An "online mounted rotameter," or "field mount rotameter," is a device used to measure the flow rate of fluids in a pipeline. It's designed to be installed directly in the flow line itself, hence the "online" or "field mount" designation. These rotameters operate on the variable area principle, where a float within a tapered tube rises and falls depending on the flow rate

A panel-mounted rotameter is a flow meter designed for installation on a panel or control room, used to measure the flow rate of liquids or gases. It operates on the variable area principle, where a float rises within a tapered tube as flow increases, with the float's height directly proportional to the flow rate. 

A flange mounted rotameter is a variable area flowmeter designed with flanges for easy installation into pipelines. These rotameters utilize a float within a tapered tube to measure fluid flow, making them suitable for a wide range of applications, especially in industrial settings where ease of integration and robust construction are important.
