Ultra-Compact Design: Zero cross-talk for parallel mounting down to 2 mm (0.08") spacing.
2-in-1 Smart Sensing: Simultaneous volumetric flow and temperature tracking via IO-Link & Modbus.
Resilient Construction: PEEK flow tube matrix with 2 mm casted stainless steel housing (Max 16 barg).
Zero Maintenance: Full-bore architecture without moving parts; automated parameter backup.
Executive Summary: The KROHNE AF-E 400 is an ultra-compact wafer electromagnetic flowmeter designed specifically for space-constrained factory automation, cooling manifolds, and dosing skids. Featuring a robust PEEK flow tube, integrated temperature tracking, and digital IO-Link/Modbus communication, it eliminates physical cross-talk and reduces hardware footprints. This expert technical hub covers full specifications, comparison tables, decision trees, procurement checklists, and application guides.
In modern industrial facilities, floor space and manifold space are at an absolute premium. The KROHNE AF-E 400 addresses dense equipment challenges by delivering lab-grade metering accuracy in a housing a fraction of the size of traditional mag meters.
Engineered with a high-strength PEEK matrix and heavy-duty 2 mm casted stainless steel body, the AF-E 400 withstands extreme hydraulic pressure spikes up to 16 barg without mechanical drift.

When replacing existing legacy meters or retrofitting compact skids with the KROHNE AF-E 400, our senior field engineers recommend checking these 5 critical validation parameters prior to issuing a Purchase Order:
Send us your process parameters (medium, flow range, temperature, pressure). Our technical engineering team will issue a full sizing datasheet and direct factory quotation within 24 hours!
Request 24h Factory Pricing & SpecsA: Thanks to zero cross-talk magnetic circuit design, multiple AF-E 400 meters can be mounted parallel touching each other—with clearance down to 2 mm (0.08 inches)—without signal distortion.
A: The AF-E 400 tracks volumetric flow, totalized flow, and temperature in one sensor. This dual-sensor design eliminates buying, drilling, and installing separate temperature sensors, saving up to $150 per measurement point in hardware and labor.
A: To eliminate transaction friction and support urgent replacement orders in the Russian market, we support direct RMB (Yuan) bank transfers. This ensures full regulatory compliance and instant dispatch from our active ex-stock inventory.
A: If your skid expands to require high-pressure direct mass flow tracking or legal-for-trade custody transfer, upgrade your specs to a heavy-duty fiscal system like the Micro Motion ELITE CMF350P Flow Matrix.
