What is a Rotameter?
A Rotameter is a mechanical device that measures the flow rate of liquids and gases. It works on the principle of variable area: as fluid flows upward through a tapered vertical tube, it lifts a float whose position indicates the flow rate. Being a constant differential pressure device, a Rotameter is often referred to as a variable area constant differential pressure flow meter or float flow meter. Find detailed technical specifications here: Rotameter Product Details.
- Measurement Principle: Throttling principle with variable area, constant differential pressure across the float.
- Application: Water, chemicals, air, industrial gases, and other process fluids.
- Alternate Names: Float flow meter, variable area flow meter.
Product Overview: The Rotameter manufactured by Hebei JIRS Import & Export Co., Ltd. measures fluid flow using top-grade float and tube assembly and is available in a wide variety of sizes and materials (including glass, plastic, and stainless steel) to suit your specific process needs.
