that is operable to cool a flow of compressed refrigerant and a first sensor coupled to the heat exchanger and operable to generate a first signal indicative of a heat exchanger liquid level. A reservoir is in fluid communication with the heat exchanger to receive the flow of cooled compressed refrigerant and a second sensor is coupled to the reservoir and is operable to generate a second signal indicative of a reservoir liquid level. A processor is operable to calculate a first weight of liquid within the heat exchanger in response to the first signal, and to calculate a second weight of liquid within the reservoir in response to the second signal.
