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.


Flow rate range RKMAG is able to process signals from fluids with flow rates of up to 10m / s in both directions (bidirectional meter).
