Gear meters are devices used to measure the flow of liquids or gases in various applications. They operate by using rotating gears that capture and displace a specific volume of fluid with each rotation. This movement is then translated into a measurable output, allowing for accurate flow rate readings. These meters are commonly found in industries such as oil and gas, water treatment, and chemical processing. Their design ensures reliability and precision, making them suitable for both low and high flow rates. Gear meters are valued for their durability and ability to handle viscous fluids effectively.
