A flow meter is a device used to measure the flow rate of liquids or gases in a system. It helps determine how much fluid is moving through a pipe or channel over a specific period. Flow meters are essential in various industries, including water treatment, oil and gas, and food processing, ensuring efficient operation and accurate billing. There are several types of flow meters, such as mechanical flow meters, electromagnetic flow meters, and ultrasonic flow meters. Each type operates on different principles and is suited for specific applications. By providing precise measurements, flow meters help optimize processes and maintain safety standards.
