Liquid metering is the process of measuring the flow rate or volume of liquids in various applications, such as in industrial processes, water supply systems, and fuel dispensing. This measurement is crucial for ensuring accurate billing, maintaining system efficiency, and monitoring environmental compliance. Different types of liquid meters, including positive displacement meters, turbine meters, and electromagnetic meters, are used depending on the specific requirements of the application. These devices help in tracking liquid consumption, managing resources, and optimizing operations across various industries, including oil and gas, water treatment, and food and beverage.
