A liquid flow meter is a device used to measure the flow rate or quantity of liquid moving through a pipe. It operates by detecting the movement of the liquid and converting this information into a readable format, such as gallons per minute or liters per hour. Common types include positive displacement meters, turbine meters, and electromagnetic meters, each suited for different applications and liquid types. These meters are essential in various industries, including water treatment, oil and gas, and chemical processing. They help monitor and control liquid flow, ensuring efficient operation and compliance with regulations. Accurate measurements from liquid flow meters can also aid in resource management and cost savings.
