The Variable-Area Flowmeters, also known as rotameters, offer a simple yet highly effective method for measuring fluid flows through a tapered tube. These meters deliver reliable, mechanical readings without the need for power, making them suitable for lab setups, pilot plants, and hazardous environments. With clear float indicators and durable materials, they deliver consistent and visible measurement. Available for gases or liquids and in multiple sizes, they enable accurate flow monitoring and adjustment with minimal maintenance. Trusted in process labs and controlled settings, these instruments offer a low-cost, dependable solution for visual flow control.
