Specifications

The converter enables flow measurement in hazardous areas classified as Ex zone 1 and 2, in compact or remote mounting. The electronics are mounted in a cast aluminum housing with
IP67 protection. An internal partition provides physical separation from the various terminal blocks. Configuration can be carried out with the lid closed, using a magnetic pen, or with the lid open, using 3 keys. The 4-line display shows measured flow rate, totalizers and various status messages. Adjustable coil excitation frequency allows M3000 and M4000 converters to be adapted to demanding applications. The new electronics offer improved measurement accuracy, especially at low flow rates.
