Method and device for measuring and controlling amount of liquid pumped

Abstract

The invention relates to a method and device for measuring and controlling the amount of a liquid pumped. 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.

Description

technical field

[0001] Embodiments herein relate generally to a system for monitoring and metering liquid flow. Embodiments herein relate, inter alia, to a system and method for measuring and controlling the flow / capacity or delivery of a liquid pump. Embodiments herein relate more particularly to a system and method for measuring and controlling groundwater resources. Background technique

[0002] The metering and control of water, i.e. pumped from a source, has always been challenging. Water turbulence, air mixing with water, the probability of tampering and cheating, etc., have all made conventional measurement methods ineffective.

[0003] Rapid population growth and development of human activities increase the demand on natural resources, especially available water. Therefore, access to water should be in balance and controlled by the water resource management system.

[0004] Wells, apart from those imposed on their measuring equipment, pose a real paradox due to t...
