A flow meter is an essential device used to measure the flow rate or quantity of a liquid or gas moving through a pipe or conduit. These meters are widely used in industries such as water treatment, oil and gas, pharmaceuticals, and manufacturing to ensure accurate monitoring and control of fluid flow. Flow meters come in various types, including mechanical, electromagnetic, ultrasonic, and thermal, each suited for specific applications. They provide reliable, real-time data that helps optimize processes, improve efficiency, and maintain system safety.
