Abstract: The embodiments herein disclose a method and system for measuring and controlling an amount of flow and volume of liquid/fluid and/or electrical energy. The method and system obtains a plurality of values for the electrical parameters of an electro-pump, including voltage value, current value and active/reactive energy value; calculates the plurality values; and determines and controls the amount of instant flow and volume of the liquid/fluid based on the calculated values. The system/method gathers these two measuring and controlling features such as measuring and controlling the volume of liquid and amount of energy in one casing, thereby providing a secure reference for both the parameters at the same time for underground water resources.
