Electromagnetic Flowmeter MAGNETOFLOW™ M3000/4000
The amplifier with modular design allows flow measurements, in either the mounted or remote version in classified hazardous area (eg. zone 1 and 2). The amplifier housing, made of powdercoated aluminium, is available in protection class IP67 and with a separate connection space. Programming can be done either with closed housing thanks to a magnetic pen or with open housing via three buttons. The four-line display shows all necessary data like actual flow, totalizer and status messages.
The programmable excitation frequency even enables the amplifier to be adjusted for difficult metering applications. The newly developed process for amplifier compensation enables a high accuracy, especially in the lower flow range. The M3000/M4000 is especially suited for flow measurements in chemical and pharmaceutical industries, as well as water and waste water plants with explosion-proof zones.
