Yokogawa’s new Glass Rotameter RAGN is designed to offer an unlimited lifetime combined with safe and nearly maintenance-free operation. The rotameter resists highly corrosive media and is used for the continuous flow measurement of liquids and gases. The RAGN with reed switches has been assessed to SIL 1 to the reworked IEC 61508:2010 and complies with the Machinery Directive ISO 13849-1 standard. It comes in an all stainless steel design and offers measuring ranges from 2 ml/h – 10 m3/h water and 0.1 l/h – 160 m3/h air. The measuring glass tube is equipped with an easy-to-read scale highlighted by a yellow background and protected by a splinter shield. The modular design limit switches can be easily retrofitted and are used to indicate minimum or maximum flow alarms, by outputting a signal when the magnetic float has reached or exceeded the limit switch position. An optional cable connection box is available for simple wiring. The RAGN lineup combines multiple process connections and sizes in a modern design. – yokogawa-usa.com
