The new RAGN Glass Rotameter from Yokogawa is designed for the continuous flow measurement of liquids and gases in safety-critical applications where extended operating life and maintenance-free operation are required. The meters are resistant to corrosive media thanks to an all-stainless-steel housing and is equipped with an easy-to-read scale highlighted by a yellow background and protected by a rotating splinter shield preventing glass splinters or aggressive media from escaping to the front in the event of glass breakage.
The modular design allows limit switches to be retrofitted to initiate minimum or maximum flow alarms when the magnetic float exceeds the limit. Ease of wiring is ensured by an optional cable connection box which accommodates different process connections and sizes.
The mechanical design offers a number of benefits in terms of reduced energy consumption and low pressure loss results in low pumping costs and energy savings. Rotameters work without power and under normal operating conditions, are maintenance free and have a virtually unlimited lifetime. Yokogawa has placed great significance on the sustainability of this product at every stage of the product lifecycle. The design uses a large number of standard components from other Yokogawa flow products, leading to synergy in production and to resource and energy conservation.
