Variable Area

Founded in 1984, Meister develops, produces and sell systems for flow measuring and monitoring in industrial environments worldwide. The product portfolio includes devices that cover a wide range of applications for liquid and gaseous media. This is complemented by tailor-made solutions - a particular strength of the company.

Variable Area flow meters, often referred to as “rotameters,” measure flow rate of a liquid or gas by relating linear displacement of an internal “float” to a corresponding flow rate. As flow rate increases, the orifice area that the flow moves through also increases – thus, the term “Variable Area.” Variable Area meters either allow flow through a peripheral orifice formed between a tapered wall and a float as in the traditional rotameter, or an annular orifice and an internal tapered metering pin in the Lake Monitor.
