SGM Lektra presents a new type of electromagnetic flowmeter with plastic sensors: RKmag. Because of its particular inner shape the mounting of the unit requires no straight pipe lengths before and after the meter. The converter is equipped with a large, bright, removable O-LED display and can mount a pen-drive USB data logger. The configurable outputs can be analogic, pulse and MODBUS RTU and alarm messages are managed by 2 configurable relays. RKmag is suitable for use with a wide range of conductive liquids, even chemically aggressive: the electrode materials can be selected according to the chemical properties of the fluid.
