Rotameters or variable area flow meters operate by flowing a fluid through a conical flow tube. Our rotameters are either visual flow meters only, or allow an analog signal to be recieved at a control system.
Series 2000 glass tube variable area purge meters are available in 100mm, 150mm and 300mm tube lengths and with optional fine threaded regulating valve for precise flow measurement. They are suitable for gas and liquid flow measurement and control.
Series 6000 glass tube rotameters are designed according to VDI/VDE 3513 standards. Its clear borosilicate tapered glass tube with scales help flow reading with great accuracy and ease. End connection options such as screwed end connections, flanges and sanitary couplings make it suitable process industry requirements.
