Electromagnetic flow measurement
Fields of application
The M3000 and M4000 flowmeters are specially designed for flow measurement in the pharmaceutical and chemical industries, as well as for all water and water treatment sites classified as hazardous areas.
Benefits
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. By adjusting the coil excitation frequency, the M3000 and M4000 converters can be adapted to difficult applications. The new electronics offer improved measurement accuracy, especially at low flow rates.
