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.
Specifications

|---|---|
| Range dimension / lining material | neoprene DN50 ÷ DN300 |
| Sensor material | SS321 |
| Housing material | epoxy painted aluminium |
| Electrodes material | SS316L – Hastelloy C |
| Measure range | <3m³/h ÷ >2400m³/h |
| Accuracy | ±0,5% standard; ±0,2% optional |
| Repeatability | ±0,1% |
| Fluid conductivity | >5μS/cm. |
| Power supply | 85÷265Vac, 24Vac/dc, 12Vdc. |
| Consumption | 6W, max. 8W. |
| Ambient Temperature Limits | Remote version operating temperature: -10 ÷ +80°C Compact version operating temperature: -10 ÷ +80°C Storage temperature: -40÷85°C |
| Communication protocol | Modbus RTU or Bluetooth App Android (opt.) or Hart (opt.) |
| Data Logger | Internal data logger to USB pen drive for flow measurements and analog inputs storing; the measurement storage interval can be set from 15 to 3600 seconds |
| Output | 4÷20mA: 0÷500Ω Frequency output: 0,1÷10000Hz Pulse output: 24Vdc galvanically isolated or open collector galvanically isolated 24V 20mA (opt) Alarm output: 2 relays, 3A 230Vac N.O. |
| Input signals | RKMAG has 2 active analog inputs at 24Vdc for 2-wire transmitters connection (eg. Temperature or pressure) and 1 digital input for an external contact connection for the integrated batch function restart and for partial totalizer management. |
| Reverse Flow | Allows measure and totalization of reverse flow. |
| Output Testing | Relays output: Transmitter can switch relays at testing value. Current Source: Transmitter can be commanded to supply a specified test current between 4.0 and 20.0 mA. Frequency Source: Transmitter can be commanded to supply a specified test frequency between 1 ÷ 10000 Hz. |
| Low Flow Cutoff | Adjustable. Below selected value, instantaneous flow and outputs are driven to the zero flow rate signal level. |
