WATERFLUX 3400

Electromagnetic flowmeter engineered for water applications with zero straight-pipe requirements and wireless connectivity.

The WATERFLUX 3400 is an electromagnetic flowmeter specifically designed for demanding water measurement tasks where installation space is constrained. Its 0D inlet/outlet design eliminates the need for extended straight-pipe runs, reducing installation complexity and footprint while maintaining measurement accuracy. Available in compact (C) and field-mounted (F) configurations with multiple connection standards (EN, ASME, JIS), the meter supports up to 3 analogue outputs plus discrete and digital outputs including HART® and Bluetooth® for flexible integration and remote monitoring. Fully certified for potable water applications (DVGW, NSF, WRAS, KIWA) and hazardous areas (ATEX, IECEx), it delivers reliable performance across -5…+70°C and pressures to 16 barg.
