Kobold DON-220HR43E3M0 Product Overview
The Kobold DON-220HR43E3M0 is a high-precision positive displacement oval gear flow meter engineered explicitly for tracking and monitoring viscous, non-abrasive, clean industrial liquids. Built with a heavy-duty 316L stainless steel housing and specialized stainless steel oval gears, this robust volumetric flow transmitter delivers precise, continuous flow measurement independent of changes in media viscosity or flow profile.

High-Accuracy Volumetric Displacement Technology
The DON-220HR43E3M0 operates using two precisely machined, interlocking oval gears within a chamber. As fluid travels through the meter, it causes the gears to rotate, moving a fixed and repeatable volume of liquid with each single revolution. High-resolution magnets embedded inside the gears pass their rotational coordinates to the integrated U-PACE electronic head. This measurement principle ensures an outstanding reading accuracy of up to $\pm0.2\%$ to $\pm1\%$, while completely eliminating the need for straight inlet or outlet pipe conditioning.
Intelligent Industrial Automation & Display Functions
Equipped with Kobold’s proprietary U-PACE (Universal Precision and Control Electronics) module, the DON-220HR43E3M0 features a vibrant, rotatable multi-parameter TFT display. Operators can easily cycle through live flow rates, media temperatures, and resettable totalizer counts via intuitive optical touch keys. Supporting both modern IO-Link architectures and traditional analog/pulse networks, this intrinsically safe ATEX-rated flow meter is ideal for chemical batching, lubricant monitoring, fuel lines, and precision dosing lines.
