Specifications
The M2000 converter is one of the best solutions for bidirectional flow measurement of liquids with conductivities > 5 μS/cm (> 20 μS/cm for demineralized water).
Accurate, the M2000 is easy to use and can be adapted to a wide range of industrial applications. The 4-line backlit LCD display provides simultaneous indication of measured flow rate, totalization and all information, including alarm messages. The converter comes as standard with a current output, 4 programmable logic outputs, an AC or DC power supply and an RS232 Modbus ® interface.
Powerful internal self-test functions enable continuous diagnostics of the converter and associated sleeve, ensuring safe operation.
